Conduit Malware?

I have been using Chrome for quite awhile, but this past month when I open the browser "Search Conduit.com comes up in the foreground and Ask.com is in the background. I can close out Conduit, and use Ask, but where is Chrome? Just today I've read on other threads about Conduit being Malware. I installed malwarebytes, ran a scan, deleted the bad file, but Conduit is still there. Is this malware and should I stop using Chrome. So fare Internet Explorer and Mozilla Firefox seem ok, but I'm looking for some professional advise. I looked at some thread on the forum, but did not understand what to do.

Thank you.
