What caused this error?

Now, after discussing the solution to this problem, let’s just try to figure out what caused this particular error.

For starters, as we all know Microsoft Defender is a built-in antivirus system shipped with every Windows product.

Now, it is no rocket science, that every software, no matter the device, needs regular updates to fix itself from any previous bugs and security glitches. 

So, the Microsoft team did the same and pushed an update to its default antivirus system aka Microsoft Defender.

By doing this they also updated the list of apps that should be considered a threat to the system and immediately hibernated to stop further damage. 

However, by chance Microsoft team included almost every Chromium and Electron-based app on the list,

Which included Microsoft Edge, Chrome, Chromium, Firefox, WhatsApp, Discord, and Spotify, resulting in a “Behavior:Win32/Hive.ZY” warning to pop up on the screen,

Whenever a user tried to open these “Safe and Trusted” apps.

Here is the full warning message that pops up on the screen.

Threat blocked

Detected: Behavior:Win32/Hive.ZY

Status: Removed A threat or app was removed from this device 

Details: The program is dangerous and executes commands from an attacker 

Affected items: behavior :

pid:25924:74439979291537

Not just that, many users communicated this concern through Microsoft’s official forum and various social media platforms like Twitter and Reddit.

A Reddit user named AHeroicLlama posted an AMA asking other users about the problem, while a user named Georgeescot answered it.

Here is a screenshot for your reference.

Although after many users started reporting this problem, the Microsoft team got alert, and within a few hours they rolled out a new Defender update, which immediately fixed this problem.

But in the end, this mistake for sure tarnished the company’s reputation and goodwill.

Is it safe to use Microsoft Defender rather than third-party antivirus software?

Antivirus software plays a vital part in protecting our data whether it be online or offline, and therefore cyber security experts always recommend each and every user to install a good and reputed antivirus software on their devices. 

However, with Microsoft shipping its free antivirus system with every Windows product, users don’t feel like purchasing additional third-party antivirus software. 

Now, the question is, do you really need additional security software apart from Microsoft Defender?

The answer is, Yes.

No doubt, Microsoft Defender does the job very well and is a free premium product by Microsoft.

Still, other premium antivirus software like Quick Heal, Avast, Norton, McAfee, and Kaspersky provide additional security features to their users. 

Not just that, with viruses taking a step forward and getting stronger with every new update, it has become essential for Antivirus software to be up to date.

Thus, there is no harm in keeping two antivirus softwares on your PC at the same time, rather than waiting for such uninvited errors to pop up. 

Therefore, install another antivirus software on your PC or Laptop to be on the safer side.

Final Remarks on How to fix “Behavior:Win32/Hive.ZY” on Windows?

After this discussion, it is clear that the “Behavior:Win32/Hive.ZY” is just a false positive that was caused due to some error in the listing of Microsoft Defender’s new update.

However, this issue can be easily fixed by a quick update or by turning off the virus and threat protection notifications by accessing Microsoft Defender’s “Settings” menu.
