Does MSE not work as well with XP? I ask because I had it on my XP system, but a short while later noticed that it wasn't in my system tray anymore and had been disabled. I ran Housecall and CCleaner (including the registry cleaner), but MSE wouldn't reinstall. I've tried several other AVs since then, and they all installed without a problem.If you're using MS Vista/7 then you probably can't go too far wrong with Microsoft Security Essentials.
I going to hazard a guess and say, "probably not"! M$ isn't really supporting XP, or maybe only supporting it half heartedly. That said, M$E should be used with the other free components of M$ security, "Windows Defender" and, "Malicious Software Removal Tool". Also keep in mind, the firewall in Win 7 is much more competent than the joke of the same name in XP.Does MSE not work as well with XP?
