Please help me remove my adware! (Spigot)

Hello guys!

I just bought an macbook pro and installed a program, which I unfortunately didn't know was bundled with an adware(Spigot?).

As I want my macbook as clean as possible and the fact that I am virus paranoid I changed back my safari start page, deleted the safari extension and deleted the Spigot users/*myname*/library.../spigot directory.

Did I remove EVERYTHING bundled with this adware? Are there any registry files left to remove or something?

Thank you for reading (and hopefully helping me out)!
