ABSTRACT:
A recovery technique allows a computer program to be recovered from a program which has been infected with a computer virus. Prior to the program being infected, a unique fingerprint of the program is taken and stored along with data relating to the beginning portion of the program at a location separate from the program. A program thought to be infected is processed by generating a fingerprint of a string in the program utilizing the stored data. The fingerprint that is generated is compared with the stored fingerprint to determine whether or not the two fingerprints match. If the fingerprints match, the program is restored from the stored information and the string. If the fingerprints do not match, the value utilized to select the string can be incremented and the process repeated.
