Startet mit Windows, was den Start Process verlangsamt wenn Kaspersky mit läuft.
Being an AMD driver application it should not be of any security concern.
i just know it wasnt here, i keep an eye on Taskmanager. So i think it is safe and logical to just "kill" it.
It´s an AMD-Video-Card driver and it´s necessarily important for an correctly running system.
