Blocked Files

Defense+ allows you to lock-down files and folders by completely denying all access rights to them from other processes or users - effectively cutting it off from the rest of your system. If the file you block is an executable, then neither you nor anything else is able to run that program. Unlike files that are placed in 'Protected Files', users cannot selectively allow any process access to a blocked file.

Clicking the handle at the bottom of the interface opens an options panel with the following options:

• Add – Allows you to add individual files, programs, applications to Blocked Files.

• Edit – Allows you to edit the path of the file.

• Remove - Releases the currently highlighted file from the blocked files list.

• Delete - Deletes the highlighted file from your computer.

• Purge - Runs a system check to verify that all the files listed are actually installed on the host machine at the path specified. If not, the file or the file group is removed, or 'purged', from the list.

To manually add an individual file or application

• Click the handle from the bottom center and select 'Add'.

 To edit an item in the Blocked Files list

• Select the item from the list, click the handle from the bottom and select Edit. The 'Edit Property' dialog will appear.

• Edit the file path, if you have relocated the file and click OK

To release an item from Blocked Files list

• Select the item from the list, click the handle from the bottom and select 'Remove'.

The selected item will be removed from the Blocked Files list. CIS will not block the application or file from execution or opening then onwards.

To permanently delete a blocked file from your system

• Select the item from the list, click the up arrow from the bottom and select 'Delete'.

The selected item will be deleted from your computer immediately.
