HP Scanner 3

A lot of Mac users are nowadays reporting that they are getting a strange message on their Mac that appears in the form of a pop-up stating that “HP Scanner 3 will damage your computer”.

This alert seems to be connected with HP printer drivers which the built-in MacOS anti-malware App (Xprotect) seems to be detecting as malicious. Users with MacOS Catalina 10.15.7 seems to be getting the alarming pop-up warning the most.

Is it a smart idea that the “HP Scanner 3 will damage your computer” alert message be bypassed?

The “HP Scanner 3 will damage your computer” warning is not officially verified by Apple as a false positive. We, therefore, suggest that you do not underestimate the warning easily. It is quite possible that your MacOS may have discovered something questionable or malicious, so such warnings should always be handled carefully.

How do I bypass the Mac notification anyway?

One of the ways is to right- click  the app and select Open.

You will get a “HP Scanner 3” alert, but you can still open this software.

Additional options for bypassing the warning:

1. Locate HP Scanner 3 through the Finder.
2. Control-Click on the app.
3. Through the shortcut menu select Open. From then on the program is whitelisted, and you can open it without seeing the “macOS cannot verify that this app is free from malware” alert.
4. Another way for whitelisting the app is to navigate to “Security&Privacy” Preferences and select Open Anyway.

Remember that this button would be available only for an hour after you have tried to open a blocked application. To navigate to it, follow the directory described below:

Apple Menu>>> System Preferences>>>Security&Privacy>>>General.

Is my Mac at risk?

This HP framework could be safe and malware-free. However, it may contribute to system exploits if not addressed carefully.  Thus, we recommend to search the computer with a trusted anti-malware tool that checks and removes system dangers or other files that could cause problems in future. ComboCleaner is a great tool for doing so.
