is also known as Downadup
W32.Downadup.B is a worm that infects computers by exploiting the Microsoft Windows Server Service RPC Handling Remote Code Execution Vulnerability. This virus was detected in December 2008 and since then it is spreading all over the world. Various sources have said that somewhere between 3million and 10million systems have been infected already.
W32.Downadup.B monitors DNS requests to certain domains and blocks access to them causing network request timed out notification to show up. Typically, users gets a Windows alert saying that there is no network provider. However users still can ping the computer name or IP Address. W32.Downadup.B also creates autorun.inf file on all mapped drives and automatically executes it when the drive is accessed. Then the virus monitors for other computers that are connected to the infected computer. W32.Downadup.B creates autorun.inf as soon as other computer becomes accessible.
Most of the anti-spywares are worthless against this virus. Manual removal instructions will not work too, because registry permissions have to be restored, before registry keys are removed. The most effective way to avoid W32.Downadup.B is to use the registry to block Autorun of external media and to use a strong administrator password.
