AVAST COMPATIBILITY WITH XP

I have paid licenses for both Avast Pro Antivirus and Avast Internet Security. Still I have here some computers running Win XP that for tactical reasons have not been changed to newer versions.
Those computers run also a paid version of McAfee antivirus that is high resource demanding. I was thinking to remove McAfee and install one of my two AVAST versions.
My question is, are those AVAST versions compatible with XP ?. Can I select to download a specific AVAST version for XP, or the default will be OK ? . All XP PCs have 4MB RAM.
Thank you for your help.

yes the standard version supports XP SP3. we don’t have any special version for XP.
4MB of RAM? I hope you meant 4GB :wink:
