Guys, Don & I both use avast. It's reporting everything as a virus. Don't panic if you see this. It seems their latest update had a bit flipped and reports everything as a virus. By tommarrow i suspect a patch will be live for now ignore the popups or simply uninstall avast and wait for update. Might want to install something else in the interm. This one really screwed the pooch. If you let it quarenteen it will break every app on your machine.
