I have a floppy disk in hand with a benign Stealth C variant virus. In order to
get your virus protection software to go all bongo over this virus on this
floppy, all you have to do is stick it in the drive. Do nothing else. You also
do not need to be in Windows for this to happen. It does the same thing in DOS.
I have tested this myself, as I keep the floppy as a good way to safely test
antivirus software installations with real virii that do no damage.

BTW, if you want a copy of this virus, all you have to do is exchange files over
the internet with anyone on a PC at Sturm Ruger, Inc. Their entire network is
infested with it, or was the last I heard. Be sure to have your antivirus
software on when you receive it.

I was under the impression that the Stealth C variant virus I have on a disk is
a boot sector virus. If stealth viruses are not boot sector types, please let me
