Virus? Please help me keyboard / mouse?

Hi. For about 3 days now it has been around 6 p.m. At a random time. Simply press buttons / combinations. The whole thing seems randomized, but if I don't counter it by permanently tapping into Minecraft, the PowerShell opens very quickly.

If you have a virus, you should stay at home and call your family doctor. Get well.

Then you should

update your windows
do a full review with the Defender
let the friend run over here -> https://de.malwarebytes.com/...dwcleaner/

let us know what has been found and whether your problem is solved:-)

Many thanks too
