How can you detect if your computer has been violated and infected with DNS Changer?

An industry wide team has developed easy “are you infected” web sites. They are a quick way to determine if you are infected with DNS Changer. Each site is designed for any normal computer user to browse to a link, follow the instructions, and see if they might be infected. Each site has instructions in their local languages on the next steps to clean up possible infections.


For example, the http://www.dns-ok.us/ will state if you are or are not infected (see below).
No Software is Downloaded! The tools do not need to to load any software on your computer to perform the check.
No changes are performed on your computer! Nothing is changed on your computer when you use sites like http://www.dns-ok.us/.
No scanning! The “are you infected with DNS Changer” tool does not need to scan your computer.

If you think your computer is infected with DNS Changer or any other malware, please refer to the security guides from your operating system or the self -help references from our fix page (http://www.dcwg.org/fix).

The following table is a list of all easy “are you infected” sites. It includes the links to the security organizations who are maintaining the sites. Each site has instructions in their local languages on the next steps to clean up possible infections.

If you are not affected by DNS Changer then do nothing.
