Favicon Hack

Hello Friends,

My site was hacked a while back and it has left a favicon. I cannot seem to find it. I believe it is well hidden, as I have spent a lot of time looking for it. Can anyone please tell me how I can deal with this anoying issue.

The URL is: https://i-brand.ca/
It is the black thing in the favicon spot I am trying to get rid of. I also put a shot, (in case it is helpful) of my root FTP folder in my Dropbox at: https://www.dropbox.com/s/5oqq6wyx1o3m5ur/ftp1.jpg

Many thanks in advance.
