Looks like it is back to the Adobe Settings Manager. I'll make my suggestions below, but you may need to tweak them to suit your needs. Each setting is described below the settings manager box.
Global Privacy Settings panel -- Always deny
Global Storage Settings panel -- Slider to the left, Always deny,
Global Security Settings panel -- Always ask (this is where you gave permission to kerkida.net)
Global Notifications Settings panel -- Keep the notify box checked, although you can change the date to 14 days.
Website Privacy Settings panel -- Always deny + click "Delete all sites"
Website Storage Settings panel -- This is likely the one you need to experiment with. I use None, Never ask again, and all sites deleted.
Protected Content Playback Settings panel -- Leave as is
Peer-Assisted Networking Panel -- Always deny, Disable P2P uplink, Delete all sites
If you have no luck with the settings changes, you may need to uninstall Adobe Flash Player and re-install it again. The uninstaller is here: http://download.macromedia.com/get/flashplayer/current/support/uninstall_flash_player.exe
