Does my BlackBerry smartphone need anti-virus software?
Preventing malicious programs such as viruses, trojans, worms and spyware (collectively referred to as “malware”) consists of two parts: detection and containment. Detection is the process of determining whether a program is malicious (i.e., malware). Effectively detecting malware is very difficult. It requires a large, frequently updated, local database or a constant connection to an online database. While desktop computers can satisfy these requirements, mobile devices cannot. Mobile devices do not have enough storage space to hold a malware database and a constant connection to the Internet cannot be guaranteed. Containment is the process of preventing a malicious program from causing damage once it has appeared. Containment is relatively easy. It simply requires controlling access to the device software and other applications on the device. The BlackBerry solution focuses on containing malicious programs. The BlackBerry software and all of the core applications are digitally signed
