HP will damage your computer…

December 29, 2020 by Gregg Montgomery

Have you seen a message like this on your computer?

 

 

If you are a Mac user, and an HP printer owner, you might see a message like this eventually. First and foremost, the good news: No, this actually isn’t malware, and it won’t damage your computer. The bad news: You still have a problem that needs a solution. Recently I’ve been getting a lot of calls about messages like the two displayed above, but there are many variants of this scary message, and they all have in common the notion that an HP (Hewlett Packard) device will damage my computer. All of these messages also happened to have appeared on Apple Mac computers. I think it’s possible that these messages could affect Windows computers as well, but I don’t work with Windows very much, so I just don’t know. In case the pictures above are hard to read, here’s a couple examples of this message;

HPDeviceMonitoring.framework will damage your computer

HP Scanner 3 will damage your computer

HPDM.framework will damage your computer

So is this some kind of new malware? No, it does not appear to be malware, even though the computer appears to think so. My initial research when this issue first arose in the Fall of 2020 was that this message was related to some kind of expired certificate or support file for HP printer/scanner units. Apparently, when these support files expire, the computer flags them as malware and presents a pop-up message like the examples above. I’d like to share how I resolved this issue for most of my clients, but I should warn you that I have encountered two very different outcomes. At best, this can be resolved by deleting the file in question, and then reinstalling the print drivers, a task which many could do on their own, and instructions are below. At worst, you may need to replace your printer.

Here’s how I resolved this issue for most of my clients. Take another quick look at the images above that display the error message, as I’ll be referring to them in my instructions.  Click the button on the error message that says Show in Finder. This will open a window and display a system folder where the expired support file resides. Delete the file in question, but don’t touch anything else in this folder. Generally speaking, deleting files you don’t recognize in your system folder can, actually, damage your computer, so it’s safer to just let it alone unless you know it’s creating a problem, as it is in this scenario. Once you’ve deleted the file, close the window. This solves the first problem, but it creates a new one… you can’t print anything.

Now we need to reinstall the printer driver for your HP printer. Open the System Preferences app, which may appear on the Dock at the bottom of your screen as a box of silver gears. In the window that appears, click Printers & Scanners. Any printer drivers you’ve installed appear in a list on the left side of this window. You may only see one printer listed, and that makes sense if you only ever print to a single printer in your own home. Select your HP printer in that list, and then click the – symbol at the bottom of that list, and then click Delete Printer to confirm. The printer will disappear from the list.

Now let’s install a new printer driver. Make sure your HP printer is turned on, and connected either to WiFi, or via USB cable to your computer if that’s how you usually print. Now click + at the bottom of the printer list, and another window appears, which is the computer searching for a connected printer. If the computer ‘sees’ a printer, it will display it in this window in a list, and again, there could be only one device that appears. By the way, if it says USB multifunction next to your printer brand and model, that means the computer sees that the printer is connected via cable. If it says Bonjour, that means the computer sees the printer on the wireless network. Select your printer, and then click Add at bottom right. Wait a few seconds, and that should be it. The second window will close automatically, and your printer should now be displayed in the printer list. You can now close this window too.

That’s it. Hopefully, you should be able to print or scan again at this point, and the computer should be happy and not bother you anymore with the same error message. Happy printing :0)

If these instructions seem like too much, or you have difficulty, please contact me and I’ll be happy to help. There’s a big Contact button on my website at the top you can use to reach me if you don’t already have my contact information. Thanks.

Tip of the Month

Closing Safari Windows on iPhone/iPad

Don’t forget to close Safari windows to keep your mobile device running fast and to minimize clutter. While browsing the Web in Safari, tapping on links here and there will often generate a new Safari window, leaving the previous window open, but tucked behind the new window, out of view.

Safari can stack up dozens of these open windows, often without much awareness of the user. Having too many windows open can slow down your device, as Safari tries to keep all those Web pages loaded. This can also create visual clutter, leaving users wondering why they can’t open a new Safari window, or how all those open windows got there in the first place.

Closing all your Safari windows can be done by locating the Open Windows icon, which looks like two overlapping squares. Long press the Open Windows icon, and then tap Close All # Tabs. Tabs is just another name for a browser window. And a ‘Long press’ means you need to delay your touch on the icon for just a second or two.

I recommend doing this each and every time you finish browsing the Web on your device. This will keep your device less cluttered, and running a little faster. Don’t forget you can always re-open any Web page that was closed due to that process, by finding it in your History. To find History, tap the Open book icon, and then tap the Clock icon. This will display your History – a list of all the Web pages you were viewing recently. Tap one from the list to re-open that Web page.
