Query: The bad reviews are correct!!! Don't buy it!!!

Like many others, I purchased Norton 360 when my old 2003 Anti-virus stopped being supported. It does drastically slow down the PC's performance and web surfing. (FYI, my PC is a P4-3.0ghz, 1meg Ram, Win XP.) While I've not noticed any problems running the software (crashes, etc.) the dramatic change in performance makes me wish I hadn't purchased it.Also, it is very cumbersome to try and modify the advanced settings. If you change anything, your task bar icon stays in the "troubled" mode making it seem like your computer is always messed up.Don't buy it, looks else where...I'm uninstalling it and going with McAfee...
