Best antivirus for Windows XP? | TechPowerUp Forums 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 So I uninstalled Avira and now I am using Kasperski 2013. Is this antivirus good for my XP? If not, what else would you recommend?
