A few days ago, after years of no problems, Edge suddenly has a policy setting Bing as the default search engine for the address bar. I have always configured Edge to use Google as the search engine.
This is not a system belonging to a company or organization; it is my private PC.
I scanned for malware with my Vipre and with Malwarebytes; nothing found.
I reset the Edge settings to default, no change.
I deleted the policy from Registry, and the policy was gone.
However, after an hour or so, suddenly reinstates the policy. I can be looking at the Edge://policy page, and it magically changes from no policy to enabling that policy.
I delete the registry data again and it is good for another hour or so, then it is back.
I had installed a couple of programs recently, maybe about the same time this problem started. I uninstalled both programs, including searching and deleting from the Registry all references to those programs.
Scanned for malware again, nothing found.
Nothing changed regarding the persistent policy.
