I am working on trying to solve this issue with this Adhitz warning popping up. I had an account with them a long time ago and I decided to remove their ads from my blog a while back. Now it is telling us to remove it, but it is already removed.
I contacted them and awaiting a response to see why it is happening and waiting for them to fix this. My account was inactive for quite some time so I can't even login to deal with it. I recommend you do not deal with Adhitz on your site. I googled to see how to deal with this and well others have had the same issue.
I assure you tho that if it was suspended, it was due to inactivity and my removal from the blog. I am unable to find any of their code in my html so please I recommend not using them at all. I am not at all amused with them at this moment.
