Thanks,
I rolled back my site database to before the hack which got my reviews back then Ive updated to the latest version of the plugin.
I believe I was running a slightly outdated version.
Looks to be some form of exploit which allows injection of code into the custom CSS rules.
Yep, that was the code we had.
Looks like the malware redirect code was injected through a stylesheet included in the plugin in the header of the site.
Mine was the same, had to remove the plugin and downgrade the version – now my review scores are gone – do you know how to get them back ?
