Hello,
We migrated to McAfee ENS 10.7 some weeks ago, since this migration, our Citrix team is complaining about performance issues and slowness (application / startup/ ...).
We implemented "best practices from Citrix KBs" (process and files/folders exclusions) and only scan on write.
It seems that this configuration is now the best.. Should we use "let McAfee decide" and trust all citrix certificates ?
Somebody who protect a citrix infrastructure (xendesktop and xenapp) with McAfee ENS 10.7 can give us advice / best config to minimize impact for users ?
Thanks !
Hello ,
Kindly use the option "let McAfee decide" and trust all citrix certificates. IF all the recommended standard exclusions are in place, there should be any issue .
Also with ENS 10.7 , Adaptive threat prevention also gets install , So you may disable that and check if that makes any difference .if so then i would recommend you to connect to McAfee Technical Support with Procmon data .
Thank you.
Hello,
Thanks for this answer,
With Let McAfee decide, did you also implement all process and folder exclusions from Citrix (ex : https://docs.citrix.com/en-us/tech-zone/build/tech-papers/antivirus-best-practices.html) ?
For the moment we didn't deploy ATP on Citrix infrastructure, they only complains about on-access scan which use too much CPU and seems to introduce slowness.
Also, sometimes mfevtp process use about 15 % CPU, how to check why ?
Thanks !
Hello,
I am experiencing this same issue with Citrix Xen Desktop 7.15 1912 LTSR and McAfee ENS 10.7 On-Access Scan policy. There is a lag during our log on sessions to Citrix. When the OAS is disabled there is no lag at all. I allowed the Citrix certificate and set the ENS On-Access Scan policy to write to disk instead of selecting let McAfee decide. I have added all the exclusions Citrix recommended for anti-virus, and still experience a lag when launching applications. Any suggestions would be help at this point.
ENS 10.7 April 2020 Update with Hotfix 199847, AMCORE 4245
We had this issue on 10.6. Is there still not a fix to it?
