Started my PC this morning and my Windows 7 Pro login password had been changed, with the hint changed also to: ha ha .
I do not do anything online to provoke malicious behavior from ppl, how did they get in?? I am running MS security essentials on this PC as well. The only use this particular PC has is for watching TV channels online. That's it, nothing more.
Furthermore, I only plug my router in when I am home, leaving no connection availible for most the average day.
I am really boggled here, any advice or idea's on how this happened would be appreciated.
