While the article is written with VirusScan in mind, the third party AV should have similar exclusion settings.
From the article:
Exclude Host DLP processes
The processes to exclude for Host DLP are as follows:
- fcagt.exe (Host DLP 2.2 and earlier)
- C:\Program Files\McAfee\DLP\Agent
- C:\Program Files\McAfee\DLP\Agent\Vista32
Thanks Tony. With these exceptions, the performance is better and DLP is working fine.
