Users of Symbian Series 60 smart phones should be aware of a new Trojan horse that, if not removed within one hour, can cause complete data loss in their wireless devices, security experts warn. Several owners of Symbian-based handsets have caught the Trojan Doomboot.A. after downloading unauthorized mobile phone games containing the malware, says Anton Von Troyer, marketing manager of Finnish antivirus vendor F-Secure.
F-Secure warned users on Friday on its Web site that Doomboot.A was in the wild. Von Troyer estimates that around 30 million phones are potentially threatened. What makes Doomboot.A a serious threat to phones, according to Von Troyer, is the Commwarrior.B worm it contains.
