The file: gkmixern.sys was one morning on my pc in the "C:\Doc and Settings\[userrname]\Local Settings\Temp"-folder. I can not scan it with Norton,Trojanremover,and others . They all say it is in use.I can't delete it or change its name. I looked at the web with Google +Copernic+Ixquick, but didn't find anythying ! I even looked in Microsoft Knowledge base etc. ,but...Nothing! Please does anyone know what it is?
