Synonyms: VGA2CGA, Taunt, Hahaha.
|
||
|
||
Host Machine: PC compatibles.
|
||
|
||
Host Files: COM files.
|
||
|
||
OnScreen Symptoms: When activated, displays "Your computer now has
|
||
AIDS". The word "AIDS" covers about half the screen. Following display
|
||
of this message, the system halts and must be rebooted..
|
||
|
||
Increase in Size of Infected Files: n/a.
|
||
|
||
Nature of Damage: Overwrites first 13K of infected programs. Not memory-
|
||
resident.
|
||
|
||
Detected by: Scanv40+, Pro-Scan.
|
||
|
||
Removed by: CleanUp, or Scan/D, or delete infected .COM files.
|
||
|
||
The AIDS virus was first reported attached to a program called
|
||
VGA2CGA. It is known as "Hahaha" in Europe, and IBM refers to it as the
|
||
"Taunt" virus. When it activates, it displays the message "Your computer
|
||
now has AIDS". After the message display, the system is halted. You will
|
||
need to turn it off and reboot to restart it.
|
||
|
||
The only protection against the AIDs virus is full backups of your
|
||
.COM files. Written in Turbo C, it copies itself over the first 13K bytes
|
||
of a .COM file. The original function of the .COM program is lost, and
|
||
any other .COM files locatable by the program are also overwritten in
|
||
this manner. It evidently has a minimum size which it will not infect,
|
||
but it also totally loses all the data at the beginning of the programs.
|
||
Recovery of a damage program is not possible.
|
||
|
||
This virus should not be confused with the AIDS Information Disk
|
||
Trojan. See also the Lisbon virus.
