How to remove infection:URL:Blacklist under www.Google-analytics.com

Since August 8, I am getting the following pop-up warning message:
“Threat Secured–We have safely aborted connection on www.Google-analytics.com because it was infected with URL:Blacklist-Scan my PC”

Even after scanning my PC and getting OK sign, the above error message is continue to come.

Can any body advise me the solution:

Can you post a result from nslookup on www.google-analytics.com ? It might be a DNS hijack case.

Also, I’d suggest running a Wifi-inspector scan. You should get more info from it.
