Hello,
I agree with pete and guwy above. "Thumbs up" to them.
Incase, if you are carrying a Symantec Endpoint Protection (Enterprise Edition), when the Paid License Expires /Upgrade licenses: After the end date the capability of submitting samples and data to Insight is revoked but the content updates are still available. The client works as usual, no warning on the client side.
Check the Attachment.
That would clear your doubts.
