The error occurs when the Anti-Malware (AM) function for Deep Security Virtual Appliance is enabled.
To resolve the issue, follow the steps below:
- Go to Policies > Deep Security Virtual Appliance policy > Details.
- Choose Anti-Malware.
- On the General tab, turn off Anti-Malware State.
- Save the changes.
- Go to Computers and find the Deep Security Virtual Appliance.
- Right-click the selected Deep Security Virtual Appliance and click Actions > Send Policies.
- Once again, select the Deep Security Virtual Appliance and click Actions > Clear Warning / Errors.
Deep Security Manager will now send the new policy along with the disabled Anti-Malware to the Deep Security Virtual Appliance. In return, the offline status will not occur anymore.
Note that Deep Security Virtual Appliance should not be applied as an Anti-Malware policy and should only be activated on the virtual machine protected by Deep Security Virtual Appliance.
