Explanation :
Cabir.Dropper is Symbian installation file that will install Cabir.B, Cabir.C and Cabir.D into the device and disables the Bluetooth control application. The original version of Cabir.Dropper is named Norton AntiVirus 2004 Professional.sis.The Cabir.Dropper installs different Cabir variants into several places in the device file system. Some of the installed Cabirs replace common third party applications so that if user has one of those applications installed into system it gets replaced with Cabir.D and it's Icon in the menu will go blank. If user clicks on one of the replaced icons in the menu, the Cabir.D that has replaced that application will start and try to spread to other devices. If Cabir.D starts it will spread as Cabir.D ([YUAN].SIS) without other Cabir variants or Cabir.Dropper. The Cabir.Dropper will also install autostart component that tries to automatically start Cabir.D upon system reboot, but fails as the autostart component points into directory that is not installed on the device.
