Note that many websites have their own advertising, unrelated to adware.
From the Website:
The ClockSync! software bundle from WhenU.com includes both Save! and ClockSync.
By downloading the Save/SaveNow software ("the software"), you give permission to WhenU.com ("WhenU") to display relevant contextual information and offers. The software selects which ads and offers to show you based on several factors, including: which Web pages you visit, search terms you use while searching online, content of the Web pages you view and your local zip code (if you have supplied it).
The software protects your privacy by uploading a database of content in small chunks to your desktop and then determining on your desktop whether to retrieve information from WhenU or third-party servers. To protect your privacy, the same database of content is sent to all desktops. Decisions regarding which ads to retrieve to an individual desktop are all processed on the individual user's desktop - and isolated from WhenU servers. In this way, WhenU is able to deliver to you relevant coupons, information and advertisements without sending all of your browsing activity back to WhenU and without establishing any profile about you (even anonymously) on WhenU servers.
Note: WhenU has made changes in distribution practices and to our knowledge no longer uses third parties or bundling to distribute their application. Distribution appears to be in-house only and bundles only contain WhenU products. Research shows that WhenU now makes it clear that advertising will be shown in the End-User License Agreement (EULA)
Users who desire this shopping application should not remove.
