'Cannot connect due to proxy settings'.. that keep changing back auto

Hello, i've looked around and am unsure how to solve this or what direction to further go in.. at least daily, and the time it happens is random, my browsers will not connect to the internet and it tells me it cannot connect because of proxy settings.. in the image below circled in red are the two settings I have to constantly go back and change in order to access the internet.. it just keeps changing them back for some reason. Last month it only happened on the Edge browser, not on Firefox.. but since I did a reset of the OS, now it happens on both browsers.

It's normally either your security software doing it so it can scan everything or you have malware or virus it's running on your local PC what anti virus have you got?

I just have the basic Windows Defender built into Windows 10.. plus from time to time CCleaner and Malwarebytes..
nothing malicious found with any of these..

Please download and save FRST 64bit or FRST 32 bit to your Desktop.

Right click to run as administrator (XP users click run after receipt of Windows Security Warning - Open File). When the tool opens click Yes to disclaimer.
Make sure that Addition option is checked.
Press Scan button.
It will produce a log called FRST.txt in the same directory the tool is run from.
Please copy and paste log back here.
The first time the tool is run it generates another log (Addition.txt - also located in the same directory as FRST.exe/FRST64.exe). Please also paste that along with the FRST.txt into your reply.

I have the same problem and Internet Explorer and Edge can't connect to proxy server. ANy further help to resolve this is appreciated.
