Update existing Zen Cart to Most Recent

I would like someone to update my current Zen Cart webstore to the latest version. Pretty simple task, I am sure. In addition, the webstore has seen an abnormal counter history on the pages that are not legitimate. I don't know if there's been a hack and someone has placed a file that is being accessed and sucking up my bandwidth or what it might be. I'd like to have someone eliminate whatever robot is running and running up the web traffic on the server/webstore. Average hits used to be from 150 - 500 a day. A busy day would be 150 - 1000. I'm have been seeing the counter history report 20,000 - 30,000 a day which should not be happening and is causing problems with a script that I am running to access an outside webstore for product availability. When submitting a response to this job, please make reference to what I am asking you to fix and how you will fix it (doesn't need to be detailed, I just want to know that you've actually read the description). Thanks
