Why doesn't the NiceGuy.A virus exist?

I'm fairly certain this is a fictional virus. But, I don't think I've ever encountered anything similar IRL. I wonder why such a virus doesn't exist? Perhaps the same people who might make a "nice virus" have an ethical dilemma about writing a virus in general, regardless of it's intended purpose?

In any case, I'd totally get behind a virus that forced an IE6 upgrade! :)

It would probably be illegal to release such a thing regardless of intentions, so the risk would seem to exceed the reward.

If it actually does what it says it does, thats awesome...
