“HPDeviceMonitoring.framework” will damage your computer.

HP has published a Fix: https://support.hp.com/ca-en/document/c06960563

Just went to this HP support page. It will walk you through uninstalling the drivers and then re-installing. Worked for me https://support.hp.com/us-en/document/c06960563

hi, 1 plist file in LaunchAgents folder that was causing the popup for me, when I looked at the plist file properties, it was created on 22nd oct, deleted plist file and restarted Mac, no popup. thanks again for all your help. if this didn't work, would have taken drastic steps, a full factory reset.

do you know if It was malware? strange how everyone got it at the same time with different creation dates etc. I'm off to complain to malwarebytes, I'm paying £29.99 a year for malwarebytes for Mac(premium) with latest updates installed, ran a full system scan 5 times and got all clear for all of them

thanks again

I could not use Finder to locate "Library/LaunchDemons" or "~Library/LaunchAgents" I had to go to the "Library" folder, where I found "LaunchDaemons" There was no more recent file than Oct. 13 and it was "com.microsoft.autoupdate.helper.plist"

In "Library/LaunchAgents" I found 2 HP files (plist) which were dated Oct. 22 and I deleted those.

I need to restart my laptop to see if that did anything. Meanwhile, I hope Apple will also do something!

Aqua_RT, that might work, though for me it didn’t. I used the ➖ in the Printers & Scanners panel of System Preferences, but no app I have magically restored the instance. Then manually using ➕ to put it back I still wasn’t able to print. Only doing the complete Uninstaller method from HP got me cleaned up enough to put things back.

The post by @TCMeyers on page 4, going to 123.hp.com, using HP Easy Start to uninstall and reinstall, worked for me! The next morning I did see the update from Apple for HP Printer Software Update 5.1 as well, but mine was working prior to that.

I was having this problem too. Here is what worked for me:

About 6 posts down there is a reply from IronBadger with two sets of instructions (shorter first, longer second)

The shorter set of directions did not fix the problem for me, but the longer one did (using HPEasyStart to uninstall HP software and then re-install it). I am no longer getting the popup, and I can print as needed

I did that and it removed the problem just fine. However I found when I tried to reinstall the HP driver software, a new version of this problem popped up. Not the same framework, but a slightly different one. The net result was the install failed and I had the Malware message again popping up on me. This time I hit the show in finder button message and deleted the whole framework. That shut down the message from popping up again. The issue of course is what to do about my printer and scanner. I hope HP puts out a fix for this soon.

Following some suggestions here I:

1) run the uninstall procedure for HP software as advised by Lindenbaum (N.B. trying to re-install the printer using the same method (HP Easy Install) does not work because the Photosmart c4500 series is not supported anymore);

3) removed the printers from the Printer list in the System Preference pane;

4) removed (actually compressed and stored for backup) the hp folder in Library/Framework/

5) rebooted;

6) re-installed the printer from the System Preference pane; this forced my Mac to download the drivers and software from Apple.

Now the warnings have disappeared and I can print. However if I try to use the scanner I still get a warning message and I cannot proceed. So it is a bug that has to be fixed by HP/Apple.

I've used the same method ie uninstall using Easy Start(don't go past the first page) then getting the Mac to install the printer - only issue I've got now is that I can't print wirelessly - I haven't tried scanning though but after the frustration of the last few days I count that as a victory. Come on HP get a proper fix!!

I did a search for "HPDeviceMonitoring.framework". This folder was in Mackintosh - Library - Printers - HP. I moved the folder to the trash and then clicked OK on the pop up which closed OK. I haven't emptied the folder from the trash but have checked that I am still able to print.

Apparently Apple revoked the certificate for the driver for HP printers. So now the wonderful security detects it as malware. Here is a link explaining what has happened and how to fix it. mac-users-unable-to-print-after-apple-revoked-hp-certificate

I just find it interesting that if you remove the hp folder inside the Printers folder inside the drive's Library folder, then install this newly downloaded HP Printer file, you do not suffer from the issue that started this discussion in the first place, yet if you remove the offending folder listed in the popup warning, the Software Update says you have an update of this HP installation, and if you install the HP printer system *that* way, the popup comes up again.

I downloaded the installer from HP site (5.1) and after install and restart everything was good and up to date. I believe the Apple download is corrupt.

Yes, but does the printer work? it's hard to imagine the printer doesn't need at least some of those files?

I went to HP website, downloaded the latest update 5.1, and installed and once restarted my Mac told me I didn't need an update and the printers worked fine.

So the problem is that the HP on the Mac website is corrupted and once the update happens it starts giving warnings but once the actual HP update is installed from HP it stops. So HP probably uploads those to the Apple site but this one got corrupted - just a guess.
