I recently picked up a virus. My NAV it appears to have affected NAV. I cannot turn it on. I have a security error popup that tells me it is not on. When I open it and go to the process of turning it on nothing happens. There is an error in email that indicates there was a virus. I know I picked up the Alcan worm or something. Can anyone help....I am so fraustrated and have no idea where to begin.
