westsunrise, now that you have updated to SP3 why not give avast another try! you might be pleasantly surprised 
If you check the sig’s of the other user’s you will notice that there are plenty of xp user’s with no issues, it pay’s to always keep your system clean with something like ccleaner and always updated with the latest from windows updates and any other programs you may be running.
