I recently brought a second hand computer, and I've installed all the necessary Norton Anti-Virus programmes, plus SpyHunter, but I am being overtaken by a programme called AntiVirGear. Their Icon pops up all over the place, and each time I go into Internet Explorer it's as though I am being invaded. At the moment there is a window in the bottom right hand corner telling me that even this Helproom is a potential threat.
I've tried everything to get rid of it, but nothing works, and I'm wasting so much time.
I have even followed instructions, using an old thread here, but that only worked for a short time.
If someone could help I would be so very grateful, as I'm now left thinking that maybe it was the reason the person I brought it from knew it had this problem.
