What is block.opendns.com?
When I attempt to visit certain websites, like support.apple.com, I get redirected to block.opendns.com, with a warning message, and a strange picture of a man. Is this malware?
MacBook Air, macOS High Sierra (10.13.5)

Malwarebytes did the trick for me. Thank you!
OpenDNS is a site that offers a free DNS server and data encryption services. I suppose block.opendns.com is for some anti-malware software or Safari extension that tries to block OpenDNS from running or invokes OpenDNS to block the site you are trying to access. This isn't an Apple product nor part of macOS. It's third-party software you installed.
When I attempt to log in to apple.com I get a dialog box reading: This Connection Is Not Private. This website may be impersonating “www.apple.com” to steal your personal or financial information. You should go back to the previous page.
Now the behavior seems different.
And when I browse to support.apple.com I get: Safari can’t open the page because Safari can’t establish a secure connection to the server “support.apple.com”.
