  One of the ways I use to check for a virus is to run CHKDSK and look at the
  total memory.  For a number of viruses I have seen, the normal number of
  655360 gets reduced to some other value. 
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.
