MacScoop readers noticed Apple has quietly posted on its web site a new ad part of its "Get-A-Mac" campaign.

This new ad could be called « Cancel or Allow » as it highlights Vista’s new hacking protection feature which consists of prompting users on any action they make.

The Mac introduces himself like usually while the PC is interrupted by a « Cancel or allow » message coming from a security agent who’s back to him.

The ad is not available in Apple's "Get-A-Mac" campaign site yet but should be shortly made visible.
