When the program is installed, it creates the following files:
  • %Windir%\system32\roboot.exe
  • %Windir%\system32\sasnative32.exe
  • %AllUsersProfile%\Application Data\Systweak\Advanced System~Protector\log.xslt
  • %AllUsersProfile%\Desktop\Advanced System Optimizer.lnk

Next, the program creates the following folders:
  • %ProgramFiles%\Advanced System Optimizer 3
  • %AllUsersProfile%\Start Menu\Programs\Advanced System Optimizer 3

The program then creates the following registry entries:
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\*\ShellEx\ContextMenuHandlers\"SecureExt" = "{D23C3BA7-6DC3-4DDF-9BDF-12599E852A40}"
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AppID\SecureShell.dll\"AppID" = "{C42CB13B-CA97-468D-9F93-AD1220004E62}"
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AppID\"{C42CB13B-CA97-468D-9F93-AD1220004E62}" = "SecureShell"

  • HKEY_CURRENT_USER\Software\Licenses\"{IF8356A249F37E323}" = "17000000"
  • HKEY_CURRENT_USER\Software\Licenses\"{0F8356A249F37E323}" = "[HEXADECIMAL VALUE]"

Next, the program creates the following registry subkeys:
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{B0F3F4F9-CB76-9A52-9442-B481A5FF49D3}
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{D23C3BA7-6DC3-4DDF-9BDF-12599E852A40}
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Interface\{C99650F6-688D-4BAB-86E4-BC045EF0FFBF}
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\SecureShell.SecureShellExt
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\SecureShell.SecureShellExt.1

  • HKEY_LOCAL_MACHINE\SOFTWARE\systweak\aso3
  • HKEY_CURRENT_USER\Software\systweak\aso3\
  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ASO3DiskOptimizer

The program then performs the following actions:
