That's a common symptom of the 1813 (or "Jerusalem") virus, one of the
most common PC-DOS viruses.  Have you used a virus-scanner on your
system?  If you *do* have an 1813 infection, the other symptoms that
you're seeing are probably due to various bugs in the virus and/or
"incompatibilities" between the virus and your various programs...
