I don't believe there's anything wrong with these USU5 files but need your opinion anyway. They are cited as possibly hacked when I run the Sitemonitor:
 
includes/modules/ultimate_seo_urls5/classes/Usu_Cache_Database.php
includes/modules/ultimate_seo_urls5/classes/Usu_Cache_Memcached.php
 
In case I must have missed something, this is one of the files:
