hey, hopefully the guide from ronintexas can help you. But if you can't still get rid of this groovorio.com, you can watch this video guide on YouTube
Thanks but I tried all the videos and no one had the correct answer. The only way to get rid of it was delete Firefox, remove all User/appData files of Firefox as well as all Program and Program Data files then run ad removal programs. There were no registry traces of it after all this was completed and problem was solved. Thanks for your input.
