Conficker Eye Chart

Here's a very simple way to see if your system has been infected with the Conficker Worm. Load this page and see if you can see all 6 logos at the top (be patient -- these sites are under a bit of load right now). Conficker blocks access to certain sites that can help you deal with it, and that's where these images are loaded from. If you can see the images, the Conficker isn't blocking your access, so you're not infected.
