Is windows defender enough ?

[dgray8851]

Using Window defender for a very long time. I had a pretty good experience with it. But often I had to disable it to download several files I think overall window defender is good if we update it from time to time

Let me add something worthy. Window defender just saved my computer from being hacked as a trojan was running in the background which not only spams your data but also steal your information without letting you. It popped a notification in a template instantly when i was going to run that spammy software.

Windows Defender is a good antivirus program that is included with Windows 10 for free. It can provide effective protection against many types of malware, including viruses, worms, and ransomware.

However, it is always a good idea to use multiple layers of protection to ensure the security of your device and your personal information. [*** Advertising deleted by Staff.

Windows Defender, which is the built-in antivirus software in Windows operating systems, can provide basic protection against common threats and malware. However, it may not be enough to provide comprehensive protection against advanced and sophisticated threats, such as zero-day exploits, ransomware, and persistent malware.

It's also worth noting that Windows Defender only provides protection for Windows-based devices, so if you use other devices and platforms, you'll need additional protection for those devices.

Therefore, it is recommended to complement Windows Defender with additional security measures, such as using strong passwords, keeping your operating system and software up to date, avoiding suspicious websites and emails, and using a reputable third-party antivirus software. This can provide an additional layer of protection and help ensure that your device and data are protected against a wide range of threats.

Windows Defender won't run in the presence of most reputable antivirus products, since once they register themselves as an AV provider Defender will automatically turn itself off excatly as it's designed to do..

Microsoft has never ever supported the simultaneous operation of 2 true AV applications at the same time, since the design of the core Windows API calls that support their operation is only capable of managing one security app.

Though there are other security apps like Malwarebytes Anti-Malware (MBAM) that do claim to support simultaneous operation with Defender, that's not supported by Microsoft itself, so it's up to the Malwarebytes to ensure this continues to work and we've seen a few issues with this in recent times as well as the past. So generally those here don't recommend this and instead suggest using MBAM as on on demand scanner.

Windows Defender is a good basic antivirus, but a paid option like Kaspersky can provide extra protection.

Windows defender is pretty darn adequate.
There are many features out of the box that aren't enabled, and aren't available on home editions, like ASLR, Exploit Protections, Credential Guard, Protected Folders, Etc. Look into those and enable them. Annoying but 100% worth it.
Also all AV on windows is required to use the same APIs and syscalls as defender. So effectively all av is no better than defender.
Plus, to some extent all AV contributes to a level of security theater but that is a conversation for another day.
I'd be glad to point you to some docs, but I'm not gonna include any external links here.
You can find everything you need to know about defender on the microsoft docs page.
