I have to back up Gamer420 on this one.
I have personally had to REMOVE McAffee and Nortan AntiVirus from over 3 pc's and 5 laptops.
Reasons?
McAffee-Gives you ads for McAffee, the computer it was running on had 4 viruses, the other computer it was running on had 2, and you have to pay a subscription for it. Takes a long time to finish scan... people who had it didnt even try anymore.
Nortan Antivirus- ALMOST impossible to shutdown/turnoff without logging into it. It just REFUSES to let you uninstall it unless you log in, dance, stab your sister in the eye and praise satan. Also subscription based, also slow scanning, and out of the remaining 6 computers I had to uninstall it from, 3 had at least 1 virus on it. One of those computers had SO MUCH SPYWARE that you could not START the operating system without safe mode.
Neither protects from spyware or even viruses, both have their own quirks.
Suggestion:
1. Use
Spybot S&D for spyware.
2. Use
Adaware SE Personal for adware (free version).
3. Use
Firefox. Please. Dear God please. OR at least IE 7.
4. Use
RegScrub XP to clean your registry after deleting all this crap to prevent problems.
5. Use
AVG free virus scanner: Fast, easy to update/use, easy to remove if you tire of it, and you can make it ONLY RUN ONCE A DAY, so that it doesnt constantly drain your resources.
6. Use
O&O Defrag Pro (free trial works great), it can defrag your computer completely with one pass, even if your hard drive is 98% full already. Defrag using ANY program that also does space defragmentation (O&O does that), so that the next thing you download doesnt get split up like swiss cheese.
7. Use
FreeRam XP Pro, or some other high quality ram cleaner. This will run in the background, and if your ram drops below a certain amount (and you are not doing anything processor intensive or memory intensive), it will compress, clean, and move things from your ram into your virtual ram to keep your computer responsive (Imagine rebooting your computer without restarting).
Other than that, I got a whole bunch of other neat stuff, but those 7 things are almost REQUIRED on XP to ensure usablility.
