'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.

You did Not have to go buy a different printer. Almost none of the others who have posted on the now 6 pages of posts here had to do that.


---------

If you don't see it in Software Update, Apple now has it posted as a separate, manual download.


HP Driver update 5.1

--------

what you will need to do:

delete your old Printer Queue,

restart your Mac,

download new Drivers,

Add-A printer to get your full original functions back.


You should not have to fall back to generic postscript driver or AirPrint driver, but those remain as work-arounds.
