Security and back up Protect your device You can protect your device from unauthorized usage or malicious software by using passwords and keeping your antivirus application up to date. Important: Your device can only support one antivirus application. Having more than one application with antivirus functionality could affect performance and operation or cause the device to stop functioning. Manage passwords You are prompted to create a Windows password when you log in for the first time. You can also create a password reset disk on a USB flash drive, so you can reset your password if you forget it. For instructions, select Start > Help and Support and enter Create a password reset disk in the search box. Keep your password and your password reset flash drive secret and in a safe place, separate from your device. Internet security Your device has an antivirus application pre-installed. To continue using the pre-installed antivirus application after the trial, you need to purchase the license from the internet security service provider.
