• dynamic link libraries (*.dll)
• HTML application (*.hta)
• Microsoft Office files (*.doc, *.ppt, *.xl?)
• Microsoft Works files (*.wps)
• Visual Basic files (*.vb?)
• screen saver files (*.scr)

traffic controlled by firewall policies.
To block files in firewall traffic

2 Add this content profile to firewall policies to apply content blocking to the traffic
