I think, through my mediocre detective work, the Yahoo search engine is coming from Symantec

hxxps://search-yahoo-/yhs/search?typ...ion=244&cmpgn=catalyst&hspart=symantec&hsimp=yhs- <= dont click on the link I tried to disable it but the board is acting crazy

The reason I had asked if Nortons was working as it should is because I had seen a few errors reported through FRST
Date: 2019-05-15 14:01:03.837
Description:
Windows is unable to verify the image integrity of the file \Device\HarddiskVolume4\Program Files\Norton Security\Engine\22.17.1.50\WSCStub.exe because file hash could not be found on the system. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.

Through trying to go into help pages, others with the same issue, there actually was no resolve since they felt it was related to the security panel as being recognized as your antivirus, and it is....

OK
What we can do, remove the browser helpers from Nortons (If it will allow it), then reset the browsers back to default and see if this can stop whats been happening.
