Directory where SEP 12 RU2 clients keeps AV Definitions

Created: 06 Mar 2013 • Updated: 11 Mar 2013 | 4 comments
This issue has been solved. See solution.

Our Engineers are creating new images that include SEP 12 RU2 clients. But they take nearly 4 GB of space. Which directory path holds the SEP AV definitions. That way, they can delete the SEP AV definitions and once the image is deployed, the SEP client can contact the SEPM and download definitions.

The Engineers want to keep the image as small as possible.

Thank you

SEp clients definitions should not take that much space = default amount of revisions kept on the client should be only 1 - that would not make more than 400MB. Do you see all 4gb occupied in the folders mentioned by Brian?

Can you check which folder is taking space more than 400/500 MB?

Ideally it should not take 4 GB disk space.

Make sure SEP clients definitions are not corrupted with the image machine itself.
