Disabling the Anti-Malware Periodic Scan

"Anti-Malware Scan Storms" can occur when anti-virus scans run at the same time on multiple virtual machines on the same physical server.

A degradation of system performance is possible that can affect disk I/O and CPU usage.

We recommend that you disable the Anti-Malware periodic scan in one of these ways:

  1. In Endpoint Web Management

    1. Go to the Policy Page.

    2. In the right pane, click Web & Files Protection.

    3. In the Perform periodic scan every field, select Never.

    4. Click Save.

    5. Install policy.

  2. Configure the Windows Registry settings on the client machine

    To configure the Windows Registry settings on the client machine:

    1. In Windows Registry, configure the value 0x0b for the AVSchedOf key:

      • On 64-bit operating system:

        HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\CheckPoint\EndPoint Security\Anti-Malware\AVSchedOf=(DWORD)0x0b

      • On 32-bit operating system:

        HKEY_LOCAL_MACHINE\SOFTWARE\CheckPoint\EndPoint Security\Anti-Malware\AVSchedOf=(DWORD)0x0b

    2. Restart the machine to restore Self-Protection.

      Use the Compliance Software Blade to change the registry. See sk132932.

Advanced Settings for Persistent Desktops

  1. Disable the Anti-Malware Periodic Scan. See the instructions above.
  2. If you cannot disable the Anti-Malware Periodic Scan, then enable the Anti-Malware Randomized Scan.
    1. Connect with the Database Tool (GuiDBEdit Tool) (sk13009) to the Endpoint Security Management Server.
    2. Configure the value true for the attribute enable_randomized_scan.
    3. Configure the value true for the attribute enable_schedular_scan.
    4. Configure the applicable value for the attribute scan_interval.

  3. In SmartEndpoint, install policy.

Advanced Settings Non-Persistent Desktops

This section shows how to configure clients manually for the Non-Persistent VDI solution in the Signature Server and Signature Server Consumers roles.

Use this approach if the "Policy Approach" is not available.

You can configure the Signature Server manually or with a script. To configure the Shared Signatures Server:

Manually

Create a Shared Folder

  1. Create a folder to store the shared signatures.
  2. Share the folder and grant read access to members of the Domain Computers' group.
    Note:
    On Workgroup machines, the "SYSTEM" account does not have network login rights. This configuration is not supported.

Configure the Windows Registry Keys

  1. Configure the value 0x01 for the key VdiSignatureServer (to configure the machine as "Shared Signatures Server"):

    • On 64-bit operating system:

      HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\CheckPoint\Endpoint Security\Anti-Malware\VdiSignatureServer=(DWORD)0x01

    • On 32-bit operating system:

      HKEY_LOCAL_MACHINE\SOFTWARE\CheckPoint\Endpoint Security\Anti-Malware\VdiSignatureServer=(DWORD)0x01
  2. Configure the path to the shared signatures folder in the key AVSharedBases:

    • On 64-bit operating system:

      HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\CheckPoint\Endpoint Security\Anti-Malware\AVSharedBases=(SZ)"DISK:\\Path\\To\\Shared\\Folder"

    • On 32-bit operating system:

      HKEY_LOCAL_MACHINE\SOFTWARE\CheckPoint\Endpoint Security\Anti-Malware\AVSharedBases=(SZ)"DISK:\\Path\\To\\Shared\\Folder"
    Important:

    If you do not configure the path, then the default shared folder is:

    C:\ProgramData\CheckPoint\Endpoint Security\Anti-Malware\bases\shared

    The default shared folder exists after the first successful update.

  3. Reboot the machine to restart the Anti-Malware blade.

Configuration with the Script

  1. Download the Shared Signatures Server Configuration script file.
  2. Execute the script on the Signature Server and follow the instructions.
  3. Make sure the script finishes successfully.
  4. Make sure you reboot the machine to restart the Anti-Malware blade.

Configuring the Client Machine

You can configure the Client Machine (the Golden Image) manually or with a script.

Manually

  1. Configure the value 0x01 for the key VdiSignatureServer (to configure the machine as "Shared Signatures Server"):

    • On 64-bit operating system:

      HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\CheckPoint\Endpoint Security\Anti-Malware\VdiSignatureServer=(DWORD)0x01

    • On 32-bit operating system:

      HKEY_LOCAL_MACHINE\SOFTWARE\CheckPoint\Endpoint Security\Anti-Malware\VdiSignatureServer=(DWORD)0x01
  2. Configure the path to the shared signatures folder in the key AVSharedBases:

    • On 64-bit operating system:

      HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\CheckPoint\Endpoint Security\Anti-Malware\AVSharedBases=(SZ)"DISK:\\Path\\To\\Shared\\Folder"

    • On 32-bit operating system:

      HKEY_LOCAL_MACHINE\SOFTWARE\CheckPoint\Endpoint Security\Anti-Malware\AVSharedBases=(SZ)"DISK:\\Path\\To\\Shared\\Folder"
    Important:

    If you do not configure the path, then the default shared folder is:

    C:\ProgramData\CheckPoint\Endpoint Security\Anti-Malware\bases\shared

    The default shared folder exists after the first successful update.

  3. Reboot the machine to restart the Anti-Malware blade.

Configuration with the Script

  1. Download the Golden Image Configuration script file.
  2. Execute the script on the Golden Image and follow the instructions.
  3. Make sure the machine is rebooted.
