|Very likely yes... Although some factory restore routines occasionally allow an option that "allegedly" preserves personal files etc.|
In an ideal situation one would "regularly" copy (duplicate at least) all those important files to external storage; typically dvd, but an external hard drive too. And check those copies are ok when made, and occasionally thereafter.
What you can do is boot the system with a Linux disk, of which there several variants around. Two that come to mind are ubuntu (ubuntu.com) and puppy linux (http://puppylinux.org/main/Overview%20and%20Getting%20Started.htm).
Download the ISO and burn to a dvd; boot with that dvd.
You can then access the hard drive and copy your files to external storage as above.
Both of these linux variants are freebies; although a donation is often appreciated (but not compulsory).
Ubuntu may offer to install itself to the hard drive - which decline. Simply run the linux OS from the dvd. It will load itself into RAM only, and the hard drive is then merely a resource for the OS loaded in RAM. I think puppy linux does not offer to install itself... Both versions "will" run happily from the dvd.
When you have saved all your files (and checked the copies are ok on at least one other working system) then you can safely set about resolving your current problm - knowing your personal files etc. are safe off the hard drive.
This statement puzzles me though...
"admin user privileges are blocked by the MalwareBytes logo"
I don't follow or understand that... Malwarebytes doesn't run etc. usually until the system is booted and logged in?
And HP's response to buy their security package sounds like rip off answer; HP sounding like they see a chance make buck rather than simply help support...
