I am using Windows 10 which is patched through January. I use, for varying purposes, 4 browsers: Google Chrome; Edge; Opera; and Firefox. I use Malwarebytes and Acronis’s protection suite for malware. Computer is a Lenovo desktop which is about 6 years old. I use NordVPN as well.
Recently, I have found that all four browsers refuse to load webpages (so the problem does not seem to be related to a specific browser). There is no error message that I can find; I just get a blank page and the tab on the browser indicates it is trying to load the page.
I have tried various changes in my setup to see if that fixes the problem. I toggled the VPN on and off (because it is becoming increasingly clear that some websites refuse to load if you are using a VPN). I turned off Malwarebytes and the Acronis suite. I looked at Windows Defender, but it indicates that it is defaulting to the Acronis suite. I had a global privacy extension in a browser and deleted it.
I have another computer at the same location set up pretty much the same way which does not have any of these problems.
I am at a loss as to what additionally I can do to cure the problem.
