I have installed Wise Disk Cleaner (portable) but the file "autostart.exe" was blocked by Bitdefender Internet Security ( advanced threat defense ) as " Gensuspicious.cloud.4.pqw@auva30gi ".
Ah okay didn't knew that. I thought about this becuase on the screenshot is the detection in the %temp% folder. It was just definetly unpacked because it is portable. So sorry for blaming you @Omarzwai ! But a second opinion scan would be very interresting!
