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.

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: Anke Huber for Ever "-=_ AP.CC.DV.EV.DF.T2T.TC.M.SR.RA _=-" Fuck John McAfee Eat my Butterfly Suck her Spinkta muscle Bruce Sterling; I'd like to shove ya texan accent down ya throat Oprah Winfrey sings ACDC's classic PMT I've got PMT PMT I'm dynamite PMT But I'll win the fight PMT I'm a powerload PMT Just watch me explode The funky dyin' brain cell CRYPTO-KING v1.0
