First, thanks to Styx, Clifh and AnnMarie for their suggestions. I downloaded AVG anti-virus and may use that - but there are some secondary programs with Mcafee that are helpful, so, I am thinking about it.
Secondly, I ran msconfig as suggested by AnnMarie and unchecked the spyware that was causing the pop up - and now no more pop up.
Lastly, Cliffh was right - it was a Sony VAIO component and I will use his suggestion to review that. Although there are some other - similar sites, in my opinion, this site is the most helpful of its kind on the internet.
Thanks again, Nor,69
