About the Crash Defender agent

Most programs are made well and often work as they should. Even well made and brand name programs stop working unexpectedly. The Crash Defender agent protects your computer and data from the perils of unexpected system freezes. The Crash Defender agent is always running, monitoring your system and the programs you open. As the Crash Defender agent detects an imminent crash, known technically as a general protection fault (GPF), the Crash Defender agent notifies you of the problem and lets you fix it.
