Need a DOS command to find update date of Symantec Antivirus

Hello to all,

We have Symantec endpoint manager in our organisation having approx. 1500 end users on symantec managed clients.

I have been making a script in C that will do alots of jobs for displaying the info about system. In view of that I need to find out the last updation date of Symantec anti virus on client machine.

this script will run on every client computer. It will use DOS command to find out the latest updation date of Symantec anti virus.

So,is there any DOS command to display the updation date of :-

1.  Antivirus and Spyware protection

2.  Proactive threat

3.  Network threat

Thanks...
