Removing toolbars. How to do it?

[Buffy The Cache Coder]

I must have gone to some offending site that installed
in my internet explorer's browser window another toolbar.

Much like when I got on one day, and the yahoo site
intalled theirs. However, I don't mind Yahoo's.

I do mind the new one. How do I remove it? Right clicking it
doesn't seem to work. Also, I want it totally removed,
not just cosmetically hidden. So that is, wherever this
thing is hiding in my harddrive, I'd like to remove it.

I'm rather clueless, so some step by step instructions would
really help. Thanks!
