In Windows 10, Windows Defender helps protect your PC against malware like viruses, spyware, and other malicious software for free. The software now provides both real-time protection built into the system, and can also perform full hard drive scans. Here's how to turn Windows Defender on and off.

The solution is so effective that Windows Defender is increasingly recommended by security experts. In addition, the advantage of this solution developed by Microsoft, is that it does not modify the normal functioning of the applications of the system. A guarantee of stability.
The other advantage is that this completely free solution consumes little system resources compared to other antivirus solutions. No need toactivate windows defender on a newly installed system or on a new Windows computer since this is the default security application. However, some prefer to deactivate it in favor of a third-party antivirus solution. The process is reversible at any time.
