Built in on demand scan cannot be disabled after creating one.
I would suggest you to create a new sub-group under my organization in the system tree and move the computer the new group.
once you have moved the computer to the new group you can have a look at the assigned client tasks which will not show the default built in - on demand scan.
Now go to client task catalog > policy based on demand scan > click on assign in either full scan or quick scan and select the new sub-group that you have created> change the scan date and timings as per your convenience and it should work.
And also i would like to inform you that default built in does not comes with a editable option. its like parental document . Based on the default you can duplicate new one and assign to your computers.
Note: if you still have queries on ODS you can reach Tech support for better assistance
Wow that was actually helpful
I can now see where I went wrong. It was when creating a new deployment it is defaulted to "McAfee Default Policies and Tasks" on all accounts. So when creating a new deployment I have to have the policies in order beforehand, and then I can change the assignments on the deployment.
Thank you very much for the quick reply. It was very helpful
You are welcome. Its my pleasure to help you
