Application Protection
Introduction BlackICE protects your computer from unknown applications and from applications
connecting to a network, such as the Internet.
How the baseline
works
First, BlackICE creates a baseline record (also known as a checksum) of the applications
installed on your computer. Then it compares that baseline with any application that
attempts to launch or to communicate with a network. If the application does not match
the baseline, then BlackICE asks you if you want to stop the application or let it continue.
Note: You must update the baseline whenever you make changes to your system, such as
upgrading an application or installing a new application.
Turning off
Application
Protection
To turn off the Application Protection component:
1. Click Tools
ÆEdit BlackICE Settings.
2. Select either the Application Control tab or the Communications Control tab.
3. Clear the Enable Application Protection check box.
Adding new or
upgraded
applications to your
computer
Whenever you upgrade an application or install a new application on your computer, the
application does not match the Application Protection baseline, so BlackICE regards it as
an unknown application. This protects you from someone maliciously updating
applications with or replacing them with other files that may be harmful.
Avoiding alert
messages when you
install software
You can avoid warning messages during upgrade or installation by clicking Install Mode
Options
Æ Enable Install Mode on the first message you see. This temporarily disables
Application Protection. Click Continue on the periodic messages until the upgrade or
installation ends. Be sure to disable install mode when you are finished.
Note: After you install or upgrade an application, you must add it to the baseline. For
information about updating your baseline to include your new or upgraded software, see
Managing your authorized applications on page 44.
