I am starting out with composing music.

And a "friend" I have been talking with for a long time online wants to help me setup a template in my DAW/Cubase.

Can he while having control over my mouse send me a virus or steal anything from my computer without it showing up on the screen (the screen I see, with him controlling my mouse).
