Too little info.

Variant 1: You come to the touchpad under the keyboard (in particular with notebooks), mark a part of the text and as soon as you press any character or backspace/Entf/Enter/Return, the marked is away.

Variant 2: You’ve installed evil shit that’s trying to upset you. Either malicious software or a superfluous software from the keyboard manufacturer. Move it. Especially with proper malicious software, you have to find out what you have and how it goes away or better install properly fresh (do not refresh/install!).

Version 3: Your keyboard is crap and needs more power -> use other USB sockets directly on the computer, best USB>=3.0.
