Behavior

PUA.SparksSupportdoc is a potentially unwanted application that installs another application and modifies browser settings without user consent.

Once executed, the application creates the following folders:
  • %ProgramFiles%\Support Doc
  • %ProgramFiles%\Support Doc\InetSpeed
  • %ProgramFiles%\Support Doc\InetSpeed\de
  • %ProgramFiles%\Support Doc\InetSpeed\en
  • %ProgramFiles%\Support Doc\Notification

The application creates the following files:
  • %ProgramFiles%\Support Doc\addPrg.xml
  • %ProgramFiles%\Support Doc\b.bat
  • %ProgramFiles%\Support Doc\CircularProgressBar.dll
  • %ProgramFiles%\Support Doc\favicon.ico
  • %ProgramFiles%\Support Doc\InetSpeed\de\i-net_speed_booster.resources.dll
  • %ProgramFiles%\Support Doc\InetSpeed\en\i-net_speed_booster.resources.dll
  • %ProgramFiles%\Support Doc\InetSpeed\Help.chm
  • %ProgramFiles%\Support Doc\InetSpeed\i-net_speed_booster.exe
  • %ProgramFiles%\Support Doc\InetSpeed\Microsoft.Win32.TaskScheduler.dll
  • %ProgramFiles%\Support Doc\InetSpeed\NetworkMonitor.dll
  • %ProgramFiles%\Support Doc\InetSpeed\voice.wav
  • %ProgramFiles%\Support Doc\Interop.Shell32.dll
  • %ProgramFiles%\Support Doc\livechat.html
  • %ProgramFiles%\Support Doc\Microsoft.Win32.TaskScheduler.dll
  • %ProgramFiles%\Support Doc\Notification\notificationtone.wav
  • %ProgramFiles%\Support Doc\packagedetail.xml
  • %ProgramFiles%\Support Doc\Support_Doc.exe
  • %ProgramFiles%\Support Doc\Support_Doc.exe.config
  • %ProgramFiles%\Support Doc\Support_Doc.pdb
  • %ProgramFiles%\Support Doc\Support_Doc.vshost.exe
  • %ProgramFiles%\Support Doc\Support_Doc.vshost.exe.config
  • %ProgramFiles%\Support Doc\Support_Doc.vshost.exe.manifest
  • %ProgramFiles%\Support Doc\unins000.dat
  • %ProgramFiles%\Support Doc\unins000.exe
  • %ProgramFiles%\Support Doc\unins000.msg
  • %AllUsersProfile%\Microsoft\RAC\Temp\sqlD9C9.tmp
  • %AllUsersProfile%\Microsoft\RAC\Temp\sqlD9CA.tmp
  • %AllUsersProfile%\Microsoft\Windows\Start Menu\Programs\Support Doc\Support Doc.lnk
  • %AllUsersProfile%\Microsoft\Windows\Start Menu\Programs\Support Doc\Uninstall Support Doc.lnk
  • %AllUsersProfile%\Public\Desktop\Support Doc.lnk

The application then creates the following registry subkeys:
  • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\SupportDoc
  • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\SupportDoc\Info

Next, the application creates the following registry entries:
  • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{6406DF9F-J9K3-4C2E-AB48-33333BDF7777}_is1\"DisplayIcon" = "%ProgramFiles%\Support Doc\favicon.ico"
  • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{6406DF9F-J9K3-4C2E-AB48-33333BDF7777}_is1\"Inno Setup: Icon Group" = "Support Doc"
  • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{6406DF9F-J9K3-4C2E-AB48-33333BDF7777}_is1\"Inno Setup: App Path" = "%ProgramFiles%\Support Doc"
  • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{6406DF9F-J9K3-4C2E-AB48-33333BDF7777}_is1\"UninstallString" = ""%ProgramFiles%\Support Doc\unins000.exe""
  • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{6406DF9F-J9K3-4C2E-AB48-33333BDF7777}_is1\"QuietUninstallString" = ""%ProgramFiles%\Support Doc\unins000.exe" /SILENT"
  • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\SupportDoc\Info\"IsTrackSupportDoc" = "1"
  • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\SupportDoc\Info\"Program" = "SupportDoc"

The application installs another application without user consent.

The application also changes the browser's default search provider and homepage to the following:
