Before we start configuring the security measures, let's look at the tools that Windows 8 provides to defend us against these threats. Windows Firewall Windows 8 comes by default with its Firewall activated because when your computer connects to the Internet another person is able to access your computer and infect it with a virus or cause problems in it. Windows Firewall prevents intruders from accessing your computer while you are online. 
Windows Defender Spyware are programs that are installed on your computer without your consent or without your knowledge. These programs collect information from your computer, steal passwords, display advertising and take control of your browser. To prevent these programs from being installed on your computer, Windows 8 includes Windows Defender . 
Anti-Phishing Phishing refers to emails or websites that seem to come from legitimate businesses and organizations but now come from professionals in the art of cheating on the web. The purpose of these messages or sites is to deceive the person so that they disclose personal and private information, such as: passwords and credit card numbers. Internet Explorer and Windows mail come with anti-phising to prevent this from happening. Junk mail filter Spam refers to mail advertising ranging from baldness cure to cheaper printer cartridges. Most of these emails contain fraudulent information or some lead to adult content sites, however these emails can take us to sites that install some Spyware on our computer. That is why Windows Mail has implemented a filter to protect us from these messages.
