Conficker Eye Chart
Conficker, also known as Downadup or Kido has been one of the most widespread worms recently. There are numerous symptoms, and if you’re not a PC expert it can be hard to interpret those symptoms and be sure what has happened. Fortunately there is a fast, easy test that can help determine if you have a Conficker infection, cleverly known as the Conficker Eye Chart. Just a quick look and comparison with the explanation on the page and you’ve got a good idea whether or not Conficker may have infected your PC.
|Conficker (aka Downadup, Kido) is known to block access to over 100 anti-virus and security websites. |
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.
