Abstract

"SISTEMA DE DETECçãO DE VìRUS". Trata-se de um método para curar um vírus criptografado presente em um sistema de computador que inclui analisar os dados criptografados para determinar pelo menos um byte criptografado ocorrendo mais freq³entemente nos dados criptografados, calcular uma chave de criptografia baseado no byte criptografado ocorrendo mais freq³entemente e em um byte original esperado correspondente dos dados originais e decriptografar os dados criptografados utilizando a chave de criptografia para restaurar os dados criptografados para os dados originais.
