Resource shielding protects you against attempts to access vulnerable parts of your computer.

Resource shielding analyzes the behavior of all the programs already running on your computer and blocks any activity that looks as if it could be malicious. For example, it checks any changes being made to the Windows registry, which may indicate that malware is installing itself so that it starts automatically whenever you restart the computer.

Resource-shielding products usually allow you to set up your own rules about which resources should be protected.
