Happened to one of my sites too but it was just fixed.
Another symptom,I cannot long into cpanel for any of my sites. Not sure if this is TCH related or hack related. I'll worry about it in a couple of hours.
Full restore works pretty well. However it does not remove additional files that were added. It will overwrite existing files which fixes a majority of problems. For example the front page extension folders didn't originally have index.php files but were newly creates. The restore didn't remove those but the script from TCH may have removed those.
