-
- 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.
