How to Uninstall Savebigonsearch.info Browser Hijacker Virus As Homepage

When I open howtouninstallvirus.com up Mozilla Firefox, the site called Savebigonsearch.info pops up as opposed to Google. I downloaded one thing on accident yesterday, and also I think I have gotten the herpes virus through it. I went to Uninstall applications on my pc as well as I cant seem to locate exactly where this 1 is coming from. How do I uninstall this?
