Yes, it kind of is. I is apart of the services running by the Dell OpenManage Client Instrumentation Application. It is possible that this application was downloaded at the same time SA was installed. Open manage/Dell Instrumentation allows you to monitor the health of you system via various applications. Dell.DCF.UA.Bradbury.API.SubAgent.exe is a part of dell Update services and doesn't have any alert about this product.   
Hi there, Yesterday I downloaded the Dell Support Assist on my laptop. However, I found a series of files, such as “Dell Instrumentation”, “Dell Diagnostics “, “Dell User Session Agent”, “Dell Tech Club” and “Dell.DCF.UA.Bradbury.API.SubAgent.exe” we’re downloaded as well as the SA was downloaded. I wonder if those files are normal and safe and officially from Dell Support Assist? I’m just afraid that those are not the proper ones for my laptop because I haven’t seen those before (especially the “Dell.DCF.UA.Bradbury.API.SubAgent.exe” one because it seems a bit strange). [IMAGE]   Tell me if anyone knows something about it! I appreciate it!
Unknown files with the SA?
