warning message from host re ninja firewall file

Replies: 0

Hi,

I’m getting the following warning from my hosting provider:

THE FOLLOWING FILES MATCHES ONE OR MORE KNOWN MALWARE SIGNATURES.

Critical Directory Access Disabled – Jul 17 18:27:15 aluminium [‘/home/…/public_html/wp-content/nfwlog/firewall_2016-07.php’] – Known exploit = [Fingerprint Match] [PHP REQUEST Exploit [P0007]]

What does this mean?

thanks
