What do viruses have to support the idea that they are living

I don't know if you mean, what should viruses have to be living, if it's so:

They must be cellular, meaning they should have a cytoplasm a cell membrane and some organelles (at least ribosome).

But if you mean to say what in common they have with livings:

I can say that they have DNA, thats common both with viruses and livings.
