How to stop Norton and AVG AntiVirus from blocking CDM+ processes

A May 2025 update to both Norton Antivirus and AVG is not compatible with CDM+. This article will outline the steps needed to workaround this issue.

AntiVirus quarantines a valid file and CDM+ locks up

Certain operations in CDM+, such as opening a report window or updating, can prompt the AntiVirus software to display a quarantine message relating to suran_script_wrapper.

Once this message appears CDM+ will lock up and must be terminated.

(Secondary Symptom) Binding Omnis Server socket spins indefinitely or fails

Once the quarantine message appears, subsequent launches of CDM+ can display a message “Binding Omnis Server socket…”

If you hit cancel on this popup the process will fail and a trace log will appear. You will then be prompted to login as normal.

How to resolve these issues

Both issues can be resolved with the following workaround:

1. Open your antivirus software

2. Go to settings and follow the path for your antivirus software:

   1. For Norton:

      1. Security → Advanced Security → Antivirus → Exclusions

   2. For AVG

      1. Menu → Settings → Exceptions

3. Add a new exception/exclusion

4. Choose File/Folder

5. Click the folder icon to browse for the path

6. Go to This PC → Local Disk (C:) → Users → (your user) → AppData → Local → Temp

7. Check suran

8. Click ok to add the exception

9. If you are warned about the exception being too broad, bypass the warning and add anyway

You can now use CDM+ normally.

If you still receive the error Binding Omnis Server socket reboot your computer to resolve this.
