Because I am not a skilled user, I ;
1- tried Defender and scanning offline [recommended]worked with the laptop but not the desktop -any guess why? I am concerned that it is either on my end or a glitch.
It just says it is broken now and try again later.
2- I think simrick was saying not to use a program that broadcasts outgoing. If so, which would you recommend for the medium skilled user to learn? I think Miller's comment about outgoing disturbing and confusing the novice is accurate. This is indeed a puzzle if Defender will not function as it should offline and even then it is broadcasting outgoing.
