Ads are delivered in the form of search-related ads, banner and video ads, in-text ads and links, transitional, interstitial and full page ads. Ads and features that appear on websites using this adware plugin are not associated with the underlying website the user is currently visiting and are injected. These ads are typically injected in the header of footer are of the web page. It will also convert words on pages you view into hyperlinks that are linked to advertisements.

Typically most users end up uninstalling this just after a few days. The software installer includes 12 files and is usually about 2.73 MB (2,861,499 bytes).

Crossrider extensions include background processes to monitor, update and automatically download new features/code without direct user interaction.
