A virus that kills Linux off. It comes as a videogame called "Star Shooters", but requires installation to be done under "root" account to set up 3D stuff. When the unsuspecting Linux user logs on as "root" to have fun with the game, it will quickly go and erase all password files, all of the files in the /bin folder, wull shut off Apache for good, and will screw up desktop settings. Additionaly, it will create random HUGE files in random locations of the disk to eat hard disk space. And then the Linux user will say: "Holy shit, they screwed me, just like any normal Windows user." Pwn3d.
This is actually a warning to let you know that, you are not safe, not even on Linux. The most trivial software may one day wipe your ass.
