Hey James,
You were correct. That did not solve my problem. After I did change the FTP Quota, I did not see the popup any more. After two hours it showed up again. Here is what I have done, so far.
Scan your local environment. - Malwarebytes
Scan your website.- I used a couple of plugins-one brought of my source, I tried reviewing it but I am not skilled enough to whitelist
Check with your hosting provider. – Not really a lot of help, which was a surprise because Gator is usually very helpful
Improve your Access Controls – deleted all users except my ID and I changed the password on it
Updated my WordPress Theme- not a new version just a reinstall of the latest
