What causes this error?

The error can sometimes be just a false alarm and just dismissing the error message and trying again can fix the problem. That said, other reasons for the error include the following.

  • Malware infection.
  • Issues with the source code of the program being installed. 
  • Improper update installation. 

Does the error mean you have a malware infection?

While the error may be caused by a legitimate program, it’s also often an infection indication. There’s no way to confirm this using the error message itself, so you’ll have to run a malware scan on your system to see if you’re infected. 

If you are, you should remove the infected files from your PC right away. Not doing so can cause data theft and can further breach the privacy of your computer including but not limited to keyboard/camera/mic access and remote takeovers.

Try again

As mentioned before, the error can sometimes just be a false alarm. If you were trying to install or run a program, just dismiss the error and try again.


Update macOS

Sometimes, the error can pop up because of a faulty macOS update. Check to see if you’re on the latest version available and if you’re not, update to see if that fixes your problem.
