Mzee, You really need to get an antivirus / antimalware with active shield for your PC... You can not do passive scans after the fact. Google free Avast, free AVG, free Avira, etc. Even basic Microsoft Security Essentials is better than nothing. Malwarebytes is highly recommended around here as well but you probably need to get full / paid version with active monitoring component. Sorry, this is a bit too late to be helpful but at least gives you some future direction... I do not even want to comment on saving your important credentials on email servers (especially public ones).
