Hi,

just a recent finding: When accessing e.g. a PDF document through a link, a new (empty) web page opens shortly, then the PDF is open. This is normal. But now, today (and I remember also in the last few days), this web page has some advertising for Windows 10 on it - which is not my home page, nor did I ever surfed there.

Maybe it helps?

Many thanks,
Lillebror. 8)
