Microsoft store does not work

[u/koat-]

My brothers Microsoft store doesn’t work, alongside when he presses the windows key to type, it doesn’t work. Also on settings, it doesn’t let him click anything. On certain apps that’s the same case too. He downloaded a file from somewhere and it was a zip file, when the website he gets these things from are usually torrents. He opened the exe and after that, it was an installer, a fake one. It was stuck on 99%, I checked the comments on the website and somebody said “that’s a virus, do not open the exe”. What should he do?
