I use the [Security] effect to play this card, then it was deleted during that same turn. In such cases, can I return this card from my trash to my hand at the end of the turn?
No, you can't. In such cases the card remains placed in your trash.

When an opponent's Digimon isn't deleted by this card's [On Play][When Attacking] effect, can I specify 1 of my opponent's suspended Digimon and prevent it from unsuspending during my opponent's next unsuspend phase?

What happens if this card is flipped over upon a security check from an opponent's Digimon's attack in a state where a "your opponent's [Security] effects don't activate" effect has activated?
Since the [Security] effect didn't activate, the battle proceeds normally. At the end of the battle, this card is trashed.
