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



It deletes the initially executed copy of itself.

– Temporary files that might be deleted afterwards:
   • %TEMPDIR%\1.reg
   • %system drive root%\a.bat

 Registry The following registry keys are added in order to run the processes after reboot:
