I have used many virus programs, the likes of Sophos, Norton, McAfee and am currently trying to use AVG. The only problem is that no matter which one I use it automatically closes down after a certain amount of time with no warning, especially when I am doing a virus check on the whole of my system. At first I thought it was the virus checker itself but after trying many different ones I am pretty sure I have a virus infecting my computer unless anyone tells me otherwise. Does anyone know of a virus that shuts downs virus checkers so that it cannot be found and therefore cannot be deleted? I haven't had any other problems with my computer apart from this, and I really need a full systems check done, which I can't do at the moment. Please help. Thanks in advance.
