Many stealth viruses can hide from virus checkers as
well as not showing the
memory they occcupy as used. When you ran the scanner did you boot from a
_known_clean_ write protected floppy, this is essential for reliable scanning.
Also, you do not say what virus scanning software you are using bear in mind
that MS anti virus doesn't detect many common viruses.
Yes, I booted from a write protected floppy, but before that I did a
virus scan with a normal boot.
And of course I don't use MS Anit Virus. IIRC, it hasn't been
updated since 1992 when Windows 3.1 shipped!
