Hi there,
Yes I can confirm that the “scan image files as if they were executable” was enabled.
My Wordefence has just upgraded itself to the latest version and I am about to see if this version will now detect anything – I’ll let you know.
I have gone through the cleaning guide previously but Wordfence is not detecting the javascript.
I’ll send the code on to the email and let you know if the scan comes back with anything this time
