Hmmm I can't seem to install malwarebytes back on the 780. I do;t know what to click?
I clicked the box at the top of the page but just took me to a page to buy malwarebytes.

You know the routine by now.

AV products use Uninstall in Programs and Features control panel.
This is true.

But they always leave remnants behind. For this, you search
for "product name" and "cleaner" or "cleaner application".

Some of the cleaner tools, require you to do the Programs and Features
step first. This web page makes no specific mention of the Programs and Features
step, implying it is safe to use at any time.

Now, all of this being said, it's still up to the installer
logic of the thing you're trying to reinstall, as to how it
works.

The cleaner *should not* remove evidence of a Trial that has
expired. That would be silly.

Cleaners have been known to remove "paid license keys". If you
pay money for an AV, make sure you have a copy of the original
email that had the license key in it. Boxed software isn't
as common as it used to be, so I no longer have to tell you
to look in the box for a card with the License Key printed
on it. Electronic purchases require some care so that keys
are not inadvertently lost.

Chances are good, it won't take you to the free version.
I can't reproduce this here, unless I do an experiment,
wait 14 days for the materials to be ready, and then
repeat what you've done. And the end result might be
we're no better off as a result of doing the experiment.

Summary: Try the cleaner. With no guarantee it will change a thing.
