I cannot permanantly remove an add-on, even after troubleshooting.

I have been having difficulty deleting an add-on that I did not install in the first place. It is called "Plus-HD-1.2 0.93.199", and claims to be an extension that automatically sets YouTube videos to HD. It does not do that, and instead waits in stasis for a while and then turns random couplings of words into green links to who-knows where (I have not clicked on any in order to further prevent other problems). I figured out it was this add-on specifically by noting that I never installed it, combined with the fact the green links stopped after I disabled it.

I have tried all of the troubleshooting steps listed in the main sections devoted to clearing unwanted add-ons, as well as using my antivirus browser cleanup and completing a system restore to the furthest possible point. The only thing I have yet to do is reset my Firefox browser to original settings. No matter what I do, the add-on bypasses the blocking of unwanted add-ons, reinstalls itself, and turns on after every shutdown. I know that I was not the one to install it, because if I want a YouTube video set to HD, I set it to HD myself.

Please, what do I do to get rid of this? Is this a problem for anyone else?

Extensions that do not have a "Remove" button are installed by other software and are not under control of the Firefox extension manager. Such globally installed extensions are usually found via a registry scan or are installed in a location that Firefox scans for installed extensions.

Extensions installed this way need to be removed via the settings (options/preferences) of the program that has added this extension or you need to uninstall this program via "Control Panel > Programs".
In Firefox you an only disable such an extension.

You can check in "Windows Control Panel > Programs" for recently installed programs to see if any suspicious software shows up.

Thank you very much! That seemed to do the trick.
