Opponent plays "Antibiotic" :D ermm.. some of these are overpowered and unfair (Final Despair being one) but I really like the idea of these cards infecting opponents cards. I would definitely use this deck, but you should sort out the OP cards. lower the "1000 life points" cards.

 

And you should make a continuous spell that increases all virus cards ATK and DEF by 400 or something like that, as a boost (virus rush? or increased infection?)
