Thanks for all the help.  I have at least surpressed the problem but there seems to be some dispute as if this is a virus or not.  Certainly a couple of the anti-virus programs cannot see it.  In the end I have used the Adblock extension in Chrome.

foxylady is right though in that it does not come from the site and is PC dependant it is just that Rendo is the site I use the most.  I am sure it would have appeared on others if I had not surpressed it.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
