I no longer have a Samsung monitor for my desktop, and when I start the computer it identifies the Magic Tune program, but when I try to delete it, it won't allow that function. What should I be doing?
Try using Revo Uninstaller. Even if it can't uninstall the application normally, it will force it to uninstall by wiping out all traces of its presence from the system.
After that, try running AdwCleaner to make sure that there are no leftover rogue registry keys or toolbars in your system.
