If you suddenly start seeing messages on your computer that you have various viruses and you need to buy something to get rid of them, don’t do it. Your computer has probably been infected with the Internet Security 2010 malware, which is a program that gets downloaded to your computer when you visit an unsafe site. How do you know if a site is unsafe?
I use Norton Internet Security and it has a “Norton Safe Search” feature that I can use and it will put a little green icon by sites that Norton found safe when it visited them.
But if it’s too late or you’re curious about this “virus/trojan/rogue program”, then visit this blog by a Symantec employee for more information and instructions on removing the fake program.
