Malicious Content in File

Hi Andy,

Just thought it worth dropping you a line to say that Wordfence (Premium version) has marked up a file as containing malicious code on my site.

Filename: wp-content/uploads/church-admin-cache/debug_log.php
File Type: Not a core, theme, or plugin file from wordpress.org.
Details: This file appears to be installed or modified by a hacker to perform malicious activity. If you know about this file you can choose to ignore it to exclude it from future scans. The matched text in this file is: viagra online

The issue type is: Spam:HTML/spamtags.3942
Description: A spam link known as spamtags

Is this a file I can simply delete? being under /church-admin-cache/ ??

Inspecting the file returns several places where ‘viagra’ has been inserted. (see below)

Is this simply the remnants of someone trying to register on the site? I’ve not received any notification of such an attempt to register.

Many thanks,
Kind Regards,
Rich.
