Normally when I boot the computer up, I am presented with the login screen where I am asked to enter a 4 digit pin in order to login to windows.
but today when I boot up those things happend:
Normally the screen that I will first see is this: Image
but now what I saw was a blue background like this: Image
Sometimes when I boot up the computer its automatically telling me that I had too many wrong attempts and I need to write the password A1B2C3 to continue (and I didn't even did enything)
Insted of getting the screen that asked me to enter the PIN I got a blank screen (not sure about the color) and a cmd window that looked something like this: Image
I enterd my PIN because I was very confused but now I think it was a mistake...
And after this everything was normal
Is this normal or a virus?
(sorry for my bad English)
