The Ghost viruses (both boot and COM) were discovered at Icelandic
|
|
University by Fridrik Skulason. The Ghost COM virus infects generic COM
|
|
files, increasing the file size by 2,351 bytes.
|
|
|
|
Symptoms of this virus are very similar to the Ping Pong virus, and
|
|
random file corruption may occur on infected systems.
|
|
|
|
The Ghost COM virus may be the first virus to infect both files (COM
|
|
files in this case) and boot sectors. After the boot sector is infected,
|
|
it also acts as a virus (see Ghost BOOT virus).
|
|
|
|
To remove this virus, turn off the computer and reboot from a
|
|
write-protected disk. Then use MDisk, NDD, or the DOS SYS command to
|
|
replace the boot sector on the infected disk. Any infected .COM files
|
|
must also be replaced with clean copies.
