Wasp_II.1312

Description Wasp_II.1312

It is a very dangerous nonmemory resident parasitic virus. It searches for .COM files in the directories marked in PATH, then writes itself to the beginning of the file. While infecting a file the virus creates the temporary TMP.$$$ file.
Depending on its counter the virus patches the C:IO.SYS file, it writes the string "Fucking" to the block of messages of the IO.SYS. The virus overwrites the boot sector of the A: drive with the text:
I'm W.A.S.P.
Fuckyourself !

The virus also displays the messages:
Insufficient memory
Incorrect DOS version

It leaves a small memory resident program that "shakes" the screen. The virus also contains the text strings:
W.A.S.P.
PATH=
c:io.sys *.com
tmp.$$$

MF family

Description MF family

These are dangerous memory resident polymorphic and stealth parasitic viruses. They hooks INT 8, 16h, 21h, 2Fh and write themselves to the end of COM and EXE files that are executed or closed. On opening an infected file the viruses temporary disinfect it.
Depending on their internal counters the viruses change several extended ASCII (cyrillic) letters on the screen. The virus also changes letters that are typed by keyboard.
In 14 minutes after installing memory resident "MF.3564" displays the text "Merlin from AMBER: FUCK YOU MAN!", in 40 minutes the viruses corrupt the CMOS memory. Depending on a random counter the viruses disable accessing to remote disks and files.
When the text "Tell me your ver, mf!" is entered as a DOS command, the viruses display:
"MF.3490": My ver is MF v10.1
"MF.3564": My ver is MF v10.0

When the text "Do your job, mf!" is entered, they display:
Yes, I got it, man.

and then corrupt the CMOS memory.
