acad.pat file reports as missing

First I did out it in a new profile. But the set current is grayed out. Also in explorer the file extension was in pdf and I right clicked and selected open with notepad and it converted the extension back to .pat.

Sorry but it's really starting to sound like your AutoCAD has been infected with a by Malicious Code.

To Recover From an Attack by Malicious Code

If your installation has already been impacted by a malicious application or routine that runs on startup, following these general steps:

Run your anti-virus checker. All leading anti-virus solutions identify and repair AutoCAD virus infections.
Start your AutoCAD-based product using the /safemode command line switch.
Find and remove all malicious code. This process is made more difficult if you had been running as an Administrator with User Account Control (UAC) turned off. As a result your AutoCAD install folder might be compromised as well.
Repair any affected files.
Set the SECURELOAD system variable to 1 or 2.
Set the TRUSTEDPATHS system variable to unique, read-only folders.
Remove the /safemode command line switch from the command line parameters.

Personally I'd never download a VLX, FAS or any compiled code. Many AutoCAD verticals like Civil 3D once relied heavily on VBA but none have had it since 2011 version since it was a primary source of Malicious Code. VBA has not been enabled by default since then and they've only allowed us to enable it since then because some firms may still have VBA code they rely on. I strongly advise not enabling it. Never set SECURELOAD (System Variable) to 0! Always follow those recommendations, they're not just for fixing you problem now.

Cadtag asked you if you have Windows Explorer set to display file extensions. Did you do that? Notepad will take the file and name it acad.pat.txt. If you don't have ext turned on, it will look like acad.pat.

Yes I do have it set to display
