If you’re worried about this <scary voice>virus of doom</scary voice> that everyone’s gone mental over, you might want to pop over to The Conficker Eye Chart that the Conficker Working Group has put together.
Basicially, the eye chart is a page that loads images from sites that Conficker actively blocks. So, if you can see all the images, you’re not infected. Pretty clever.
If you are infected, you might want to drop us a line.
