Creating Mutual Exclusion Handling on Malware Processes/Files

Views:

You can configure Outbreak Prevention to protect against security threats that utilize mutex processes by overriding the resources that the threat requires to infect and spread throughout the system. Outbreak Prevention creates mutual exclusions on files and processes related to known malware, preventing the malware from accessing these resources.

Tip:

Trend Micro recommends maintaining these exclusions until a solution to the malware threat can be implemented. Contact Support to obtain the correct mutex names to protect against during an outbreak.

Note:

Mutual exclusion handling requires the Unauthorized Change Prevention Service and only supports 32-bit platforms.

Go to Agents > Outbreak Prevention.
In the agent tree, click the root domain icon () to include all agents or select specific domains or agents.
Click Start Outbreak Prevention.
Click Create mutual exclusion (mutex) handling on malware processes/files.
