You most likely have two different pages set as your home page. You can remove this second page from your list of home pages - see the instructions at How to set the home page

Do a malware check with a few malware scan programs. You need to use all programs because each detects different malware. - Malwarebytes' Anti-Malware - SuperAntispyware - Spybot Search & Destroy - Ad-Aware Free - Windows Defender: Home Page .......... See also "Spyware on Windows":

No I do not have two home pages. The page that pops up in the second browser is a health page, I would never set a page like this as a home page. An interesting thought though, thank you

Same annoying problem. This is some sort of pop-up ad. Probably need to clear cache and cookies. Will do Malware search.
