So what is Windows Defender?
I bet you all know Microsoft Security Essentials (MSE), an antivirus software (AV) product that provides protection against different types of malicious software such as computer viruses, spyware, rootkits and Trojan horses. 

In Windows 10, we have Windows Defender, whose functionalities are similar with MSE and I think it’s even stronger than MSE. It is a free Anti-virus software if your Windows 10 is genuine. 

In my opinion, I think you don’t need to install any other antivirus software. Windows 10 will be fine with Windows Defender.

In this article, we will guide you steps to protect your Windows 10 PC with Windows Defender.

Step 1: Open Windows Defender
1. In the search bar (Cortana box), type Windows Defender.
2. Pick Windows Defender in the results. You’ll be able to check your computer and your level of virus protection.
