There is a simple way to test to see if your computer is infected with the conficker worm.
If you can visit http://www.symantec.com/ then your computer is not infected.
Conficker has blocked internet browsers from going to security sites such as Symantec, the maker of Norton security products.
Please keep your Windows operating system up to date, and keep your current anti-virus up to date and active to help protect you from this and other viruses.
