SlimComputer removes trialware, adware, toolbars, unwanted start-up entries and other unnecessary items from a PC. SlimComputer uses cloud technology and community feedback to provide recommendations about which programs on a PC are unneeded. Using real-time scanning and a live stream to a community-sourced data cloud, SlimComputer evaluates items on a PC and offers customized recommendations to improve PC performance. With one click of the run scan button in the SlimComputer main window, consumers receive information about which software, start-up items and toolbars are considered optional on their PC. The interactive assessments from the SlimComputer, user-based community provide information about the function and usefulness of each item on an individual PC. Users can receive and make recommendations about various pieces of software and rate applications all within the SlimComputer program. This community-based feedback and social infrastructure system separates SlimComputer from other PC cleaning and utility programs. User ratings make up a network of community-sourced data.
