what is uspy?

I was going thru my folders cleaning out un-needed files when I found a uspy folder in my home library/applicaiton support...it included uspy.ini, uspy.save, and uspy.log. .... can anyone tell me what this is for? i googled it and found stuff about uspy.exe for windows and something about it being associated w/ a cam which i do have...just want to know if it's something i should be worried about because i've recently been having a problem w/ disk space disappearing
