Search engine problems for a computer illeterate

[Anhaga]

I originally posted this in the OT forum:

"I installed the google toolbar a few months ago. Shortly after I did this, I was unable to access google or any search engine besides MSN. This problem still persists. I can get on to Yahoo but if I try to search it just says that the page cannot be found.
If I type in www.google.com, I get a message saying that "There is no website configured at this address".
Any ideas?"

Among the responses were these:

Sounds like K-meleon installed a hijacker. Mosey along to G&C.

How the fuck could K-Meleon install a hijacker? It's fucking built on Mozilla, for fuck's sake. The only thing it has in common with IE is a user interface.

IE is more than likely the culprit. Mosey on over to G&C anyway.

So I've moseyed and I plead for help. I've been google-less for over two months now.
