Lemming

Threat description

Details

TYPEVirus

Summary

The first variant of this virus appears to have been written to force TBScan to use the DOS file system and ignore the contents of Anti-vir.dat. It is also known as the "Thunderbyte Killer" due to the text "The Rise and Fall of Thunderbyte-1994-Australia. You Will Never Trust Anti-Virus Software Again!!", but it also attempts to avoid detection by F-Secure anti-virus products and Norton Antivirus.

Lemming has been reported to be widespread in Australia.

There are few known variants.
