Any one that works.

Norton, McAfee, and many others work just fine.

I personally use AVG as it's free for home use.
The best antivirus is windows antivirus that is part of the windows xp operating system and some common sense.

Don't open up downloads from emails - even from your friends (they may not know they have a virus). Do not click links from emails.

If you decide that you need one anyway (although I can't see why), use norton because it uses less system resources. McAfee is a HOG! Do not download any spy sweepers either as they take up your resources too and you computer will run S L O W L Y!
It's a matter of opinion. I like the "anything that works" answer.

My best tip is just make sure you update it almost daily to stay on top of the latest signatures. I'm amazed at how many attacks

I've intercepted by doing this.

I ran the free version of AVG (Grisoft.com) on the last computer and now this one has McAfee on it. Both seem fine.
