Brief Description 

    

Fatso.A is a worm that ends processes belonging to several security tools, such as antivirus programs and firewalls, among others. This leaves the affected computer vulnerable to the attack of other malware.

This worm also prevents access to the websites of several antivirus companies.

Fatso.A spreads via the instant messaging program MSN Messenger and through peer-to-peer (P2P) file sharing programs. It also modifies the computer settings so that it is automatically copied to all the CD-ROMs that are burned on the affected computer.

Visible Symptoms 

    

Fatso.A is easy to recognize once it has affected the computer, as it opens Notepad and displays the following text when it is run:

Hey LARISSA fuck off, you fucking n00b!.. Bla bla to your fucking

Saving the world from Bropia, the world n33ds saving from you!
