Have had alot of problems with my computer lately. I had mcfee as a virus protector, but everytime it upgraded I lost all my files, e-mails, and bookmarks. Obviously something that I did to retreive these messed up my ability to "chat". I did a system restore, and deleted mcfee and also google. Would that make a difference?? This is so frustrating - I did find so much help and no longer have access to it. Have talked to Dell, Microsoft, Mcfee and am out of ideas.
