Checking the size of full.zip files indicated in the errors above shows that its is not of correct size.

Cause

Corrupted full.zip file exists in database and in \Program Files (x86)\Symantec\Symantec Endpoint Protection Manager\Inetpub\content folder.
The file/s may exist in several monikers.
The existance of the corrupted files prevents Liveupdate from replacing the files.

Resolution

1. Review SEPM logs for Delta creation errors to obtain monikers to check for corruption.
2. Open a case with Broadcom Support to obtain ContentCleanupTool to remove the corrupt definitions from database and SEPM content folders.
3. Run SEPM Liveupdate to download updated definitions.
