HFV (Hidden Folder Virus) Cleaner Pro
A Small Utility programmed to destroy Win32:Atraps-PZ[Trojan]

Assuming these shortcuts as innocent, we launch them which in turn infects our PC or laptop with a virus which the geeks call Win32:Atraps-PZ[Trojan] Simply speaking, the shortcut creates a backdoor to your system so that it can access all your files,services and privileges within that system & all others connected to it without your permission. This is where HFV comes to help...Simply paste the location of your Infected directory on the box & click Delete virus to get rid of virus. As a safety precaution, keep this software backed up on system as well since the virus which hides all files and creates a shortcut can also hide this software as well.

SpeedFan
SpeedFan is an advanced system monitoring tool

If you are trying to figure out why your PC hangs when under heavy load or after some hours of usage, SpeedFan might help you find the real cause. Very often it is a poor power supply, or an improperly installed heatsink that lead to behaviours that we tend to associate (incorrectly) with errors from the operating system. SpeedFan automatically searches your computer for informative chips: the hardware monitor chips. SpeedFan can display voltages, fan speeds and temperatures. On rare occasions, the BIOS doesn't activate such features. SpeedFan tries to enable them as long as this is a safe thing to do. Not only the motherboard is searched, but also some video cards and almost every currently sold hard disk. SpeedFan can access status info from EIDE, SATA and even SCSI drives -
