Weird program in $PATH

[Heiko Becker <heikobecker92@xxxxxxxxx>]

Hey everyone,

today I tried to launch firefox from my awesome-wm launcher and instead 
of being offered firefox after typing fire, the prompt finished showing 
me alternatives and being a little lazy I just pushed enter. This gave 
me a window with some fire particle animations running on my screen.

Searching for the program in my pacman.log did not show me anything so 
I'm wondering where this program comes from. Can anyone of you maybe 
help me to at least get this thing removed without having any files left 
that are only used by this program?

Best regards,

Heiko
