Free Anti-Spyware Program?

I had an anti-spyware program on my old computer, but I cant remember the name. It had a small orange head with sunglasses and a detective hat and coat. It worked really well and it was free for download off the internet, but I cant remember what it was called. If anyone can tell me what it is called, please tell.

Malware bytes and Hijack this. These two are by far the best free programs. Good luck!
