Ever wonder how to clean out your computer? Many people do, because it's not unusual to have your PC filled with adware, toolbars and other programs you no longer need or probably never intended to install in the first place.
Should I Remove It? is a very simple but extremely powerful Windows application that helps users, both technical and non technical, decide what programs they should remove from their PC. This typically includes finding and removing all sorts of crapware and bloatware such as adware, spyware, toolbars, bundled unwanted applications as well as many forms of malware. The program is very lightweight and extremely fast. Should I Remove It? simply scans your computer for all its' installed programs and then ranks what should be removed by leveraging the wisdom of the crowd (and of course our technical experts) to determine what should not be installed.
