Driver Pci Simple Communications Controller Windows 10

There is no trace of Microsoft office on my computer and I don't think there has been for more than 5 years, but just today there appeared a drive Q labeled microsoft office click-to-run 2010 (protected). I can't remove it. All the answers on answers.microsoft seem to think that either uninstalling microsoft office will remove it or that you simply can't remove it. I'd appreciate anyone that can tell me why it's there or how to remove it.
