Brief Description 

    

Netsad.B is a worm that ends processes with a name containing certain text strings, if they are active. These processes belong to several security tools, such as antivirus programs and firewalls, among others, and ending them would leave the affected computer defenseless against the attack of other malware.

Netsad.B spreads via email and through the peer-to-peer (P2P) file sharing programs Emule, KaZaA, Gnucleus and Morpheus.

 

Note: in order to work properly, Netsad.B needs Microsoft .NET framework 2.0 to be installed on the affected computer.

Visible Symptoms 

    

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