Hi there,
Well, there is a good guide by the howtogeek at http://www.howtogeek.com/198386/how-to-remove-trovi-conduit-search-protect-browser-hijack-malware/
It will help you remove search protect, and other possible spyware.
You may want to look at running Malwarebytes: https://www.malwarebytes.org/ with McAfee. They will not interfere, Malwarebytes is not an antivirus, its anti-malware (formerly known as spyware) which is different then viruses.
Good luck and let us know how it goes,
-Glen
