Avast free quit working on my 8.1 computer. So I reinstalled 2015. Nope. The icons just sit there, can't open them. Simple, go to control panel and uninstall. Whoops. That started, but quit responding, and the window is now stuck on my screen. End task doesn't help. How do I get rid of it? The goal is to uninstall and start over. Will doing something in safe mode solve the problem? I'm lost, as usual.
