If you find after running AIMFix that you still experience some of the symptoms above, you may want to run AIMFix in Windows
Safe Mode or run a full-fledged virus\spyware scanner as you may have something other than AIM specific malware.
Hopefully with these hints you’ll be back up and running in no time!
