The update file that needs to be downloaded is quite big,a bout 12 MB, and during the process the progress indicator will stay at 30% for quite a while. So, when the download is going slow it may look like it is not doing a thing.
Keep the updater running and wait. When it is not working after half a day bump this topic again.
I uderstand now it is because of the database is 12MB big and need the time to download. But before I upgrade the CIS to 3.9, everything was fine, the virus database upgraded very quickly.
I have seen the hint of “Virus Database is being updated” for a few times. And always shows “Failed to update the virus signature database. Please check the internet connection and try again later.” after I click the hint. It’s seems can not find the server which the database be downloaded from.
It had me worried when it seemed to stick at 30% . However I could see from my Netmeter that it was downloading still .After about 10 minutes it started moving on from 30% .As previously stated it is a huge update file .
