W32/Fujacks-AK is an attempted virus and worm for the Windows platform.

W32/Fujacks-AK spreads to other network computers through available network shares and removable storage devices by coping itself with the filenames GameSetup.exe and setup.exe correspondingly.

It also creates the file autorun.inf to ensure that the file setup.exe is executed.
