I was notified by a pop up from logMeIn that I had a Trojan virus and hackers attempting to get through. I could clear it all up for $350 that I needed to load on a I tunes card at CVs... Cvs informed me that this could possibly be a scam, so I didn't purchase it. Is there a legite way to see if I really do have a virus. My computer has been working well now, but before I left for cvs there were windows I couldn't close at all... And a flashing that stated I had a virus...
