Mcafee Process Validation Service high disk usage

Jump to solution

Hi, 
We have a user with Windows 10. A c: and d: drive.

When he access a large file area on the d:\drive - the mcafee process validation service processes max's out the disk usage and makes the machine useless until a reboot. 

Any suggestions? 

EpO and ENS with Threat Pervention

And we have the folders excluded from scanning. 

Thanks

I don't thing this problem belong to OS issue. After uninstall and re-install ENS on this machine (Agent still installed), McAfee Process Validation Service working with no problem.
With my additonal issues above, 1st can be resolved by re-install McAfee agent using flowing process (taking it one or more times):
"Go to System Tree -> Select Target System -> Actions -> Agent -> Deploy Agents". Problem is client not listening on port 8081.

Are you using ENSFW? If yes, please ensure you don't have log all allowed traffic enabled.

Further you may also want to check your logging settings with the ENS Common policy - if you have everything set to log, try reducing what you are logging.

Similarly if you see many access protection events on the system, this may also trigger this behaviour.

In my case, ENSFW not installed.

ENS Common policy set to log everything with "Critical anf Alert" level on Client Logging. But all events send to McAfee ePO, not store in Windows Events log.

Device with this problem only use Microsoft Office 365, Adobe Acrobat DC/Reader and Browser.

Additional,I have some issue with McAfee.

1, I'm upgrading all client agent from 5.6.0.447 to 5.6.0.702 version using Product Deployment task. But some device cannot upgrade with unknown reason. Firewall is off, not install other AV product.

2, Some device cannot install Endpoint Security Adaptive Threat Protection and Endpoint Security Threat Protection modules. It only installed Endpoint Security Common and Web Control. Client devices using Windows 10 Profestional 64bit, version 1703/1709/1803/1809.

This is interesting. 

O365 is installed on this machine too. 
There is a known 'file open' issue that MS is looking into. It may be a red-herring, or it may be related.

Either way, I also commented on this similar thread:

https://community.mcafee.com/t5/Endpoint-Security-ENS/Query-on-mfetp-exe/m-p/624765#M3919

 

Support believes it to be an OS issue at this time.

Windows 10 without an SSD is a nightmare. Especially the first days when all updates are done, systems with HDDs are practically unusable. It doesn't get much better after, either. Upgrade to an SSD (a small one just for the OS, any brand, any price), otherwise use Win7.
