SymbOS.Bootton.E is a Trojan horse that restarts the mobile device when executed. It also drops corrupted components that cause the reboot to fail. The Trojan runs on the Symbian OS, which is used as the operating system for Nokia Series 60 cellular telephones.

The Trojan reportedly arrives as Restart.S60.SIS. When the user clicks on the .sis file, the phone installer displays a dialog box to warn the user that the application may be coming from an untrusted source and may cause potential problems.
