Enterprise Vault 64-bit Index broker uses Windows and inetpub temporary folder for search queries and results. Many organizations feel that these folders present a security risk, and will not exclude them from Anti-Virus (AV) scans. As a result, McAfee has been known to falsely identify EV index related items as a threat, and block access to these items.
Ensure that the correct antivirus folder-level exclusions recommended for Enterprise Vault are in place. See 100017720
Ensure that the following antivirus folder-level exclusions are excluded from antivirus scanning on the Enterprise Vault servers:
- **\Windows\inf\Enterprise Vault Index Query Server\
- <install_path>Program Files (x86)\Enterprise Vault\EVIndexing\data
- <install_path>\Users\<VaultServiceAccount>\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.IE5
If Access Protection is enabled, monitor the Access Protection logs for blocked Enterprise Vault processes, and exclude those processes from the Access Protection Rules.
After extensive testing, it has been determined that even with all of these exclusions in place, EV cannot be reliably configured to work properly with McAfee 8.8 Patch 4. Further testing determined that Patch 5 and Patch 6 did not experience the same issues. As a result, McAfee 8.8 Patch 4 is no longer supported. Please see the compatibility guide, in the related articles section, for supported versions.
McAfee Antivirus 8.8.
