What is tm.tradetracker.net and how do I remove it?

All of a sudden both my wifes and my own laptops (both with AVG on them) started to give us a threat remark: tm.tradetracker.net each time we login to out Google Chrome webbrowser. The id is: b111545a08c7/2024-02-01T18:14:34.002Z

I do not know what it is - and how to remove it. Please help.

 

Kind regards - Thobias
