Best Free Antivirus For Windows Xp

Hello,
I have an old PC with Windows XP SP3 which I intend to keep because of some software that runs only on XP (I could use virtual machine but it would still need this).
Now what is the lightweightest and fastest antivirus which still supports Win XP?
I've tried a few, Bitdefender and Kaspersky, and they were really slowing down the PC (which is actually not bad regarding to components, core2duo e4600 2.4 ghz with 4 gb ram), and tried Baidu which worked fine but they stop updating it.
Now, according to this site, there exist at least 10 major AV providers that keep their suites updated to Win XP. Note: I only need basic AV protection (and free).
Does anyone have hands-on experience with an AV that is fast on Win XP here?

I am still using Windows XP Professional Service Pack 2 and I would like to know what would be the best antivirus for it. I have been using NOD32 for quite some time, but I couldn't find any more working serials on the net.
