Amazon's Kindle store has no security products for its dedicated e-readers, but there are several available for the Kindle Fire and Fire HD. These include apps from major industry names such as Norton and Avast, well-known for their anti-virus and anti-malware products on other platforms. Features vary between products, but typically include protection against the major families of viruses, trojans and other forms of malware. They also offer additional features targeted to mobile users, such as locating missing devices, photographing illicit users and erasing stored data. These help protect your Amazon accounts as well as the physical devices.
