PMM.575

Description PMM.575

It is a harmless nonmemory resident parasitic virus. It searches for COM files, then writes itself to the end of the file. The virus contains the text string:
*PMM r1.0*

That virus uses quite interesting mutation routine. That routine scans the code of the virus, disassembles the instructions, and replaces some instructions with their "synonyms":
XOR Reg,Reg -> SUB Reg.Reg
MOVSB -> MOVSW
MOVSW MOVSB

and so on. As a result, the virus is not encrypted, but in different infected files the code of the virus contains different instructions.

PMT.867

Description PMT.867

It is a harmless memory resident encrypted companion virus. It hooks INT 21h and creates companion .COM files while executing EXE files. The virus contains the text strings:
