My computer has been infected with a virus that won't let me get on the internet even though I have an active internet connection, Norton won't detect it and the virus is preventing spyware doctor from working! I downloaded another virus eliminator onto my USB flash drive but when I insert it into my computer, the flash drive doesn't show up even when I look for it in my computer! How do I get rid of this virus?My USB flash drive works fine on other comps. Again I have NO internet connection on that comp. Im thinking that it might be a....rootkit virus but Im not sure.
