Log what VSE is scanning during logon? Citrix is very slow because of VSE


We use ePo 5.9.1 and VSE 8.8 with Patch 11 on workstations and servers.

We have an issue with Citrix XenApp, when users log into their virtual desktops they will get a black screen for about 20-30 seconds and then their desktop will appear.

I've spent ages on the phone with Citrix support and nothing worked until we uninstall VSE, then logins were lighting fast.

I have followed this link but it didn't speed up things

Something else must be causing this with VSE. 

Is there anyway I can debug this log on to see what is being scanned?

Citrix issues such as the one you've reported are generally caused by missing exclusions. Here are the Citrix recommended exclusions - one of which you've mentioned already:

Citrix Guidelines for Antivirus Software Configuration (

Citrix Consolidated List of Antivirus Exclusions (


Make sure  you are using low/ high risk processes and not just standard exclusions. You should have those Citrix processes makred as low risk processes and you may need to disable scanning for low risk processes. 

To see what mcschield is doing though, you could use procmon:
