To fix the problem temporarily until you get rid of the malware ask your hosting provider to site lock your website. This will make the files and directory read-only

Probably your webhost locked the updates? Is it a shared hosting?

PHPMyadmin is just Database (mysql/mariadb) client. It sees what it gets from mysql. Probably your Database is corrupt or there is problem with mysql configuration. You should attempt a fresh install of WP, if you see same errors in the fresh/vanilla install of WP then probably your mysql installation is corrupt and you need to reinstall it.

Thanks for the response.
