Have you tried:

Clear your browser cache / surf history log

Run a scan with Malwarebytes Antimalware and Malwarebytes AdwCleaner

Hi E.RIC,

Very likely it is adware, see the flagged relations for that Google IP address here:
https://www.virustotal.com/gui/ip-address/74.125.124.157/relations  **

The address here is all green, but now kicks up a 404 error: https://www.virustotal.com/gui/url/9c613bcc7f97bd9e001f212a9dd80aba1e244b1a6ed5b58c97de72fadc69b526/details

Google's own VirusTotal is often the precise way to get an explanation for such problems,
a good run with MBAM & adwcleaner & a run with avast's CCleaner could do the job for you to cleanse it off of your machine.
** Securepubads & Admob issues.

Also consider the moved permanently twice here: https://www.shodan.io/host/74.125.124.157
Consider also critical errors here: https://zonemaster.iis.se/?resultid=2f174d25498914c8

Then attaching FRST diagnostic logs is next
