Windows Defender and Security: The article notes that Windows PCs have built-in protection through Windows Security, a basic antivirus and firewall suite included with the operating system. However, it suggests using additional antivirus software for enhanced security.
Need for Antivirus: It emphasizes that any Windows desktop or laptop connected to the internet requires antivirus protection. The article concludes by mentioning the importance of antivirus not only for computers but also for other connected devices like phones, tablets, smart TVs, and IoT devices.
Overall, the article provides insights into the significance of antivirus software in safeguarding digital information and devices in an increasingly digital world.
