|Ok so I was just minding my own business doing some writing in notepad++ when all of a sudden the screen goes in front of me and a login box shows up in front of me and states that the system has been locked and that an adminstrator must enter a password to unlock it.|
My account was shown in the login credentials spot so I just entered my password for the account and it told me the password was invalid. Which it isn't. Caps lock wasn't on either.
Suddenly the thought occured to me that my computer might have just been hacked so I immideatly hit the restart button on the case, pulled the plug on my router and then waited to see what happened.
The computer started up fine and I ran a full in-depth scan with eset smart security 4 (using latest virus database of course), on th eboot sector, the operating memory and the entire C drive.
It found nothing. I looked at the event logs as well but none of them list any events for the period directly before I restarted the computer.
