TMC
It is a harmless memory resident partly encrypted parasitic virus. It hooks INT 21h and writes itself to the end of COM and EXE files that are accessed. The virus infects the files on floppy disks only. The virus checks the file names and does not infect the files: NO*.*, WE*.*, TB*.*, AV*.*, F-*.*, SC*.*, CL*.*, CO*.*, WI*.*, KR*.*.
The virus uses uncommon polymorphic engine - each time the virus installs itself into the memory it mixes blocks of its code and data and inserts random data. The virus also changes data offsets in its assembler instructions, constants and so on. As a result, the virus is not 100% encrypted, but it has no constant parts of code and ever the length of virus is changed.
Being installed into the memory the virus does not changes its code anymore, and all its replications have constant set of instructions. After reboot the virus installs itself into the memory and generates new set of instruction and infects files with this new set.
The virus contains the text:
