When you click on a web/html link in email Google Chrome or the default Internet Browser open up the link plus two tabs. The two tabs would say…
“—use-spdy%3Doff’s server IP address could not be found”
“—disable-http2’s server IP address could not be found”
Your Windows PC might be infected with a malware.
Download MalwareBytes and run it. http://www.malwarebytes.com
Then download AdwCleaner from the same site.
That should clean it up and remove it for you.
