  • IMPROVED! Self-Defense:
    - There has been various reports that CFP 3.0 is attacked by some malware to disable its protection.
    The self defense has been modified such that an ungraceful termination of CFP will block every unknown action (i.e. it will function as if "Block all unknown actions if the application is closed" option is selected. This option was not enabled by default).
  • IMPROVED! Default Configuration:
    - Default configuration now protects more registry keys and more COM interfaces.
    - Default Web Browser and FTP Client policies are modified to support passive FTP requests
  • IMPROVED! Handling of known code executing applications:
    - Defense+ has been modified such that some known code executing programs such as rundll32.exe or windows scripting host are not automatically trusted anymore.
  • IMPROVED! Pending Files:
    - Defense+ has been modified such that it is not going to report any pending files if it is not in clean PC mode.
  • FIXED! Bugs in Defense+ Engine:
    - Fixed numerous bugs that could stop Defense+ to properly handle the suspicious actions(e.g.bugs in registry and file protection, key logging etc).
    - Fixed the bug that could prevent CFP from functioning properly in certain types of hardware configurations(e.g. when a USB harddisk is present etc.).
  • FIXED! Minor Bugs in the Graphical User Interface


  • Fixed the bug causing Windows Updates to fail in Windows Vista
  • Fixed the bug causing Windows to show "Access Denied" message while deleting a folder


  • VPN Clients can now connect to VPN servers
  • cmdagent.exe no longer consumes 100% CPU
  • System reboot no longer takes too long when CFP is installed with some other security software, e.g. avast!
  • CFP can now find the application behind a connection (for example Kaspersky web scanner)
  • "System Idle Process" is now changed to "Windows Operating System" to describe application less traffic (So no more "System Idle Process" in CFP)
  • Internet Connection Sharing (ICS): CFP is now compatible with ICS servers (users will be required to answer some popup alerts)
  • System performance has been improved
  • Defense+ no longer allows some applications to modify a protected file if it is not allowed
  • Eliminated 8.3 path conversion and its associated duplicate entries/not remembering my answer problems (e.g. for BOClean or AVG)
  • If CFP.exe is active, trying to rerun cfp.exe will activate the currently active CFP.exe instance now
  • Accidental BLOCK/ALLOW for image execution popups are NOT remembered through out the application life time anymore (This means if an application is blocked/allowed from being executed without remembering, it will be asked again).
  • Default global rules for NON-P2P mode has now been changed to allow various incoming ICMP messages that affects windows updates and trace routing applications
  • New application signature database has been introduced; the size and format has been significantly changed to prevent false alerts from some AV programs
  • Crashes while opening help file from the GUI links have been eliminated
  • Crashes related to password protection dialog have also been eliminated
  • Introduced the defense against a new keylogging technique
