How to Clear Scan & Shield Logs from SOA Console?

I am trying to figure out how to clear the Scan & Shield Logs from the SOA Console, I have searched with no success, is there a file I can just delete so it will regenerate a new file?

Nobody knows how to do this? Or does Avast just not allow it?

have you tried FAQ section http://www.avast.com/en-eu/faq.php

Yes, can’t find anything related to the clearing the logs in the SOA.
