What is Windows® Defender?

Windows® Defender is a free program that helps you stay productive by protecting your Windows® enabled computer against pop-ups, slow performance, and security threats caused by adware, malware, spyware and other unwanted malicious software. Windows® Defender is a Real-Time Protection and monitoring system that recommends actions against spyware when it's detected and minimizes interruptions. This program works on Windows® XP & Windows® Vista. It is included and enabled by default in Windows Vista® and Windows® 7, and is available as a free download for Windows® XP and Windows Server® 2003.

About Firewalls

Firewalls can either be a piece of software or hardware installed on your computer system. The Firewall’s job is to filter out malicious software like viruses, worms, Trojans and hackers who try to invade the privacy of your computer system over the Internet by identifying potentially harmful data connection being made to and from your computer. Windows® comes with an inbuilt firewall that is much like the firewall products in the market. The Windows® firewall is good enough you are working behind a home router.

Windows® Defender and Firewalls

Windows® Defender protects only against adware, malware and spyware. It is not an antivirus program and will not protect your PC against virus infections. The same goes for the firewall (either Windows® or third party). If you're running your Internet connection through a router then it will most likely have a firewall too. Both of these software are highly specialized in their form and functions. You will need to supplement your security with a good antivirus software on your PC. Also, if you need added security like e-mail protection, anti-spam, file encryption for sensitive data or file shredding services; you will have to integrate a security suite or a slew of other products as well. Moreover, the Windows® Defender is actually comparable to the free products on the market.
