Not a concern, I see things like that fairly often. Uninstall the old MVT though. Sometimes if MVT is too old it wont update before running, which necessitates uninstalling and then installing the latest from https://mvt.mcafee.com/
(I believe there's website problems at the moment so the download link may not show, if so try later on).
Not a problem. It does says when I start it that it must be updated.
I didn't need to run it anyway... I was just trying because of the DCOM notices.
