Question for Arlex Wong

Hi Arlex, you recently helped me with an issue of the header module showing on all pages for easydiscuss. I gave you backend access and you fixed it. Thank you!! I noticed yesterday that there is an unknown extension that I did not install and was wondering if this is something you installed in order to help me? you are the only one who has had backend access, so I am starting by asking you. Otherwise, I'm at a loss as to how this extension got there and will delete it. Thanks! Image attached.
