I have just changed my log on password for the only account on my computer. My account. I caught my brother surfing the net, not even on Safe mode, like he knew my password. But he couldn't have. So he was like, "I know how to get on your computer now". It made me really angry that this log on password stuff wasnt really working. Does anyone know if there are ways to get in without knowing the password? I want to prevent my brother of anyone else from coming onto my computer and by mistake, they put spyware on my computer and get some virus.
