web shield detection of r.linksprf.com

Since end of 2023 I can see detection/blocking of web r.linksprf.com with diffrent kinds of path. Avast antivirus team confirmed that this Hostname/those URLs are correctly detected.
I was not able until now to figure out where this is comming from.

Fact is that detections in such an amount is usually a false positive. In the past this has almost always confirmed from the antivirus team of Avast. This one is diffrent…

Any idea what this is all about? I assume that other partners will also have an incresed detection of this host name?!?
