Register keys of Firefox

Hi all ,

I have a question.
I removed Firefox from my system , it was a rather old version of FireFox. Since I didn’t use Firefox , I uninstalled it.

I installed SpywareBlaster and SpywareGuard.
SpywareBlaster tells me that I still have Firefox , how do I get rid of those register keys of FireFox ?

Thank you.

Greetings ,
