In that case, go to Safari>Preferences>Websites and look to see if you have any plug-ins installed. Disable them (along with your extensions—all of them), change your homepage to a site that you trust like Apple or Google (go to Safari>Preferences>General and edit that little box), quit Safari, restart your computer, and then re-open Safari. Let me know if that works!

Also go to Safari>Preferences>Extensions and make sure that you don't have a Wow.com extension enabled in there...

Force Quit Safari ( command + option + esc keys).Then restart Safari holding the Shift key. If you still have problems Empty Caches (Safari menu > Preferences > Privacy > Remove all website data. (This will also remove history if you do not want to remove History open Safari Preferences > Advanced and check mark “Show Develop Menu” then choose “Empty Caches” from Develop Menu ) If the problem persists download and run MalwareBytes.
