When you click on a web/html link in email Google Chrome or the default Internet Browser opens 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 is infected with a malware.
Download MalwareBytes and run it.
Then download and run AdwCleaner from the same site.
That should clean it up and remove it.
