This is the first time I hear about this. How do you know the malware comes from akamaihd.net? What happened exactly? What the files of the plugin modified?
By the way akamaihd is a CDN service used by Facebook. Are you really sure this is a malware problem? Maybe it’s a bug or an issue somewhere and not an attack at all 😉 Attacks usually send you to bad websites or add a lot of backlinks.
I see.
I saw the “akamaihd.net” in the lower portion of the browser window and did not recognize it, assumed it was malware. My site doesn’t have any connection to Facebook so not sure why that would happen.
Basically, when the plugin was active, the page would load, then, at the very end of the load, I saw the message “read cdncache-a.akamaihd.net” at the bottom of the page and the page would then redirect to “/null” resulting in a 404.
FYI, I just re-activated your plugin (v 4.4.4) and tested again, same thing.
With your plugin deactivated, no error.

Good luck.
Ok, this is definitely not a malware then 🙂 No idea why this URL is being accessed but as you know, the plugin and associated scripts are looking for the @2x images. The plugin itself has not link to “akamaihd.net” anywhere however, so that link comes from another image or plugin. Then WP Retina 2x tries to get the Retina for it. I looked at your websites and your theme a lot of scripts (and there are also a few links to Facebook) so it might really come from any of them.
