How Can I Clean up XeeSearch.com popup on browsers completely?

Every time I try to load a page, I get redirected to a search provider called Xee Search. It seems there are some problems on my Firefox and it just keeps sending me to XeeSearch.com again and again. That is really annoying. I am not sure if it is a virus. I have tried clearing the cache, also tried to uninstall and reinstall my browser, yet the problem isn’t resolved. Also I’ve tried running Malware bytes, a few times, now it’s telling me it’s “clean” and tried Hitman Pro, saying it’s “clean” too. I am NOT tech savvy, any help to get rid of this hijacker threat will be appreciated.
