Detailed ways

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be more thoroughly understood, and will fully convey the scope of the present disclosure to those skilled in the art.

The embodiments of the present invention provide a file cleaning method, an electronic device and a server, which are used to solve the technical problem that the cleaning policy control for an application program in the prior art is not precise enough.

The general idea of the technical solutions in the embodiments of the present application for solving the above-mentioned technical problems is as follows:

When cleaning the first application, two sets of cleaning policies can be obtained, which are: the first cleaning policy obtained from the server and the default cleaning policy of the electronic device. The first cleaning policy is based on the first application in the electronic device. The installation location on the application is determined; then a cleaning strategy can be selected to clean the first application based on the cleaning priority of the first cleaning strategy and the cleaning priority of the default cleaning strategy. The default cleaning strategy of an application cleans the first application, but provides multiple cleaning strategies for selection, thus achieving the technical effect of more precise control of the cleaning strategy.

In a first aspect, an embodiment of the present invention provides a file cleaning method, please refer to FIG. 1 , including:

Step S101: Acquire a first cleaning strategy for cleaning a first application from a server, where the first cleaning strategy is determined based on an installation location of the first application on an electronic device;

Step S102: judging whether the cleaning priority of the first cleaning strategy is higher than the cleaning priority of the default cleaning strategy;

Step S103: if yes, clean up the first application program through the first cleaning strategy;

Step S104: If no, clean up the first application program through the default cleanup policy.

For example, the solution is applied to an electronic device, such as a mobile phone, a tablet computer, a notebook computer, and the like.

This solution can be applied to the cleaning process of a single application. For example, if the user wants to uninstall the browser A installed on the electronic device, he can first select the browser A, and then perform the cleaning operation (for example, click the cleaning button, generate the cleaning gesture etc.), then the first application can be browser A, and the subsequent steps S101 to S104 can be used to clean up browser A; this solution can also be applied to the cleaning process of multiple applications, for example: the user The application management software carried by the device scans out the applications installed on the electronic device, and then selects some applications (for example: browser A, music player B, microblog C, etc.), and then performs the cleaning operation, then The application programs selected by the user may be respectively used as the first application programs, and subsequently, it may be determined through the solutions provided in steps S101 to S104 that each application program selected by the user should be cleaned up.

In step S101, the installation location of the first application on the electronic device can be obtained through the following steps: searching for a PE (Portable Executable: Portable Executable) file of the first application on the electronic device; The location where the PE file is located is used as the installation location of the first application.

For example, the PE file of the first application can be searched through the registry Uninstall item or the startup item, etc., and then the installation location of the first application and the corresponding PE file can be obtained; or through the desktop shortcut, the start menu shortcut , scheduled tasks, service items and other common entrances to find the PE file of the first application, and then obtain the installation location and PE file of the first application, etc. Of course, the installation location of the first application can also be obtained in other ways. The embodiments of the invention are not listed in detail and are not limited.

PE files are usually program files on the operating system, such as: EXE (executable program: executable) files, DLL (Dynamic Link Library: Dynamic Link Library) files, OCX (Object Linking and Embedding: Object Class Expansion Components) files, SYS ( SYSTEM: System) file, COM (Component ObjectModel: Component Object Model) file and so on.

PE files can include one or more of the following information: message digest information (for example: MD5 information), icon information, signature information, file size, creation time, access time, modification time, version number, whether to bundle other applications, Whether there is rogue behavior (for example: locking the home page, popping up advertisements, performing various illegal operations in the background, etc.). After the installation location of the first application is determined, the installation location information of the first application can be directly sent to the server; the electronic device can also generate a log file from the installation location of the first application and the PE file, and then the log file It is sent to the server, and after receiving the log file, the server extracts the installation location information of the first application program from the log file.

In the specific implementation process, the server may pre-store a cleaning strategy set for cleaning each application. The cleaning strategy set may be a database or a corresponding relationship list, and the cleaning strategy set includes at least one application and its For the corresponding cleaning strategy, the cleaning strategy of the corresponding application can be found in the cleaning strategy set through the program name of each application or other parameters (eg icon number, version number, etc.) and the installation location of the application.

Alternatively, all the cleaning strategies included in the corresponding application can be obtained by searching the cleaning strategy set through the program name or other parameters (for example: icon number, version number, etc.) of each application, and then The installation location looks for the cleaning strategy of the corresponding application in all cleaning strategies of the application.

As an optional embodiment, the server may determine the first cleanup policy corresponding to the first application in the following manner: Determine the first cleanup policy by using the PE portable executable file of the first application. The identification information of the application; the first cleaning strategy is obtained by searching the cleaning policy set through the identification information and the installation location.

For example, when some applications may be installed on different electronic devices, their program names or other parameters (such as icon number, version number, etc.) may change, so it may not be possible to accurately find the cleaning strategy library. Corresponding cleaning strategy, therefore can first accurately determine the identification information of the first application through the PE file of the first application (the identification information is used to uniquely identify the first application), and then pass the identification information and the installation location. Find the corresponding cleaning strategy in the cleaning strategy collection. Wherein, the identification information and the installation location can be matched in the cleaning strategy set at the same time, and then the cleaning strategy that matches both the identification information and the installation location can be obtained as the first cleaning strategy corresponding to the first application; Search in the cleaning strategy set to obtain all cleaning strategies corresponding to the identification information, and then search for the first cleaning strategy corresponding to the installation location from all cleaning strategies corresponding to the identification information through the installation location.

Wherein, the identification information of the first application can be determined by the program name, icon information, signature information, file size and other information of the first application. For example, if the icon information of some applications will not change, an The icon identification library corresponding to the icon information; for some applications whose signature information will not change, you can set a signature identification library corresponding to the signature information, etc. For some applications, the program name + file size can uniquely characterize the application. Then you can set a program name + the corresponding identification library of the file size, etc., and then search in each identification library through the parameters of the first application, for example: use the icon information of the first application in the icon identification library. Search, if the corresponding identification information is found, then the found identification information is used as the identification information of the first application, and the search is stopped; if the corresponding identification information cannot be found, the signature information of the first application is used to sign the Continue searching in the identification library until the identification information location of the first application program is found.

Since in the above solution, the first application program can be uniquely identified by the identification information of the first application program, the first cleaning policy corresponding to the first application program can be found more accurately.

In step S102, for example, the cleaning priority of the default cleaning strategy can be set to a fixed value (for example: 1, 2, etc.), and for the first cleaning strategy determined based on the installation location, the cleaning priority is in an adjustable state. For example, the server may determine the cleaning priority based on the cleaning result report information of cleaning the first application program on each electronic device through the first cleaning policy.

In the specific implementation process, the cleaning result report information may contain a variety of information, two of which are listed below for introduction. Of course, in the specific implementation process, it is not limited to the following two situations. In addition, in the case of no conflict, the following Both cases can be used in combination.

First, the cleaning result report information includes: mistakenly deleted information.

In the specific implementation process, a plurality of electronic devices used for the experiment can be determined first, and the first application program is installed on these electronic devices. The server can assign the first cleaning strategy to these electronic devices, and then these electronic devices pass the first A cleaning strategy cleans the first application. After the cleaning is completed, a professional judges whether there is an accidental deletion when cleaning the first application. If there is an accidental deletion, it is reported to the server, and the server based on the The accidental deletion situation determines the accidental deletion information, and the accidental deletion information includes, for example, at least one of the probability information of the accidental deletion and the file type information of the accidental deletion. Divide the number by the total number of electronic devices; for example, the types of files deleted by mistake include: system files, non-system files, etc. The severity of the accidental deletion can be determined by the type of files deleted by mistake. If the type of files accidentally deleted includes system files , it can be determined that its severity is high, if it does not contain system files, it means that the severity of accidental deletion is low, and so on.

Second, the cleaning result report information includes: omission and deletion information.

For example, the missing deletion information includes, for example, at least one type of information among: probability information of missing deletion, number of files missing to be deleted, and number of electronic devices with missing deletion. The probability information of missing deletions includes: information on the proportion of electronic devices that are missing to be deleted, the proportion of files that are missing to be deleted, etc. The number of electronic devices that are missing to be deleted can be obtained by dividing the number of missing electronic devices by the total number of electronic devices. , the information on the proportion of missing files can be obtained by dividing the number of missing files by the total number of files (for example: the sum of the number of deleted files and the number of missing files).

As an optional embodiment, the server may obtain the cleaning priority corresponding to the first cleaning strategy in the following manner: obtaining the preset priority of the first cleaning strategy; The priority is set for adjustment, so as to obtain the cleaning priority of the first cleaning strategy.

For example, for the first cleaning strategy determined based on the installation location, a default preset priority (for example: 2, 1.5, etc.) can be set for it, and then the preset priority can be adjusted based on the cleaning result report information , so as to obtain the cleaning priority of the first cleaning strategy.

For example, if there is no accidental deletion information, the preset priority can be kept unchanged when the preset priority is adjusted based on the accidental deletion information; Adjust, for example: if the probability of accidental deletion is high, the corresponding cleaning priority will be greatly reduced; if the probability of accidental deletion is low, the corresponding cleaning priority will be reduced slightly; if the mistakenly deleted file contains If the deleted file does not contain system files, the corresponding cleaning priority will be reduced to a lesser extent, and so on.

The adjustment method of the cleaning priority based on the missing deletion information is similar to the adjustment method based on the mistaken deletion information. For example: if the probability information of missing deletion is 0%, the cleaning priority will not be changed; if 0% < probability information of missing deletion ≤ 10%, the preset priority can be reduced by a gradient (for example: reduce by 0.5) ; If 10%<cleaning comprehensive rate≤20%, the preset priority can be reduced by two gradients (for example: reduce by 2*0.5) and so on.

In step S103, if it is compared that the cleaning priority of the first cleaning strategy is higher than the cleaning priority of the default cleaning strategy, the cleaning of the first application on the electronic device can be realized by the following steps: A snapshot of files generated when the first application is installed determines a set of files to be cleaned when cleaning the first application; File types are cleaned up.

For example, under normal circumstances, when the first application is installed, a corresponding snapshot can be generated by a tool of the electronic device, and the snapshot includes which files are generated when the first application is installed, and the location of these files, from the snapshot The generated files can be directly extracted from the file, and these generated files constitute a set of files to be cleaned, wherein the corresponding files to be cleaned can be obtained through snapshots after the first application is installed, or the first application can be cleaned , the corresponding file to be cleaned is obtained based on the snapshot, which is not limited in this embodiment of the present invention. For example, install the 360 security browser, it will generate the following files:

%AppData%\360se6\

%Desktop%\360 Safe Browser.lnk

HKEY_CURRENT_USER\Software\360\360se6

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall\360se6

…

Wait.

After obtaining the file to be cleaned up, the first application program can be cleaned up through the first cleaning strategy.

For the above 360 security browser, we can determine the following content to be deleted based on its snapshot and the first cleaning strategy:

Delete folder: %AppData%\360se6\

Deleted file: %Desktop%\360 Safe Browser.lnk

Delete the registry:

HKEY_CURRENT_USER\Software\360\360se6

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall\360se6

Wait.

As an optional embodiment, after the first application is cleaned up based on the first cleaning policy, a reverse check mechanism may be added to perform reverse check at some common locations on the electronic device according to deleted files and folders. For example: check the desktop shortcuts, start menu shortcuts, service items in the registry, startup items, CLSID, AppPath, Uninstall items, etc. on the electronic device. If it points to the location of the PE file, it is our To delete files or folders, the shortcuts and registry entries for those locations are deleted, and the user is given a clean system.

In step S104, if the cleaning priority of the first cleaning strategy is not higher than the cleaning priority of the default cleaning strategy, the first application may be cleaned up through the default cleaning strategy. The default cleanup policy refers to the cleanup rules generated for the application in the early stage (for example: the cleanup rules generated when the application is installed), and the corresponding files, folders, Hard-coded native library rules for registry, service items, etc. Each software corresponds to a corresponding library. Each software has a unique software ID, and each software ID corresponds to a unique cleaning rule. That is, a software corresponds to a local only cleaning rule. It is generally not much different from the software installed in the normal path, but the rules are more complicated to write, including all files, subfolders and registry entries, and usually, the default cleanup policy does not have an anti-check mechanism.

As an optional embodiment, the method further includes: obtaining tag information determined by the server for the first application and used for providing the user to the user, where the tag information is used to The PE portable executable file on each electronic device is determined, and M is a positive integer.

In the above solution, the label information can be determined for the first application program through the PE file instead of using the default label information, thus achieving the technical effect that the determined label information of the first application program is more accurate.

In the specific implementation process, when determining the label information of the first application program through the PE file, a variety of parameters can be used, two of which are listed below for introduction, of course, in the specific implementation process, it is not limited to the following two situations , in addition, the following two cases can be used in combination without conflict.

First, the label information is obtained by: determining from the PE portable executable files of the first application on M electronic devices that the first application is in the M electronic devices The program behavior data on the electronic device; the label information is determined through the program behavior data.

For example, the server can determine the program behavior data of the first application program on each electronic device by analyzing the PE file of the first application program on each electronic device, and the program behavior data includes, for example: whether other application programs are bundled, Whether it is running secretly in the background, and whether there are other rogue behaviors (for example: software self-starting, stealing traffic, etc.), different label information can be corresponding to each program behavior, for example: if the first application is bundled with other applications, then The corresponding label information is, for example, a bundled plug-in; if the first application runs secretly in the background, the corresponding label information is, for example, running in the background; if the first application is self-starting, the label information is, for example: software Self-starting, if there is a situation of stealing traffic in the first application, the label information thereof is, for example, stealing traffic and so on. Among them, the server can obtain the corresponding label information for each type of program behavior, and then send it to the electronic device; because the area for displaying the label information is limited, the number of occurrences of the corresponding program behavior can also be counted for each type of label information. , and then sort each tag information from high to low based on the number of occurrences, and finally obtain the tag information that is ranked in the first few digits (for example: 2 digits, 3 digits, etc.), and provide it to the electronic device.

Based on the above solution, the technical effect of determining the label information of the first application program based on the program behavior data of the first application program is achieved. Therefore, the behavior of the first application program on the electronic device can be determined by the label information of the first application program. prompt.

The second is to determine, from the PE portable executable files of the first application on the M electronic devices, the user behaviors generated by the users of the M electronic devices for the first application data; the tag information is determined based on the user behavior data.

For example, the user behavior data includes, for example, the last usage time, the number of usage times, the installation time, and the like. The label information can be directly the user behavior data, for example: the last use time is 3 days ago, the user has used it 5 times in total, the installation time is 1 month ago, etc.; the label information can also be other data determined based on the user behavior data Label information, for example: if the last used time is greater than the preset time value from the current time (for example: half a month, 1 month, etc.), it can be determined that the label information is "the user has not used it for a long time", for example, if the user If the number of times of use is less than the preset number of times (for example: 3 times, 5 times, etc.), it can be determined that the tag information is "the user rarely uses" and so on.

Based on the above solution, the technical effect of determining the label information of the first application program based on the user behavior data of the user for the first application program is achieved, so the user can be prompted for the usage of the first application program through the label information of the first application program. .

In addition, in the specific implementation process, prompt information for whether to clean up the first application program can also be generated based on the PE file. For example, whether the first application program has rogue behavior (for example, bundled software, software self-assembly, etc.) can be determined through the PE file. startup, pop-up ads, stealing traffic, etc.), if there are these rogue behaviors, a prompt message suggesting cleaning the first application can be generated, for example, "The first application has adverse effects on the device, it is recommended to immediately Alternatively, it can be judged whether to clean up the first application program by the user's situation of the first application program, for example: it can be judged whether the usage time of the user's last use of the first application program is greater than the current time from the current time value ( For example: half a month, 1 month, etc.), if it is greater than the preset time value, a prompt message for recommending to delete the first application is generated. For another example, determine whether the number of times the user uses the first application is less than a preset number of times (for example: 3 times, 5 times, etc.), if it is less than, then generate a prompt message suggesting cleaning the first application program, the prompt information is, for example, "The user rarely uses the application, it is recommended to clean the application", etc. Of course, the prompt information can also be other prompt information, and can also be generated based on other principles, which are not listed in detail in this embodiment of the present invention, and are not limited.

In the second aspect, based on the same inventive concept, an embodiment of the present invention provides a file cleaning method, please refer to FIG. 2 , including:

Step S201: obtaining the installation location of the first application on the electronic device;

Step S202: determining a first cleaning strategy for cleaning the first application on the electronic device through the installation location;

Step S203: Send the first cleanup policy to the electronic device, so that the electronic device cleans up the first application based on the first cleanup policy and the default cleanup policy of the first application .

In step S201, the determining the first cleaning strategy for cleaning the first application on the electronic device according to the installation location includes: using a PE portable executable of the first application. The identification information of the first application program is determined from the file; the identification information and the installation location are searched in the cleaning strategy set to obtain the first cleaning strategy.

In step S202, when the first cleaning strategy is determined based on the installation location, various methods can be used, two of which are listed below for introduction. Of course, in the specific implementation process, it is not limited to the following two situations.

First, the searching and obtaining the first cleaning policy from the cleaning policy set based on the installation location includes: judging whether the installation location is located in a predetermined installation location; if the installation location is located in the predetermined installation location location, the determined first cleaning strategy is a cleaning strategy for cleaning the first type of files; if the installation location is not located in the predetermined installation location, the determined first cleaning strategy is for the first cleaning strategy. A cleaning strategy for cleaning up two types of files, the first type of files and the second type of files are not exactly the same.

For example, the predetermined installation location includes, for example, a system-critical installation location, such as a system root directory, a Program Files root directory, a Programs Files (x86) root directory, and the like. The files installed in these directories, if the cleaning strategy is not appropriate, will often lead to deletion of system files, resulting in system failure. Therefore, in order to prevent this situation, different measures can be taken according to whether the first application is installed in the predetermined installation location. First cleanup strategy.

Wherein, when cleaning up an application, the cleaning strategy includes, for example, deleting a specified folder, deleting a specified file, deleting the registry, deleting a driver, deleting a service item, deleting an input method, and so on. Further in the specific implementation process, the first type of files, for example, includes: a single file, a folder, a registry, a driver, a service item, an input method, etc.; the second type of file, for example, includes: a driver, a service item, an input method, etc., Among them, at least some of the files in the first type of files and the second type of files are different, for example, the included files are different, the included folders are different, and so on.

For example, if the application is installed in its own directory (that is to say, it is not installed in the predetermined installation location), for example: Browser A is installed in the %ProgramFiles%\BrowserA\ directory, which is a normally installed application , it can be determined that the second type of files include: files and folders in the BrowserA directory and its subdirectories, as well as registry entries and shortcuts pointing to this installation location, so that the first application program is cleaned up through the first cleaning strategy You can delete all the files and folders in the BrowserA directory and its subdirectories, and then delete the registry entries and shortcuts pointing to this installation location.

And if the application is installed in a predetermined installation location, for example, if browser A is installed in the root directory of the disk (such as C:\), it does not generate its own dedicated directory, and all files are placed in the C drive directory, so It cannot be deleted according to the installation location, otherwise the system folders and other programs will be deleted, resulting in the loss of system and other program files. The first type of files corresponding to the first cleaning strategy at this time include, for example: the application itself In the first cleaning strategy, specific files will be specified to prevent accidental deletion, and then the corresponding registry and shortcuts will be deleted.

In the second type, the searching and obtaining the first cleaning strategy from the cleaning strategy set based on the installation location includes: determining the corresponding relationship between the installation location of the first application and the cleaning strategy; The installation location of the application is searched in the corresponding relationship to obtain the corresponding first cleaning policy.

For example, the storage space of the electronic device can be divided into multiple areas, such as: the root directory of Program Files in the system disk, the root directory of non-Program Files in the system disk, the non-system disk, etc., and then different cleaning policies can be set for each area ,As shown in Table 1:

Furthermore, after the installation location of the first application on the electronic device is determined, it can be determined which installation area the installation location belongs to, and then the corresponding first cleaning policy is obtained by searching the installation area.

In step S203, for example, the electronic device may use the first cleaning strategy and the default cleaning strategy to jointly clean the first application, for example: first cleaning the first application through the first cleaning strategy, and then cleaning the first application through the default cleaning strategy. Clean up the first application, or first clean up the first application by using the default cleaning policy, and then clean up the first application by using the default cleaning policy, etc.; the electronic device can also use the first cleaning policy and the default cleaning policy Selecting a pair of first applications to clean up, for example, the server may also send the cleaning priority corresponding to the first cleaning policy to the electronic device, so that the electronic device can perform cleaning based on the cleaning priority and all The cleaning priority of the default cleaning strategy selects a pair of the first application to be cleaned from the first cleaning strategy and the default cleaning strategy.

In this case, the method further includes: determining a cleaning priority of the first cleaning strategy based on cleaning result report information of cleaning the first application program on each electronic device through the first cleaning strategy class.

As an optional embodiment, the cleaning priority of the first cleaning strategy is determined based on cleaning result report information of cleaning the first application program on each electronic device through the first cleaning strategy , comprising: obtaining the preset priority of the first cleaning strategy; and adjusting the preset priority based on the cleaning result report information, so as to obtain the first cleaning strategy.

As an optional embodiment, the method further includes: respectively obtaining relevant data information of the first application from M electronic devices, where M is a positive integer; based on the data obtained from the M electronic devices The relevant data information determines the tag information of the first application for providing to the user.

As an optional embodiment, the determining, based on the relevant data information obtained from the M electronic devices, the tag information of the first application for providing to the user includes: from the The relevant data information obtained by the M electronic devices determines the program behavior data of the first application on the M electronic devices and/or the users of the M electronic devices target the first application User behavior data generated by a program; the tag information is determined based on the program behavior data and/or the user behavior data.
