The program may be silently installed on the computer through PUA.OpenSwUpdater .

When the program is executed, it creates the following folders:
  • %ProgramFiles%\InstantSupport
  • %ProgramFiles%\InstantSupport\languages
  • %ProgramFiles%\PCAcceleratePro
  • %ProgramFiles%\PCAcceleratePro\languages

Next, the program creates the following files:
  • %Windir%\Prefetch\PCACCELERATEPRO.EXE-3A51289D.pf
  • %ProgramFiles%\InstantSupport\1.txt
  • %ProgramFiles%\InstantSupport\helper.exe
  • %ProgramFiles%\InstantSupport\InstantSupport.dll
  • %ProgramFiles%\InstantSupport\InstantSupport.exe
  • %ProgramFiles%\InstantSupport\languages\english.lng
  • %ProgramFiles%\InstantSupport\languages\russian.lng
  • %ProgramFiles%\InstantSupport\uninstall.exe
  • %ProgramFiles%\PCAcceleratePro\1.txt
  • %ProgramFiles%\PCAcceleratePro\ap.ico
  • %ProgramFiles%\PCAcceleratePro\data
  • %ProgramFiles%\PCAcceleratePro\helper.exe
  • %ProgramFiles%\PCAcceleratePro\ISSetup.exe
  • %ProgramFiles%\PCAcceleratePro\languages\english.lng
  • %ProgramFiles%\PCAcceleratePro\languages\russian.lng
  • %ProgramFiles%\PCAcceleratePro\PCAcceleratePro.exe
  • %ProgramFiles%\PCAcceleratePro\PCAccelerateProAS.exe
  • %ProgramFiles%\PCAcceleratePro\uninstall.exe

The program then creates the following registry subkeys:
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{480ED1A4-0C5C-43bA-AD0E-A9CEA7A51A5E}

Many risks make modifications to the registry, which could impact the functionality or performance of the compromised computer. While many of these modifications can be restored through various Windows components, it may be necessary to edit the registry. See in the Technical Details of this writeup for information about which registry keys were created or modified. Delete registry subkeys and entries created by the risk and return all modified registry entries to their previous values.
