Some XP users have seen this issue you are having. Some tried to just run System File Checker while others use A-squared to remove the malware and the error goes away. Give it a try.

I have Windows XP and despite ESET-NOD32 and Anti-Malwarebytes I have a nasty and persistent virus called AXWIN Frame Window-svchost.exe.-Application Error. Can anyone tell me how I can get rid of this thing. I'm desperate. It has had me crippled for more than a week.
