How to remove this hack?

[apokphp]

I believe this is from https://vborg.vbsupport.ru/showthread.php?t=231666. But the author is no longer supporting the mod. I uninstalled this mod quite a while ago...but I'm still getting sql errors:

Database error in vBulletin 4.0.7:

Invalid SQL:

SELECT userid, usergroupid, displaygroupid, username, posts, post_thanks_thanked_times
FROM user AS user
WHERE post_thanks_thanked_times > '0'
ORDER BY post_thanks_thanked_times DESC
LIMIT 0, 15;

MySQL Error : Unknown column 'post_thanks_thanked_times' in 'field list'
