Security
Update your PC automatically Windows Update installs important updates as they become available. Windows 8 will turn on automatic updating as part of the initial setup process. Keep in mind, Windows Update won't add any applications to your computer without asking for your permission.
Antivirus protection In Windows 8, Windows Defender replaces Microsoft Security Essentials. Windows Defender runs in the background and notifies you when you need to take specific action. However, you can use it anytime to scan for malware if your computer isn t working properly or you clicked a suspicious link online or in an email message.
Avoid scams with new phishing filter Windows SmartScreen is a new safety feature that can help protect you from phishing scams and new malware that your anti-malware software hasn't detected yet. It warns you if it doesn't recognize a website or app. You can also change Windows SmartScreen settings for how it handles unrecognized apps.
