I installed Faronics Anti-Executable Standard v2.20.00.0255 today in my frozen on-line snapshot. http://www.faronics.com/html/AntiExec.asp I've put it on HIGH Security Settings and it 1. Blocks unauthorized 16-bit executables 2. Blocks unauthorized 32-bit executables 3. Protects Anti-Executable Standard directory from access and tampering 4. Blocks unauthorized drivers and .dll files 5. Network Prevention is enabled I couldn't enable "Delete Prevention" yet. I couldn't enable "Copy Prevention" yet. I still have to figure out how to enable these. It's a well hidden software : 1. It doesn't appear in the "Add or Remove Programs", so you can't uninstall it. 2. It doesn't appear in the menu of "All Programs" 3. The icon is visible, but can be hidden and doesn't react on click or right click. 4. You can see a folder under "Program Files", but you can't access it. 5. You need a password to change the configuration or to turn it OFF. Quite an unusual software. I hope its protection is also unusual strong. Time will prove. This software is an evergreen of course and will be always usefull, because it doesn't require signature updatings.
