Threat description

This is one of the largest viruses known, 5120 bytes. It will infect both .COM and .EXE files, selecting one file of each type to infect, when an infected program is run. Parts of the virus seem to have been written in a high-level language, probably compiled BASIC, but the initialization code appears to be written in assembly language.

Several variants are known, but the differences have not been fully determined.
