Avast Older Version 11.2.2262 safety today and updates

Good evening. I have Windows XP but without Service Pack 3. I downloaded an older Avast free antivirus version the 11.2.2262. Does it protect me from viruses? Does it takes updates?

Like XP SP2, Avast 11.2.2262 is old. Whilst it may have current virus definition updates, but that isn’t everything as new modules/functions aren’t included.

Old programs can be vulnerable to exploit and AV programs are no different as the old program in itself doesn’t get updated. So any vulnerability would remain as companies only update the current product/s and not historic versions.
