By allowing the wrong download to happen (my error), I ended up with Cloud Scout and Movie Wizard malware running in Firefox. Movie Wizard was the only one of the two programs showing up on the program list in Control Panel, but after many tries, it would not uninstall. I finally found the program folder for it and simply deleted the folder. So I now get no ads, BUT an empty CloudScout frame is still in almost every Firefox tab. The biggest problem is that after about 30 seconds, every tab starts reloading again and says "connecting" it seems to just be trying to open a new ad and it cannot, so the empty frame remains. I have tried to "recover" windows to an earlier date, but the only one available would not "complete". I reset Firefox, which made no difference. I deleted, restarted the computer and then re-downloaded Firefox, these actions changed nothing related to this problem.
