'hpPostProcessing.bundle' malware?

Today I was working on my MacBook Pro and I wanted to print a document on an HP printer. When I pressed the 'print' button, Gatekeeper told me the following proces/application is malware and does harm to my Mac: 'hpPostProcessing.bundle'.


Normally I never have this issue when I want to print anything on the printer that I used today. Could anyone tell me if I need to assume that this process/application is really malware, or that I can assume that it is a 'false positive'?


Thanks in advance.

User ewayte found the main reason. It's part of the link he supplied:


From sources familiar with the matter that HP Inc asked Apple to revoke its printer driver code-signing certificates. It appears this request backfired as it left users unable to print. A HP Inc spokesperson told us on Friday night:


We unintentionally revoked credentials on some older versions of Mac drivers. This caused a temporary disruption for those customers and we are working with Apple to restore the drivers. In the meantime, we recommend users experiencing this problem to uninstall the HP driver and use the native AirPrint driver to print to their printer.
