Pay an insane amount of money for it...

As long as you are in the Battle Phase, then yes, you could use Trap Jammer against Crush Card Virus.
get a yugioh gold series, collectors pack, open it, then the sub-box in the middle will have crush card virus in it. Return the other mini-boxes, if the store keeper allows.
similar cards would be eradicator epidemic virus and deck devastation virus.
Sorcerer of Dark Magic has a Quick Effect that can be chained to any spell speed 2 Trap card (meaning he can't stop a Counter Trap). So when Crush Card Virus is activated, he can chain his effect to it. His effect will resolve, negating the activation and effect, meaning Crush Card Virus does not resolve - nothing is destroyed.
In my opinion it would be a gold rare crush card virus.
It is forbidden in Advanced format, and limited to one in Traditional.
You can chain Spell Speed 2 or 3 effects to Dark Hole. Crush Card Virus is Spell Speed 2, so yes, you can chain it to Dark Hole's activation.
Yes, it does not target, so can destroy Obelisk, and will destroy Ra too if his ATK is high enough.
either gold series or shonnen jump championship series prize packs.
crush card virus - destroys everything with good attack until the the third draw phase but VERY expencive
No, unless a card has the infinity sign next to "SPELL CARD" or "TRAP CARD", it will not remain on the field after activation, unless it specifically says it does, like 'Swords of Revealing Light'.However, even though Crush Card Virus is no longer on the field, its effect still "lingers" and remains so until three turns later. After activation, its effect cannot be reverted, negated, or removed until three turns later.
