Next, it creates the following registry entry:
  • HKEY_LOCAL_MACHINE\SOFTWARE\SystemOptimizerPro\"UID" = "{15923B19-1EF2-473F-A034-5765014D1A84}"

It also creates the following registry subkeys:
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\SystemOptimizerPro.exe
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\System Optimizer Pro
  • HKEY_LOCAL_MACHINE\SOFTWARE\SystemOptimizerPro

When the application is executed, it will perform a scan of the computer.



When the scan is complete, the application displays a list of problems it claims to have found on the computer.



If the user chooses to fix the issues, the application asks the user to register and subscribe to the full version.



Once the user registers with an email address, they are redirected to the following remote location:
  • [https://]secure.securewebpayments.com/systemoptimize[REMOVED]

The web page the user is shown offers them a "Limited time offer" that expires on a specific date. However, the application obtains this date by checking the current date of the computer it is installed on.



The application's settings cannot be modified as the setting menu is empty.
