Description Seagull.448

It is a dangerous memory resident parasitic virus. It copies itself to the memory at the address 9000:0000 and does not fix MCB list, that may crash the system. Then it hooks INT 21h and writes itself to the beginning of .COM files that are executed. It decrypts and displays the string:

Beavis.655

Description Beavis.655

These are not dangerous memory resident parasitic viruses. They copy themselves into Upper Memory Blocks, hook INT 21h, then they write themselves to the end of EXE files that are executed. Depending on the system timer these viruses display one of the messages:
FIRE FIRE FIRE!
Hey butthead this sucks change the channel!
Shut up butthead or I'll kick your ass!
We're there dude.
The Beavis virus kicks ass!

Bebe.486

Description Bebe.486

These are nonresident dangerous viruses. They affect .COM-files in the current directory. They increase the size of infected file up to a paragraph, copy themselves at the file end and alter its first 14 bytes (PUSH AX; all ; JMP FAR Loc_Virus ). The viruses have an error - doesn't restore DTA. This might result in hanging up the computer. There is one more delicate error: they doesn't take into account that INTEL 80x80 processor has a conveyer, and modifies the command following the current one, the result is that the viruses work only on old IBM PC models. Apart from the above text the viruses contain the string "*.COM".
The viruses are nonresident, but they create a small memory-resident program. With this purpose they copy a part of viruses' body to the interrupt vector table at the address 0000:01CE and sets INT 1Ch or INT 21h to this program.
"Bebe.486" hooks INT 21h and while writing into file (INT 21h, f.40h) it changes '+' to '-' and '-' to '+' in buffer is writing.
"Bebe.1004" hooks INT 1Ch (timer) and some time later displays the following message:
+-------- VIRUS ! ------+
ƒ Skagi "bebe" > ƒ
+-----------------------+

After the word "bebe" is typed in from the keyboard, the virus answers: "Fig Tebe !".
