A file named "["?

[Beartooth]

	On one of my PCs, /bin contains an executable file whose name is 
the left square bracket, and nothing else. 

	Opening it with gedit gets something that's part text (generally 
if not all commented out) and part stuff I can't read.

	Is there a test, usable by one who knows no code, whether it's 
malware??

	What should I do?

I have precious (very precious!) little idea where up is.
