A weird executable has appeared in task manager startup,i tried running win defender and malwarebytes but nothing was found as a threat,the program's name is w32kg.exe and i just want to know if it is really a windows temp file or is it some virus,i managed to take ownership of it and it doesn't show anything new running in task manager except on startup where this program was enabled
there is the image of how it looks like
