Bootton usually arrives on a phone disguised as a SIS installer for normal applications or dropped by other malwares. When this malicious SIS package is executed, it overwrites normal application files in the device’s C drive with copies that, when executed, restarts the compromised device. Some of the popular applications it disables in this way include the following:

To disinfect a compromised device, it is necessary to reinstall all overwritten applications. The SymbOS/Bootton SIS installer must then be deleted. If this does not restore the phone, a formatting the phone may be necessary. All data saved in the C drive will be lost during a format.
