  which is achieved by overwriting the data with pseudorandom numbers generated by Mersenne twister or ISAAC. 
  The Gutmann method, Quick Erase, DoD Short (3 passes), and DOD 5220.22-M (7 passes) are also included as options
  to handle data remanence

  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.
