So for a few weeks my Norton is being messed up. I run Windows Vista and have had Norton AntiVirus 2009 ever since I got this laptop last year. Recently I noticed that Norton stopped doing stuff, so when I tried to open it, all that came up was a grey box. Any advice on how to fix it? I'm at a standstill :( Also, I have tried doing scans with Malwarebytes' Anti-Malware free scan too see if a virus had been doing this to my Norton, but nothing came up. I really need help.
