How does Windows Defender work?

By providing excellent automatic protection against malware with minimal impact on system performance, and a surprising number of additional features, Microsoft’s Windows Defender has almost caught up with the best free antivirus programs.

For many users, scheduling scans is too time-consuming, and in addition to Edge Or web browsers other than Internet Explorer have no security. In addition, there is no independent password manager or file shredder available.

With Windows Defender, what you see is what you get. The amplification of protection or the addition of functions cannot be obtained as an upgrade. Considering the complete Windows security equipment, it includes firewalls, drive-level encryption, and even game modes.

On the other hand, it still lacks the functions of third-party antivirus manufacturers as incentives, such as file shredders and access to virtual private networks (VPNs).

In addition, Windows Defender provides world-class malware protection, which provides a convincing reason not to replace it with a third-party antivirus product.

Its only disadvantage is that some of its defense activities, such as scheduled scans, are difficult to set up, and some linked Windows defenses are limited to Microsoft’s own browser. These are minor shortcomings.

Is Windows Defender good enough?

In terms of network security capabilities, Windows Defender has made great strides since its inception. It used to be very bad, but Microsoft recently improved Defender to make it a pretty good free antivirus software.turn-on-defender

Because Defender now integrates sandboxing and cloud-based malware detection, it provides better overall security while detecting threats faster than ever before.

Detecting malware files, preventing exploits and network-based attacks, and flagging phishing websites are all Microsoft Defender can do things.

In addition, it has simple PC performance and health monitoring, as well as parental controls including content filtering, usage restrictions, and location tracking.

Since Windows Defender now integrates all these beneficial features, users will question whether they can rely on it alone to protect their computers, or whether they need to use a third-party antivirus program in addition to it.

the fact is,Microsoft Defender is now easier than ever to compete with third-party Internet security suites. However, it is still not satisfactory.

Of course, Defender is free to download, but there are reasons why Internet security suites are so expensive, the most important of which is that Microsoft does not engage in network security business.
