What is fileusr.com?

I can’t recreate the issue. Our client is getting malicious content warnings using Forcepoint’s SmartFilter software. It’s telling them that the content in the html widgets is being hosted at http://www.ourwebsite-com.filesusr.com instead of just http://www.ourwebsite.com as it should be. In this case, the content is just html/javascripts that point to services on our own web server.
