Helps heaps, thanks so far! BUT, I still have a process running which is not assigned to a python script anymore (I deleted it). The one that was associated to a python script I could terminate with the script in the link you sent, but the one that's been there even before that, I somehow can't terminate. Tried with os.kill and the according PID but it did nothing. Any hints regarding that, maybe? EDIT: It somehow just worked now. I could kill all relevant processes. Thanks @Bailey and by extension @Krydos!
