Quarrentine message

I keep getting a message that a Threat has been secured.  It show up whenever I am using Chrome, and it appears several times whether I click X or choose scan my pc.  The Threat identified is always the same. 
      "We've safely aborted connection on go.domainxchange.xyz because it was infected with URL:Blacklist."   More threats may be lurking!  SCAN MY PC
How do I stop this repetitive notice?

For better clarity, share us the screenshot of the threat notification that you receive from AVG after clicking on 'See details' in it.
