You said; ''I installed an unexpired virus software tonight, a firewall and Adaware. She had none of these when I started looking at it tonight. I ran all of these, but it did not correct the problem.''

If your mother's computer had no firewall, anti-virus, or anti-spyware options, most likely her computer is infected. Did the unexpired anti-virus have updated definitions?

You say it did not correct the problem, but did the anti-virus find any viruses?

A friend of mine running Windows 98SE finally installed a firewall, anti-virus, anti-spyware and anti-adware on his computer recently after 6 years, and immediately he installed the anti-virus, (AVG), it opened up with multiple virus warnings, and when he could eventually run a scan in Safe Mode, AVG found 1015 different viruses.

I'm amazed that he was ever able to startup the computer.
