I'm getting a black screen

[Harsun]

I downloaded avg network security software to check for viruses. After the scan was completed my files were not opening properly, it loads for a while and gives a error message. My computer feels very slow and I can't open any file or application. I tried to google the error code and watched some YouTube vids, it says to open comand prompt but I can't it's loading for too long and shows error. I even tried run as administrator but it's not working. And when I select restart or shut down it load for a min and shows a black screen with my mouse. I can't do anything pls help.

just hold the power button on case until your PC shuts off. Though i would also advise to be cautious about that simply because it seems you have run into some other issue regarding your whole OS.
