Hi IdrisEzzy,

This might be a known issue.  Can you read this article and see if the matches what you are seeing?

If it is that issue, SEP 12.1 RU2 will fix it.

With thanks and best regards,

Configure the Disk space Management for Virus Def.

To configure the disk space used for LiveUpdate downloads

  1. In the console, click Admin.

  2. Click Servers and select the site that you want to configure.

  3. Under Tasks, click Edit Site Properties, and then click LiveUpdate.

  4. Under Disk Space Management for Downloads, type the number of content downloads that you want to store.

  5. If you want to reduce the amount of disk space used, uncheck the Store client packages unzipped to provide better network performance for upgrades option. Note: Disabling this option also disables the ability of Symantec Endpoint Protection Manager to construct deltas between content revisions and may adversely affect network performance for updates.

  6. Click OK.

I understand that you are talking about the SEP client not the SEPM. By default SEP 12.1 client stores only 1 definitions.

Could you provide us the path of the virus defs folder?
