Hi BMcC,
Lumion Demo 5.3 which is available via
the 'Try' link at the top of this page.
If you can confirm that this is where you got the
Download Manager from (after filling in the form and clicking on the link in the email that was sent to you), you can safely ignore the warning in Norton. The
Lumion Demo 5.3 Download Manager and installer from lumion3d.com are 100% safe.
