it only been weeks that i bought a new asus laptop. my friend plugged in his usb to show me some pictures and after viewing i shut down the laptop. that was the last time i could log into that laptop. eversince everytime i try to log into it, a message comes on-screen saying windows cannot log in to your user proflile. please enter your administrator password. the thing is i never set an administrator password. i dont understand is this a virus that got transmitted through the usb because my friend had the same problem in his pc. can anyone please help?

I'm sorry we can't give information on how to bypass security measures set up on any machine.
