You can configure PortalProtect to block files according to the file type and file name and select the action for all the files that match your configuration. When you enable file blocking, PortalProtect blocks the files according to your configurations. File blocking can occur during real-time, manual, and scheduled scanning according to the settings you choose.

The extension of a file identifies the file type, for example .txt, .exe, or .dll. Many viruses are closely associated with certain types of files. Some virus writers have tried to disguise their files by using extension names that are known to be harmless, so true file type blocking scans the header of files to determine their actual type. By configuring PortalProtect to block according to file type, you can decrease the security risk to your SharePoint servers from those types of files. Similarly, specific attacks are often associated with a specific file name. If you learn the name of an infected file, you can use PortalProtect to screen that file out of your SharePoint. Blocking is an effective way to control virus outbreaks.
