Windows Defender an antivirus program that is already installed with Windows 10, that is, you don't need to download any files or pay a subscription to keep the software running. It offers real-time protection against software threats, such as viruses and malware in e-mails or on Internet sites, preventing your computer from being infected. System scans are performed automatically and in the background.
Windows Defender also offers protection from threats that can come from files or data that are stored in the cloud. If something strange or potentially dangerous for the computer is detected, the program already activates its security system.
Windows Defender is able to detect, even in most cases, even threats, such as ransomware attacks. For this, the program is based on the behavior of the file: if it catches something different from the usual, the antivirus prevents its execution.

Recently, AV-TEST, an independent organization that evaluates security programs for Microsoft Windows operating systems, released a comparative study with different antiviruses available on the market. Windows Defender got a total score of 17 points, out of a total of 18.
The Microsoft program received 5.5 points for its protection power, 5.5 points for performance and 6 points for ease of use, which was considered a very good performance. It is the second time that Windows Defender has approached the leading paid security products on the market in an AV-TEST study.

Windows Defender cannot be installed on computers running Windows 7, due to system and program requirements. Windows Defender works on the latest versions of Windows 8 and 10.
Windows 7 PCs have installed Microsoft Security Essentials, which is the Microsoft antivirus that gave rise to Windows Defender. Both programs offer virtually the same security features, the main difference being that Windows Defender offers advanced protection against rootkits, which is not the case with Microsoft Security Essentials.

How to uninstall Windows Defender?
If you no longer want to use Windows Defender, it is recommended to just disable it, and do not uninstall the program. Action is possible, but you risk deleting folders or drivers that are part of the operating system. In addition, a Windows Update update in the future is very likely to restore Windows Defender and undo the action.
In addition, both disabling and uninstalling are indicated only if you install another type of antivirus on your computer immediately. Leaving the machine unprotected facilitates cyber attacks that can steal important personal data, such as passwords and credit card numbers.

Is it okay to install another antivirus on your PC?
Windows Defender does not prevent the installation of another antivirus in Windows 10. This is because, from the moment the program is installed, Windows Defender functions automatically disabled, since it has its firewall itself.
Action occurs precisely to avoid conflicts between the software, as an antivirus can detect the other antvirus as a threat, causing the computer to slow down or even crash. If you want to activate Windows Defender again, simply uninstall any other antivirus programs that are installed on your computer.
Incidentally, even if you choose to use another antivirus other than Windows Defender, you can still manually use the Microsoft program to scan your computer for suspicious files.
