this does not mean that the virus would be activated just by sticking it
into the floppy drive. The virus protection software you are running is
running all the time i guess (background in windows, and as a TSR in dos),
and when you stick the disk in the drive and the boot sector is read, the
virus protection detects the virus in the disk.
The virus does not need to run for the virus protection software to detect
it (in fact, if it runs, it's too late). Try the experiment. grab an old
hard drive you don't need, stick the disk in the floppy, take it out, and
then check if the virus is in the hard drive. I bet you 99-1 that it is

i think that the stealth virus you've got is a boot sector virus, but
AFAIK, not all stealth virii are, by definition, boot sector virii.
