Hello

When I reboot Windows10, why am I getting four MS Word windows entitled "Document1 - word"?

Or to be more accurate, the 4th window is in fact called "Documen2 - Word"

I am also getting six popup messages called "3DxService", containing the message "The 3DxService is already running".

Is this some kind of virus?
How do I stop these from appearing?

Cheers

J
