Symantec databases update programmatically

Hi,

I need to run DoScan.exe utility from my C# code to scan uploaded files.

I installed Symantec Endpoint Protection (SEP) to Azure Worker Role through command line.

It requires reboot after installation. So I reboot VM immediately after SEP installation.

But after reboot during 6 minutes SEP is unavailable. I think it finishing installation and database updates.

How I can be sure that SEP finished his installation and ready to work steps programmatically?

How I can ensure that virus databases is up to date programmatically?

Can I run databases update programmatically?

After virus databases installation sometimes it requires reboot. How I can get this information?
