The redesigned user interface improvements include more flexibility and control. This includes user-defined file sizes, which speeds up the scanning process by excluding files it recognizes as clean. Other advanced features include automatic quarantine and Recycle Bin storage of removed components, an all-new viewer for backup archives that allows you to quickly and easily review components that have been removed and stored for future restoration, and an integrated reference file updater that can automatically search for new reference files when Ad-aware is started. The latest version includes improved Browser Hijacker detection, hosts file scanning, and a Smart Scan mode that improves speed and has been optimized to detect content at the root. Be aware that some ad-supported programs, such as GoZilla Free, will no longer function if you remove their ad modules.
