Long time no see, MBox forums.

I recently tried to log into my BNet account to add a Diablo 2 CD-KEY, and had found that my account was gone. This concerned me as it had 7 WotLK boxes on it. I hadn't accessed it for around 1 year.

I called tech support and the guy was incredibly empathetic and helpful. He informed me all my accounts had had their 7-day free trials used up and were banned for accessing too many nodes in a given time frame (harvest botting).

He suggested I scan my comp with Malwarebytes. It found...........TROJANS!

I suggest you do the same to your comp. Good Luck with this.
