Database is generating unwanted and unexpected files
Using Front Page, I have created a website called Pivotal Kids. The home page is http://www.pivotalkids.com . Recently, in analytics, I have discovered new files that I didn't upload and that are not visible to me in the database. My hosting support says they were generated by the database.
Here are some examples:
I accepted paid advertising for the site recently that seemed strange, but not anything bad or illegal.
Can you suggest how these files are being created and more importantly, how to get rid of them and stop them being produced? Please and thank you!
