I set Google as my default search engine. However, when I open Firefox, I see a box that says "Potential Threat Detected". The page is headed with a wifi symbol inside a blue shield and below that is says "Hold On!" We blocked access to http://www.searchbaron.com/v1/hp?aid=26025. This site might compromise your device or contain dangerous content. To avoid these risks, close this window and skip this site. Proceed anyway. The same message is duplicated in 3 other languages. So I open a new tab and close this one and everything works fine. Can anyone tell me what to do to stop getting this? I'm not computer savvy so please be specific. I'm not close to an Apple Store, but can get to one if I have to.
