You know.. I don't know what is going on.. but my account security has been on my mind as of late as well.

My WoW account hasn't been touched.. but I've had several other account (mostly Gmail) accessed by a third party. My passwords have all been very strong, and very different. I think the only reason my WoW account has been safe is because of that there authenticator thingy. I ran the same software as you and come up clean, but accounts keep getting accessed. (Post-Password change).

I spent the entire day yesterday creating passwords so random, and unrememberable I had to write them down in my own little book thing. Swear to god, it better be good enough, or I will find this person and castrate them.
