I have an emachines computer with Norton Anti-virus protection.  My
computer keeps getting a message stating that I have been infected with a
virus and to click here to scan. I haven't click to scan because I was
told not to by norton, my computer manufacturer, and my internet
company. I have reinstalled with the discs several times. How can I prevent
tis from happening again. It's been twice in the past week. I would appreciate any help.
