I moved this to Malware Discussion > Home User Assistance although I'm not positive it's actually malware, but certainly a nuisance a.k.a. a PUP (Possibly Unwanted Program)
If it's listed in your Control Panel > Programs then uninstall it.
Look in the last link below and run Stinger, Malwarebytes Free and perhaps also AdwCleaner.
To keep Malwarebytes actually free of charge do NOT accept the free trial.
