THANKS to all of you for your replies and suggestions
I want to thank all of you for your suggestions and advise and importantly your experiences with the antivirus programs you have used.
I think because money is a factor at this moment and also I have found just yesterday that McAfee Security Center that I have been using was totally messing up my system that I am now downloading Grisoft AVG. I will give that a try for a while. Not so concerned at this time about tech support.
I have been having problems with my PC over the past 3 weeks or so and just couldnot figure out what it was. Now that I have completely removed McAfee my system runs much much better. Almost like it did before. Something must have become corrupt which cause my system to really get screwy. I had even reinstalled McAfee thinking that was the problem but did not make things any better until I completely removed it.
So for now I will try AVG and see how that goes.
Once again thanks to all of your for your help.
