There actually are three versions of nVIR.
One beeps, one says "Don't Panic" instead, and one kills an arbitrary
file in the System folder. This last probably never made it out of
Europe because the "Don't Panic" version is more aggressive and able to
install itself over existing versions.

This is the reason why the oft-mentioned procedure of "install INIT32
and nVIR 0..7 in your System" is dangerous.
All three versions, however, check for a nVIR 10 resource and
do nothing when it is present.

As far as I know, nVIR is currently the only virus for which an automatic
removal program is available (my "KillVirus" INIT).
