To tell you the truth I have been underwhelmed by the most common commercial offerings for Windows XP so far. I've never been in love with Symantec / Norton or with McAfee to begin with. But, man, they really seem buggy, or at least recalcitrant, when operated under Windows XP. (Yes, I'm talking about the latest versions, corporate AND consumer.) However, I can't actually speak authoritatively about them since I'm so unhappy with both companies that it has been a long time since I've installed them on any of my own machines. That means that the machines I see that are misbehaving when running them are systems whose installation and configuration histories are largely unknown to me. So, the misbehaviors I'm seeing could be caused by something else on those machines. Nonetheless, on the machines that I've examined that were misbehaving, replacing Norton or McAfee with Kaspersky (AVP Pro) has solved the problems we were seeing. I've also installed the freeware edition of Grisoft's AVG on several WinXP systems. It doesn't have the reputation of the aforementioned software for detection rate, but I've used it on my non-critical systems at home and never had a problem either with AVG itself or with any demonstrated lack of ability to detect malevolent code. It works well, and a system that runs it should be reasonably safe, as long as the user is abiding by a few simple cautions.
I think anti-virus programs should be good at detecting viruses. But they should also not cause problems of other kinds.
You can get pretty good data on your options at

http://www.wilders.org/. A lot of anti-virus software isn't up to snuff in WinXP yet. Although you have to find AV software that works in your OS, that software will also have to suit you and the way you work with your system. So I don't think anyone else will really be able to answer this question for you. I'd suggest checking out those links and making an informed decision for yourself.
