Windows is not among the safest desktop operating systems available. Security experts advise using antivirus tools on Windows operating systems. The good news is that several security tools, such as Antivirus, Anti-Malware, firewalls, VPNs, etc., are accessible on the Internet to defend Windows from security threats. Unfortunately, Windows users still see warning messages despite all of these tools, particularly in their online browsers. Error ‘ERR_CERT_AUTHORITY_INVALID’ is one of Chrome’s most common web browser errors. The error message is accompanied by the text “Your Connection is not private.” If you see the same error message when you visit your favorite website, it does not necessarily indicate that the site you are going to visit is dangerous. The ‘ERR CERT AUTHORITY INVALID’ error happens when the issued certificate is no longer valid; the browser is no longer supported, etc.
