I just did a clean install of Windows 10 x64 on my PC. I still would have Firefox, Chrome, and MS Edge Browsers crash or not connect to the Internet, thought the PC could see the internet. I had spent hours and days trouble shooting and researching on the internet for a fix. When the clean install did not fix the problem I had begun to think there must be no solution to this problem at the present time. I found out that Malware Bytes process once closed on my PC was the culprit. I am running Sophos UTM Antivirus as my primary virus protection on the PC. This never had caused any issues, it was not until Malware Bytes was installed that the issue started. My PC does have the Anniversary Update installed on it, and I am using the Spy Bot Anti-Beacon, which works well for stopping some of bloatware and spyware MS has bundled with Windows 10. All my browsers now work like normal, and open without crashing. Hopefully if anyone else experiences this same problem comes across this little blurb.
