Explanation :
ErrorSafe has the following strategy: He gets installed either by the user or by some other application like a downloader.
They start scanning the system as soon as you install them and then report to you a series of system critical errors that need fixing and tell you to buy the application if you want it to fix your errors. Even on a clean windows installation these programs report threats and errors.
