Brief Description 

    

Mitglieder.AY is a worm that ends processes belonging to applications that provide updates for different antivirus programs.

Every six hours, Mitglieder.AY attempts to download a file from different web addresses. If successful, this file downloads and runs other malware on the affected computer.

Mitglieder.AY scans for IP addresses in which the TCP port 81 is opened, which the worms Bagle.BC and Bagle.BE listen to when they affect a computer. It makes a copy of itself to those computers, without user intervention.

Visible Symptoms 

    

Mitglieder.AY is difficult to recognize, as it does not display any messages or warnings that indicate it has reached the computer.
