Problem Description

Antivirus scanning can degrade the performance of Forcepoint components. This article lists folders and files that should be excluded from antivirus scans.

Please note:
  • Forcepoint is not aware of a risk in excluding the files or folders that are mentioned in this section from your antivirus scans. However, it is possible that your system would be safer if you did not exclude them.
  • When you scan these files, performance and operating system reliability problems may occur because of file locking.
  • Do not exclude any files based on the filename extension. For example, do not exclude all files that have a .dit extension.

Refer to your antivirus vendor's documentation for instructions on excluding files from scans.

NOTE: During installation of Forcepoint products, disable antivirus software altogether. After installation, re-enable antivirus software.


NOTE: The DLP Endpoint has been renamed several times:

  • TRITON AP-ENDPOINT DLP was renamed Forcepoint DLP Endpoint in v8.4.x.
  • Forcepoint DLP Endpoint was renamed Forcepoint One Endpoint (DLP) in v18.12.x (released with DLP v8.6 and Web Security v8.5.3)
  • Forcepoint DLP Endpoint is again used in v19.03 and higher.

This KBA refers to all DLP Endpoints by its current name: Forcepoint DLP Endpoint
