    Virus Scan 8.7 issue on Hyper V

      Hi,

       

      Does anyone had issues on having VSE 8.7i installed on a Hyper-V machine?? Because we had an issue where Mcshield hogged 100% CPU Usage when opening a virtual machine.

       

      Any suggestions?

          We have 8.7i installed on our Hyper-V.  The key is making sure On-Access protection is NOT scanning vm files.  As a rule on our vm's we have OAS turned off, but have nightly scans scheduled.  If this is a production machine, you may not be able to get away with it, but our VM's are quasi production/dev platforms.

           

          EDIT: (note) I believe I read something about this in the documentation as well.

            I have the exact same problem. Happens on most virtual machines, not all. Doesn't happen on virtual machines that are stored on a standalone Hyper-V server where the VM is on a local RAID-5. However does happen I believe on all VMs that are on our Clustered Hyper-V servers. They are on a CSV on our SAN and I have the CSV excluded from scanning. Every time the machine is booted or Mcshield is restarted then Mcshield.exe will take up alot of CPU and slow the machine down. I followed Microsoft's recommendations for which directories and files to exclude on all of our nodes in our cluster.

              We are satisfied with the following configuration (HyperV 2008 R2 Cluster):

               

               

              OAS - on ... with nearly all options activated, except scanning of network locations - wich resulted in big problems, while VSE "blocks" some files while starting a virtual machine..

               

              our exclusions:

              *.hive
              *.container
              *.blf

              C:\ProgramData\Microsoft\Windows\Hyper-V\

              C:\Users\Public\Documents\Hyper-V\Virtual Hard Disks\

              C:\Clusterstorage\

              *.VHD
              *.VUD
              *.VSV

               

              As for now, we don't feel performance issues or any other negativ impact.

               

              Regards

              Daniel
