I installed the program a couple days ago and switch from Norton to this program because many review says this was better and uses less resourcse. The startup time is longer than Norton Internet Security 2006. I read reviews about the program that the boot up time is quicker but my computer hangs for like 3 - 5 mins, Microsoft automatic update crashes at startup, and then starts moving again. After a couple of hours at the computer, my system becomes to act strange, I open winamp and it crashes, open up the windows firewall and it crashes. Is it me or the program because I want to uninstall the program and return it for another antivirus + firewall software.
