Citrix PVS and Antivirus exclusions

Home / Citrix / Citrix PVS and Antivirus exclusions

On a number of implementations that I’ve seen there is a lack of correct antivirus exclusions which can cause stability issues. Unfortunately it happens more often than one would expect and I have therefore decided to document the once that most people are missing.

It should be noted that there are some different file names for various OS, and that some files doesn’t exist for some versions. I have tried to document everything as good as possible based upon some notes that I have taken over the years – however I still recommend that you review the recommendation below so they actually match your system. It should also be noted that some of the exclusions depends for example on the setup used, default paths, operating systems in combination with product version etc.

A few recommended Server Side file exclusions.

C:WindowsSystem32driversCVhdBusP6.sys => (PVS 6.1)
C:WindowsSystem32driversCVhdBus2.sys => (PVS 5.6)
