I would advise that you test and apply the latest Patches for the products that you are using.
McAfee VirusScan Enterprise 8.5 latest Patch is 8.
McAfee Host Intrusion Prevention 7.0 latest Patch is 6.
188.8.131.52 sounds like you are using Patch 5 for VirusScan 8.5. This is unsupported. The minimum supported Patch is 8.
Please ensure you test the Patches before deploying. Deploy to a small number of machines at any one time, just in case you come across any difficulty then this would be easier to manage as the scope of the issue would be small.
