During one week eight Cardtrap Trojans for Symbian became known. They have different names but in general they delete different application from a cell phone. The Trojans are spread as applications for Symbian .SIS. Some versions of these Trojans infect phone, some PC to which the phone is connected, some install faulty font Fontal which leads to OS failure after the phone is reset. Therefore one should be careful as to applications one installs.
