Brief Description 

    

Atak.B is a worm that spreads via e-mail in a message with variable characteristics, and through peer-to-peer (P2P) file sharing programs.

Atak.B checks if certain processes are active in memory, and if so, it ends them. Such processes belong both to other worms, adware, spyware, etc. and to antivirus programs and firewalls, among other security tools. Ending these security processes leaves the affected computer vulnerable to the attack of other malware.

Atak.B also checks if there is an active debugger in the affected computer, and if so, it stops this program.

Visible Symptoms 

    

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