this file:
./wp-content/themes/weaver-xtreme/admin/admin-core/admin-page-posts-meta-boxes.php
showed up as a unix file, but line breaks were ctrl-M. we had this issue before with the last upgrade. it a minor issue for sure, but one of my homegrown virus scanners is looking for the longest line in a script, and then sorting by which script contains the longest line.
it’s been my experience that very long lines in php scripts are suspect for being comprimised.
