Excellent idea, you're lucky the bluescreen was the only problem you're getting. I've killed the ntldr on a couple occasions as a result of installing Symantec 7 with other things. Too many AV is a very very bad thing especially when you are running large scale ones like symantec. They like to dig their claws into your operating system more than a million virii put together. I work on a very high traffic ISP network and all I run is AntiVir (free-av.com) and and Microsoft AS Beta, I run scans with Microsoft AS Beta, AntiVir, S&D, Adaware, and HijackThis, plus whatever else if I get something that I can't get rid of, but I only run AntiVir and the Microsoft beta all the time.
