Behavior
The program must be manually installed and executed.

The application reports a number of exaggerated reports on the computer.



The user is then prompted to pay for a full license of the application in order to remove the falsely reported threats.



Installation
When the program is execued, it creates the following files:
%UserProfile%\Desktop\CrisysTec Sentry 3.0.lnk
%UserProfile%\Start Menu\Programs\CrisysTec Sentry\CrisysTec Sentry Help file.lnk
%UserProfile%\Start Menu\Programs\CrisysTec Sentry\CrisysTec Sentry.lnk
%UserProfile%\Start Menu\Programs\CrisysTec Sentry\Uninstall CrisysTec Sentry.lnk
%ProgramFiles%\Critical Systems Technologies\CrisysTec Sentry\BSwap.exe
%ProgramFiles%\Critical Systems Technologies\CrisysTec Sentry\INSTALL.LOG
%ProgramFiles%\Critical Systems Technologies\CrisysTec Sentry\install.sss
%ProgramFiles%\Critical Systems Technologies\CrisysTec Sentry\Plugins\Extensions.plugin_example
%ProgramFiles%\Critical Systems Technologies\CrisysTec Sentry\Plugins\Extensions83.plugin

%ProgramFiles%\Critical Systems Technologies\CrisysTec Sentry\Sentry.chm
%ProgramFiles%\Critical Systems Technologies\CrisysTec Sentry\Sentry.exe
%ProgramFiles%\Critical Systems Technologies\CrisysTec Sentry\Uninstall.exe

Next, the program creates the following registry entry so that it executes whenever Window starts:
HKEY_ALL_USERS\Software\Microsoft\Windows\CurrentVersion\Run\"CrisysTec Sentry" = "C:\Program Files\Critical Systems Technologies\CrisysTec Sentry\Sentry.exe -Minimized"

It also creates the following registry subkeys:
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\Shell
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{34BCE26E-D9F8-46CB-8A59-B473A14471F0}
HKEY_ALL_USERS\Software\Critical Systems Technologies
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SharedDlls\C:\Program Files\Critical Systems Technologies\CrisysTec Sentry\Uninstall.exe

The program also modifies the following entries:
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\"(Default)" = "CrisysTec Protected Recycle Bin"
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\LocalizedString\"(Default)" = "CrisysTec Protected Recycle Bin"
