doom.asm

More than 800 virus code (old school) just for fun and studying prehistoric viruses. WARNING: use

; VirusName : DOOM!
; Origin    : Sweden
; Author    : Raver
; Date      : 23/12/93

; My second scratch contribution to this issue. It's a simple non-over-
; writing, non-destructive exe-infector that "eats up" a bit memory on
; every run. It restore date/time stamps and uses an encryption routine
; to avoid discovery from virus scanners. Of'cos no virus scanners are
; able to detect it. This includes Scan/FindViru/MSAV/CPAV/F-Prot and
; TBAV's most heuristic scanner. Well, 9 out of 10 viruses, that's nothing
; but pure bullshit!, ha!, this "wanna-be" can't find a single flag in 
; this code!

; After these two moderate, educational viruses I'm planning to do some
; "fancier" memory resident viruses to the next issue. If I've got some
; time, that is. Fucking military service :)
