[Stdrt.exe playing random music!]

Hello!

I have had this virus/malware on my computer for a while now. When i start up my windows there is always a file called "stdrt.exe" running and it takes up alot of memory. It will also play random music, like from commercials.. Please help me to remove this virus, i have tried to scan my computer with Malwarebytes but it wont find the virus it seems.

I am not that in to this kind of stuff so "beginner" instructions would be very appreciated!
