I just went to your website "paint.net" - it redirects to "Warren Paint & Color Co." - which appears to be a paint company in the US.

Did you perhaps mean getpaint.net? That's the download site for Paint.NET, a Windows-only paint program.

I did see an ad there at the top for "FileSendSuite" which does have a download button:

To me, it was reasonably clear the link was for FileSendSuite - but perhaps some other people could get mistaken?

If you hit the "x" in the top-right of any ad, you can report an ad (e.g. for being misleading/spammy), or simply say you never want to see that ad again (it gets filtered).
