PS I just use Google a lot. I usally pick the number one and two post. Some times I get lucky and I do have a fair amount of knowledge with W7. I personally prefer MSE and Malwarebyyes running in real time.
I have no problem with a expert from this forum replying and agreeing or disagreeing with my replies. That's the way I learn new things. I have no ego, so please correct me when I'm off base.
Dokie!!
