Chance

I wonder whether some game could do such thing. I had my session running for a while, and in between my son used the computer with his own account. He watched youtube, played browser-games and Roblox.

Thank you itman, I disbaled RDP in both Win10 and Eset.

I am running Win 10 Pro, and way back when the computer was new (maybe 3 years ago) I did try RDP but have never seriously used it and certainly not within the last year. I do however use TeamViewer (support for my mother and my father-in-law) and RealVNC on a regular basis.

(1) My immediate concern is gone. After a reboot, the secure browser behaves as usual. (2) I am still curious what may have happened, so I have attached the screenshot, in case you are still willing to have a look at it. The text in the little grey box is the same as the text in the yellow box. Thank you so much!

Thank you for this quick answer. No, I am not connected by RDP, I am working directly at the machine (with keyboard, mouse, LAN and monitor attached).

I have been using Eset Internet Security for a couple of years, but this message was new to me: When I opened the secure browser, I got a warning message like this: "This computer is remotely controlled. Using internet banking may be unsafe. In case you use this software by pupose, you can safely ignore this message. The remote access software is: svchost.exe" (translated by myself, so the original wording will likely be quite different.) I am not aware of my machine being remotely controlled, but I have seen svchost.exe running in the past as well. So I wonder what to make from this message - is there a threat to me? How to find out?
