So, for starters, my mtgox password is something I ONLY use for mtgox.
My Gmail was already locked down (supposedly they're doing this to everyone on the list as a precaution).
I just tried to post on a Facebook wall though and got this message from FB:
Account Safety
It looks like a link you pasted into your address bar caused unintentional activity on your Facebook account.
The link may have looked like this:
javascript:(a=b=document)...;void(0)
Don’t worry, your account is safe. In the future, never paste suspicious-looking links or text into your address bar. They could cause spam on your account.
If you did not intend to do this, please click Cancel.
Is this related? I'm on Chrome/Win7 if it matters. Just ran full virus scans yesterday w/ MalwareBytes and MS Forefront.
