Summary of problem: my Hotmail and/or Gmail password keeps getting hacked even though basic anti-malware scanners say I'm clean.
Background: Couple of months ago my Hotmail and Gmail accounts were hacked. I scanned using half a dozen of different programs (PrevX, Spybot, Malwarebytes, etc.) but didn't find anything. As I was still using shared passwords at the time and my Hotmail and Gmail were linked to each other as security backup addresses, I figured one of them must have been leaked. I switched to unique passwords, cleaned out all the emails' security options and carefully declared myself 'safe' again.
Until this morning when my Hotmail/Gmail were hacked in the exact same fashion (the fake 'security email address' added was similar and they once again went after my World of Warcraft account). Scans once again show nothing, but an hour later after changing passwords there was still evidence of them having limited access.
Question: Is there any way to more thoroughly check my system? Thanks in advance
Edit: I run Windows Vista, 32-bit.
