So I figure myself to be quite computer literate type of person, considering I am using the Linux partition of my laptop to post this.....

Anyways! I come home from work today and boot my laptop up in windows and find out that something is not the same as I left it. Anyways, I get a pop-up that fills the screen that poses as "Windows Security Center" and it says it is updating. Following that it gives me a 1900 number to call with a pin to enter. The number being 19009508477 with the pin being 315231. The window will not close on CTL ALT DEL nor will it close with a ALT F4. I'm at a loss of what to do. It is obviously not Windows updating something. I normally do leave my lappy unlocked so that my roomies can use it as they don't have a computer but honestly, I've never had a problem like this.

I do have a limited amount of time after starting up the computer to get a window/program of my choice up and running. But idk if my antivirus programs will cut it.

p.s. off back to the terrible windows land to see if I can resolve this problem!

please help!
