A virus (worm.win32.NetSky) got past my Norton 360 Anti-Virus program and infected my computer. Simultaneously, ads from a company called,Internet Security 2010 began appearing on-screen, promising to remove the virus if I paid them .95. I suspect that this company infected my computer so that they can be paid to remove it. I have reported this to the FCC and they are investigating. In the meantime, many of my computer functions have been disabled. Can anyone out there help me?
