Sorry, for some reason, I'm not getting notice of replies. I now use the paid version of AVG and have been very pleased with it. I used eTrust AV from Computer Associate for many years, but they insisted I get their security suite when renewal time came up and billed me for it. I don't do suites. Unfortunately, as some the these companies grow, their whole attitude changes!
I don't use any of the security programs offered by Microsoft.
