What virus software is best for Windows XP

Thanks for your suggestion.

The reason I need to switch, is Microsoft Essential Security has quit working on Windows XP.

Thanks for your response.

Try the following Microsoft free Software, which detect & remove all known viruses from PC.

Why you're switching from MSE?

Malwarebytes.

I have Windows XP my Microsoft Essential Security needs to be replaced.  What is the best anti virus software for Windows XP.  Thank you

You can only install one real-time AV product; so you’re obviously better off if you pick one with a good protection rating – like the ones suggested above by Bruce Hagen. But you shouldn’t stop there if you’re using your XP computer for surfing, because the odds are going to be stacked against you in a big way. To stay safe, you’ll need to double-check frequently by scanning with some of the on-demand malware-removal tools suggested by quietman7 MS MVP here:

Supplementing your Anti-Virus Program with Anti-Malware Tools.

On my XP machine, I use Avast Free for the primary protection, and then back that up with the free version of HitmanPro (not activated) and HitmanPro.Alert (with CryptoGuard). I also do periodic scans with Malwarebytes, SuperAntiSpyware, and Kaspersky Security Scan – and I still back up all of my personal files religiously; because with a zero-day threat, everything else can fail.

[EDIT]

Looking around a little, I see that quite a few free AVs (for Windows XP) now tend to get better reviews than Avast, including these:
