-
- 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.
