Virdem

Threat description

Details

Category: Malware
Type: Virus
Platform: W32

Summary

This virus was written in 1986, which makes it one of the oldest viruses in existence. It was written by R. Burger, the author of "Computer Viruses: A High-Tech Disease". It is not a threat in unmodified form, as the virus makes it quite clear that the program has been infected. Virdem overwrites the first part of the program and appends the original code to the end of the file. Two similar variants of this virus are known - one with all the text strings in German, but the other is an English language version.
