Select “Verification status” and “Verified signer”, and add both to the active columns list.


To view only non-signed processes, use the menu option View –> Hide signed processes.


An error dialog box may appear:


Under Options –> Advanced, enable the selection for “Check images for digital signatures and packing”.  A restart of the application will probably be required.


A process entry can be submitted to VirusTotal by using the right-click –> Send to –> option.
