I did a google search for "how to remove scorpionsaver" and found a good video and other good sites...
You have to uninstall it,
then check your start up programs (disable and delete it if there),
check scheduled tasks (disable and delete if it's there),
check extensions / add-ons for all browsers you use (disable and delete),
check the Program Files folder and make sure there are no folders for it,
remove it from the Temp folders and/or run CCleaner (both the cleaner and the registry cleaner).
Also check for these items when you're checking for ScorpionSaver:
LyricsSay-1, LyricXeeker, HD-Plus, Browse2Save, WebCake 3.00, DownloadTerms 1.0, LyricsBuddy-1, SuperLyrics-1, ElectroLyrics-1, a2zLyrics-1, SimpleLyrics,1ClickDownload, Superfish, Yontoo and FBPhotoZoom.
You can probably find the same video, it was one of the first hits in my search.
