It may surprise you to know that the biggest risk to your mobile device is not hackers, but most likely you. You are far more likely to lose or forget a mobile device then have someone hack into it. The number one thing you should do to protect your devices is enable automatic locking of the screen, often called a screen lock. This means every time you want to use your device you first have to unlock the screen, such as with a strong passcode or your fingerprint. This helps ensure that no one can access your device if it is lost or stolen.
Malware is software--a computer program--used to perform malicious actions. In fact, the term malware is a combination of the words malicious and software. Cyber criminals install malware on your computers or devices to gain control over them or gain access to what they contain. Once installed, these attackers can use malware to spy on your online activities, steal your passwords and files, or use your system to attack others.
