My daughter has an XP Home machine that is behaving strangely to the point that it is unusable. There are a number of symptoms including slow performance but one of the most annoying is that when she types a URL into IE she is always redirected to another Web site. My first assumption was a virus but she has a current version of McAfee installed. Any suggestions about how to diagnose and fix this problem? I realize I have provided very little information. If you need more details let me know what you need and I will try to get it. Thanks.
