Hello all. I have been having some serious issues with what I believe to be malware/malicious software on my computer. About a month ago my WoW account was compromised (hacked), and I received warning saying that my gmail account had received suspicious log in attempts. After running scan with AVG and MalwareBytes, both yielded nothing, so I decided to do a clean install of windows for a guaranteed solution (my computer is very new and I mainly just had WoW, Skype and Ventrilo installed, so it seemed like a relatively simple solution.)
Well yesterday I wake up to find that my account had been hacked again. I might add that I have a mobile authenticator, and somehow this is still happening. Anyway, I perform an account recovery and get back my items/characters and begin to perform more scans. I used AVG Free Scan, Spybot Search and Destroy, Super AntiMalware, and Malware Bytes. Every single one found no threats. I also downloaded HiJackThis and posted my logfile on Tech Support Guy forums yesterday, but no one has responded. Anyway, today I receive another e-mail from blizzard saying that multiple individuals have provided sufficient evidence that the account belongs to them, and that they are locking my account until they are able to determine who the account is properly registered to (me.) So I am kind of in a panic.
The main parts that confuse me:
How was my WoW account hacked through an authenticator?
How did the malware seemingly persist through a complete reinstallation of Windows 7? Or did I somehow procure the malware again?
And of course: how do I get rid of it if nothing seems to detect it??
Anyone who can help I would be so grateful, I have no idea what to do at this point.
