For this kind of question it would have been better to post in the Windows-Virus & Spyware Problems forum. Have a look at my post in this thread http://forums.afterdawn.com/thread_view.cfm/260908 Just so as to make you know I have been using AVG moreso recently after being converted by my AD family. You can actually run the free version of AVG and the 1 year trial version of etrust's Ez antivirus simultaneously and see which you prefer at no monetary cost to you. I agree with Phantom. Norton's is really bloatware which 'hogs' you RAM and costs more than other competing software which are either equal to or even better in their antivirus protection.
