 * Every time I enable W3TC, malware links get injected into my cache files and 
   my site gets black-listed. This only happens when this plug-in is enabled. I’ve
   removed it, all cached files and then reinstalled it. The problem still happens.
   My server host has run multiple scans on the server and can find no malware when
   W3TC is disabled. Shortly after it’s reenabled, they run another scan and the
   malware links are throughout the cache files.
 * Any idea how in the heck this happens and what I can do to make it stop? I’m 
   running the latest version of WP and W3TC and have run WordFence scans against
   the installed files.

 * You might have some malware that is dependent on W3TC to run. If you can send
   us your site, we can scan it for you to see if we can identify what is going 
   on.
 * You can also try to scan it here: [http://sitecheck.sucuri.net](http://sitecheck.sucuri.net)
   to see if it is a known injection.

 * It was listed on that site prior to me turning off W3TC.

 * If you engage the Sucuri Research team at [labs@sucuri.net](https://wordpress.org/support/topic/malware-27/labs@sucuri.net?output_format=md)
   they’d love to learn more about the case and figure out the specifics of your
   environment and what you’re seeing. It might make for a very interesting write
   up.
 * Thanks
