Getting rid of a security threat

Hello, James

We will certainly look into this and help you.
Could you share the screenshot of AVG threat detection message?
You can post the screenshot here in your topic. Click on 'Answer' & then click on the 'Image' [mountain symbol] & follow the instructions.

About twenty times a day for the past week AVG has been reporting That is has aborted connection on wwsercher.biz because it was infected with URL:Blacklist. It then offers a button to SCAN MY PC, which I have done twice with no further threats found.
I am running Win 10 on a laptop HP Pavilion with a chrome browser.

How can I get rid of the problem and stop these notifications?
Please help.
I would post a screen shot, but there is no convenient way to do this.

Thank you, James.
Some unwanted extension or add on seems to be causing this.
Please reset Google chrome to default settings to resolve this issue.

I did the reset and so far (5 hours) it seems to have cured the problem.
Thanks for your help.

I am glad that you issue has been resolved, James
I appreciate your time and effort in this.
