An easy way to check for the conficker worm

If you are blocked from loading the remote images in the first row of the top table above (AV/security sites) but not blocked from loading the remote images in the second row (websites of alternative operating systems) then your Windows PC may be infected by Conficker (or some other malicious software).

If you can see all six images in both rows of the top table, you are either not infected by Conficker, or you may be using a proxy server, in which case you will not be able to use this test to make an accurate determination, since Conficker will be unable to block you from viewing the AV/security sites.

Joe Stewart from SecureWorks has put together this effective "eye chart" that sources its graphics from sites that Conficker would block. If you can't see one or more of the images, you're either infected, or image loading in your browser has been disabled.
