Sophos on Citrix high cpu utilisation

ajsmith

I am finding significant performance problems with Sophos on our Citrix Xenapp 5 presentation servers (W2k3).  I have recently been seeing very high CPU utilisation - 50%+ for prolonged periods which is killing performance on the servers.  I have a seperate policy for the Citrix servers which includes windows exclusions for the Citrix program folder, UNC for roaming profiles, and the page file drive.  Can anyone share best practice for a successful deployment on Citrix or experience of similar problems and how they can be overcome?

Thanks.

    Hi,

    Can you paste here the exclusion list you have so we can check it?

    Also what AV options do you have? 

    Configure - Anti-Virus  - On-access Scanning
    On-Read:
    On-Write:
    On-Rename:
    Scan inside archive files:
    Scan All files:
    Scan for suspicious:
    Scan for adware puas:

    Configure - Anti-Virus - Suspicious behaviour detection
    Detect suspicious behaviour: 

    Detect buffer overflows:
