Summary

Invisible is a polymorphic multipartite virus which infectes COM and EXE files and Master Boot sectors on hard drives. The virus is polymorphic in the MBR infections as well.

Sometimes the Invisible virus will overwrite COM or EXE files with a short trojan which will play the tune of the 'Invisible Man' song by Queen and display it's lyrics on the screen:

        I'm the invisible man,
        I'm the invisible man,
        Incredible how you can
        See right through me.

        I'm the invisible man,
        I'm the invisible man,
        It's criminal how I can
        See right through you.

The virus also contains the following text:

        The Invisible Man - Written in SALERNO (ITALY), October
        1992.Dedicated to Ester: I don't know either how or when,
        but I will hold you in my arms again.
