Brief Description 

    

MTX.Troj is a worm that reaches computers in a file attached to an e-mail with a PIF, EXE or SCR extension.

Its strategy for avoiding detection is passing itself off as a harmless music file or photograph, which will have a variable name and will generally be related to a famous person like Bill Gates, Jimi Hendrix, Metallica, etc.

MTX.Troj spread automatically and very rapidly by sending itself to all the contacts in the Address Book, except those that correspond to antivirus companies. It main effect is that it infects executable files.
