Is it because:
- Like the original trojan horse statue, it would have done nothing/been pointless if soldiers weren't filled inside of it to attack. Thus a trojan virus isn't useful unless the attacker who gave you the virus is there to do something remotely?
- Or is it because the Troys weren't expecting the statue to be filled with soliders. Thus a trojan virus you aren't expecting to be a virus?
- Or is it both/other?
