Windows 8 has built-in Anti-Virus software

One of the best things I like about Windows 8  is that it has built in anti-virus protection. There’s no need to spend extra money on an anti-virus software.

Windows 8 has built in anti-virusWindows Defender and Windows SmartScreen are built into Windows 8 and Windows RT and help guard your PC against viruses, spyware, and other malicious software in real time. Windows Defender uses green, yellow, and red color codes to show your PC’s security status.

When Windows Defender detects a suspicious app or other unfamiliar software, it checks it against a Microsoft database to make sure it isn’t known to do anything potentially harmful. Windows Defender keeps track of known malware automatically, but you can also get updated lists whenever you want.

Windows Defender runs in the background, and only notifies you if there are specific actions to take—but you can also run your own scan whenever you want. If your PC isn’t working properly, or you got an email from someone you know that just doesn’t seem right, use Windows Defender to check for malware you might have downloaded inadvertently.

Note: In Windows 8 and Windows RT, Windows Defender provides the same level of protection against malware as Microsoft Security Essentials. You can’t use Microsoft Security Essentials with Windows 8 or Windows RT, but you don’t need to—Windows Defender is already included and ready to go.

Windows SmartScreen is a new safety feature in Windows 8 and Windows RT that can help protect you from new malware that antimalware software hasn’t detected yet. When you download and run an app downloaded from the Internet, SmartScreen uses information about the app’s reputation to warn you if the app isn’t well-known and might be malicious.

SmartScreen Filter in Internet Explorer helps protect users from phishing and malware attacks by warning you if a website or download location has been reported as unsafe.

Is Windows 8 ready to put anti-virus companies out of business?
