<p><strong>Warning: <em>Checksum Verifier</em> has reached end of life. Its functionality is available in AntiVirus 1.4.0, use this plugin instead.</strong></p>
<p><em>Checksum Verifier</em> calculates MD5 checksums for all existing WordPress core files and checks them against official checksums. It thus will detect and react upon any unrecognized modifications made on your WordPress core system (for example <a href="http://blog.sucuri.net/2014/12/soaksoak-malware-compromises-100000-wordpress-websites.html" rel="nofollow ugc">SoakSoak malware</a>).</p>
<p><em>Checksum Verifier</em> runs a daily check on MD5 checksums. In case an unexpected result is detected in core, the plugin will send an e-mail with a list of affected files to site administrators (or super-admins in WordPress multisite). The first check-up will be executed during plugin activation. Regular core updates won’t cause any alarm, of course. Only in case core files have been compromised and your site might have been hacked, the plugin will notify you.</p>
<p><em>Checksum Verifier</em> works as a “silent” background process and will only bother you in case of unexpected file modifications that could potentially threaten your core install.</p>
<p>Better security with WordPress.</p>
