Malware

Malware is software that can harm the device. Malware or harmful applications can include viruses, worms, spyware, and other unwanted programs. While the device does employ security measures to resist such efforts, Sony Mobile does not warrant or represent that the device will be impervious to the introduction of malware. You can, however, reduce the risk of malware attacks by using care when downloading content or accepting applications, by refraining from opening or responding to messages from unknown sources, by using trustworthy services to access the Internet, and by only downloading content to the mobile device from known, reliable sources.
