Skudoo.B also drops several Cabir variants on the phone and component files Doomboot.A trojan.

The Doomboot component dropped by Skudoo.B prevents phone from rebooting, so if your phone is infected with Skudoo.B, it is critical not to reboot the phone.

As Skudoo.B breaks the application manager and application installer, the only currently working method of disinfection works with phones that have removable memory card.
