Hello,

Same problem here, i've got this issue in version 3.08, and it is still here in 3.10 build 2364.
I've followed your instructions too :
  • Setup a share for virus quarantine
  • Selected switch.clamav.net as the update mirror
  • Selected "Update interval" : Now and every 1 hour
  • SMB protocol scanning activated

It updates perfectly when i manually click on "Apply" button, but it fails to update automatically...

Thanks for your help.
