I am not sure I understand what you mean by an MD5 setting? What is it that you are trying to validate? MD5 is a type of hash that you can use to compare against a known MD5 value to see if the binary/package is corrupt or not, like when you download a file off of our FileConnect site, we use SHA-1 hashes.

You can get some more information on MD5 just by search the web if you need and checking out some of the Wiki articles.

Hello,

I believe, you want to say is "From where to check the virus definition is proper updated or not??" 

To check if the Latest definitions are installed on the machine, you can check this website:

Here you can click ont he Dropdown and click on Symantec Endpoint Protection 11.x -12.0 (32 bit)

Hope that helps!!

My Security admin question me that where the md5 setting avail in Server.

Senior questioned me that if any defintion will come in server with corrupted/virus then how to find it.??

Rafeeq is spot on with regards to Digital Signing. But I am also curious about how the content is validated. The logs probably validate upon download but what if you wanted to validate after download to see if the content is corrupt? I'm still trying to research and understand this as well.

As far as validating MD5 values on an Intelligent Updater file, that is easy. You can see the MD5 hash online at Security Response. You then download the file and run an MD5 validation against it like my example below:

By clicking on "all", you will get a more complete list of MD5 values.
