ARO scans 3 main areas: Registry, Junk and Security. The registry scan analyzes 13 areas of the Windows registry for errors and identifies possible registry tweaks that can help improve PC performance. The junk scan checks 10 areas of the PC for clutter, freeing up disk space by identifying and removing extraneous files that can clutter and slow down a system. It also scans and removes junk accumulated from web browsers including: temporary internet files, cookies, download history and form data/passwords. The baseline security scan confirms a user has up-to-date security software including antivirus, antispyware, and firewall and now also verifies that updates for key PC applications, such as the Windows operating system, Adobe or Java are properly configured and turned on.
