Been using AVG for years and like it Other good free stuff out there too, like Windows Defender and Spywareblaster. I also like the Secunia site for the free scan which tells you if any program needs updating and where to go to do it.
I had the same problem with Norton, so I swithched to Avast. I had problems with Avast too. It seemed to conflict with my Outlook. If I opened my Outllook before opening Internet Explorer, everything will freeze until I close Outlook. I liked Avast, but it was a pain in the *** to deal with when my computer would freeze. i guess I am going to switch to AVG. Does it scan incoming email?
