Hi,
I am sorrry, but i am not very sure where do you see 0% update.If it isnt too much of effor, can you please put a screen shot.
Also, mean while you can check with the following steps:
If you would like to see the progress on the clients, you will need to edit your antivirus policy to show the status of scans. To do this:
1. Go to Policies
2. Select your Antivirus and Antispyware policy.
3. Right click and choose edit.
4. Select Administrator-definied Scans.
5. Choose the Advanced tab.
6. Under the Advanced tab go to the bottom under Show Progress Options, click the drop-down box and choose Show scan progress or Show scan progress if risk detected.
