Any one hear of the Unix virus that targeted servers and used a loophole and patched it. No, honest!
I read it in a computer mag and they named it. They were not impressed by the cavalier attitude but must have secretly applauded the benefits.

BTW isn't the plural of an "us" an "ii" making virii as it does with radius and fungus or is virus an exception? Not that I am being pedantic 'cos I don't know fer sure.
