 Files It copies itself to the following location:
   • %SYSDIR%\swchost.exe



It deletes the initially executed copy of itself.

 Registry The following registry keys are continuously in an infinite loop added in order to run the processes after reboot.

–  [HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices]
   • "winbin"="swchost.exe"

–  [HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
   • "winbin"="swchost.exe"

–  [HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
   • "winbin"="swchost.exe"

–  [HKCU\Software\Microsoft\Windows\CurrentVersion\RunServices]
   • "winbin"="swchost.exe"



The following registry keys are added:

– [HKLM\SOFTWARE\Microsoft\Ole]
