K just did a quick scan with Windows Live OneCare and it didn't find anything.
I'm going to start the malwarebytes one now.
Here is my issue:
I have had some issues recently with my battle.net account. My password keeps on getting changed no matter how hard I try to protect it. I added an authenticator and my password still keeps on getting changed. I havn't told anyone my password.
Try to change it from another computer (preferably one on not on your network) and then see if it still happens. I'd also suggest changing your email password if you haven't done so already.
Of course, after you change your password from the other computer try to avoid logging in from your computer for a bit to see if it still gets changed.
I don't think I'm dealing with quite the same pressures though, at the very least its a significantly smaller system. For the time being I'm just going to put together a quick scrubby box though and hope it works good enough to not make my house toxic
I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
