I ordered the keyfob authenticator today. My PC is clean, I fix and clean peoples computers for a living. I don't go on diablo sites except for battlenet itself. The whole thing seems fishy to me.
My account was hacked while I was playing it last night. Hit my high level character and wiped out the stasch and my gold, but left what I had equipped. Probably because I was changing the password as fast as I could.
