OK, this is obviously Windows 10. In my opinion for the average user, your best bet is to click start and type 'Reset this PC'. Feel free to keep your files in this case ~ I believe it wipes out %temp% and %appdata%, which is probably where the virus lives, but probably delete everything out of your downloads folder without prejudice.
You'll need to reinstall your games, your MS office and any other registered software - install your steam client your battle net and what nots, and then have fun. Just my opinion on your quickest, safest, easiest route back to good health.
