I would start in SAFE MODE with networking.
Then, assuming you DID keep Malwarebytes since you removed AV Security Suite, I would update it and do a full scan.
Then I would go download Microsoft Security Essentials (From the microsoft website, mind you) and get that updated and do a full scan with that too, all while in safe mode.
If anything is found with either scanner, I would have both programs remove it, then Id restart the computer....
but thats just what I'd do.
Possibly admins have better advice than I do?
