I always felt MSX needed a good virus 
Makes it look more important 
It seems, that TCAV is dissappeared 
FYI: If you need to use unzapp, delete all backup copy of viruses right after unzapp (*.inf), execute CHKDSK /F and delete *.CHK from root directory. This is ugly way, but it works.
NYYRIKKI, I have TCAV on my HD. Are you still in search of this util? I can send you the tool (without the virus ) Sorry, I haven't seen your request earlier.

Well guys, let's face it: it is the existence of viruses that distinguishes the platforms — the "mere" 8-bits from the "real" computers. One that can't reasonably support a virus just can't be taken seriously enough. And it is also a sign of survival level of a platform — I haven't even heard of an antivirus program for an Amiga for years (not to mention Atari ST). I even tried to write a virus for a Sam Coupé, in the Sam Basic, which was just ideal for such a thing, it had a command which could write and execute program lines but I didn't have enough time to finish the project... (Am I too twisted?)
Well.. There was another, unreleased, MSX-Virus
The FAF (Federation Against FAC) made a boot-sector virus, which, after the reset of an MSX, would only allow you to type "FUCK FACK", no matter which keys you pressed.
Every floppy-disk insterted that would be accessed in some way, would be scanned to see of sector 0 was a standard boot-sector or not.
If it was a standard boot-sector, it would write the virus to the bootsectror. Disks with a special bootloader or so would not be infected this way.
Never released it though
LOL @ FUCK FACK 
btw:im glad i never had a virus myself
