An appending virus takes a lot of steps to attach to a host program. Technically, the virus searches for a file and then calculates its delta offset to determine the exact file size. Then it takes the file attributes and saves them to restore them later to make the file appear to be unedited. It then checks the file to determine whether it is already infected.
If not infected, the appending virus attaches itself to the end of the program file. After it has lodged itself into the host, the virus restores all the attributes the file had before it was modified so that no traces of modification appear. Anti-virus programs sometimes have trouble detecting a well-written appending virus. Because it encrypts itself, the encryption is different for all iterations of the virus.
The scanner cannot directly detect the virus, but can still detect the decrypting module of the virus and flag it as malicious. The only thing similar on all the different instances of the virus is the decrypting module. GCSE Exams. Graduate Entrance Exams. International Baccalaureate. National 5 Exams.
