IF M$ ever has their way with the world, meaning if one day everyone is running a M$ O/S and only running current M$ software on them, then there could be a good virus...

But since currently people run varied O/S's and run many various programs on them, it would be near impossible to write a single program with viruss like attributes that wouldn't cause harm to someone, somewhere if infected.

So currently no...

While at the same time, I do agree Nachii would be the closest thing to a 'good' one that has come out recently. As it 'seemed' to have no negative intentions and only caused damage due to its method of replication/deployment - which if it wasn't designed to use semi-current mass-deployment methods and also added in code to remove itself after execution, it would probably of been completely benign...
