I keep getting redirected to crawler.com?

Normally when I type something into the firefox address bar google takes over and finds it no problem. Since yesterday, when i installed spyware terminator and some silly wbecrawler toolbar (which i got ride of) it keeps redirecting me to www.crawler.com as a different search engine. even though i've removed this, and used loads of different spyware programs (adaware, spybot, malabytes) the problem remains. The programs can't find any problems, but something isn't right. What can i do?
