Five hours and 2 scans later ...

I may have finally resolved my virus problem with the Anti-Malware program (Dick advised me there was a free version).

Two viruses/hinky stuff found after a nearly 2-hour scan. That scan followed a nearly 2-hr. scan by McAfee (which found nothing amiss).

I hope all this is helping others who may be having similar problems. I would advise everyone to check to make sure their anti-virus program is turned on ....
