Cannibal Virus- This virus is known to infect COM files, but unknown variants may infect other items as well.

Darth Vader Virus-  This virus is known to infect COM files, but unknown variants may infect other items as well. It remains resident in memory and infects/damages its victims in the background. Unusual messages or effects may appear on the screen.

Doom 2- This virus is known to infect COM files, EXE files, but unknown variants may infect other items as well. It remains resident in memory and infects/damages its victims in the background.

Doomsday 2-This virus is known to infect COM files, but unknown variants may infect other items as well.

Friday the 13th- Tthis virus is known to infect COM files, but unknown variants may infect other items as well. Actually, this is not just a virus, but a class of viruses. They are all created with the same tool. It is hardly possible to divide and describe all viruses created with this tool individually. Be aware of unknown side-effects. It is highly recommended to restore all files from a reliable backup. Because the source code of this virus is widely spread, there are many variants of this virus. It is hardly possible to divide and describe all variants individually. Be aware of unknown side-effects. It is highly recommended to restore all files from a reliable backup.

Hell Raiser- This is NOT a virus, but is detected as such because it has been identified as a virus by some independent tester and is being used in virus scanner tests. To avoid an undeserved penalty in such tests, TbScan detects this file too! As new variants of existing viruses appear almost daily, it is possible that you will encounter a variant of this virus which will still be identified by our scanner, but behaves differently than described above. The information above is therefore intended as a basic guideline.

Nata 4746- This virus is known to infect COM files, EXE files, but unknown variants may infect other items as well. It remains resident in memory and infects/damages its victims in the background. The virus is polymorphic, which means that it looks different each time it infects a file. Some anti-virus products may have difficulties detecting this virus reliably. Also some false alarms may occur, especially on non-executable files. This virus has 'stealth' capabilities, which means that it is able to hide its presence from most people, and even virus scanners and checksummers, unless the virus has not yet been loaded in memory. It is highly recommended to boot from a clean diskette before scanning or cleaning! Unusual messages or effects may appear on the screen. This virus is very obvious, and it is therefore extremely unlikely that the virus will succeed in spreading unnoticed. If you ever get it on your system, it has probably been put there intentionally! Anyway, you will find out that you have a virus immediately, even without a scanner.

IVP(2)- This virus is known to infect COM files, EXE files, but unknown variants may infect other items as well.

Orion 262- This virus is known to infect COM files, but unknown variants may infect other items as well.

Warp Virus- This is not a virus but a Trojan Horse. It does not spread but simply causes damage. Determine the source of the file and simply delete it. As new variants of existing viruses appear almost daily, it is possible that you will encounter a variant of this virus which will still be identified by our scanner, but behaves differently than described above. The information above is therefore intended as a basic guideline.
