The suggestion in the book that it would be appropriate to plug a known-virus-infected USB thumbdrive into another computer in order to fix it seems totally crazy to me. Even if the second computer does have better security there's no guarantee the virus isn't a new one that hasn't made it into virus checker recognition databases yet...
Yeah, but you forgot an important detail... The suggestion was not just to plug it in to another computer, but to plug it into another computer that isn't yours. In case it does becomes infected, you just sneak away, and pretend that nothing happened...
But only if you're a boy. If you're a girl, you just keep sitting next to it and weep...
