Better yet - reimage.
Why is re-imaging better?
And won't this whole deal work only with dynamic IP assignment? (Sorry if dumb questions...not a computer professional here...)
I am not a big fan of more legislation to cure whatever ails our society, but I would favor the death penalty for pop-up ad makers and spyware purveyors, and I would hold ISP's financially liable after the first report of a spammer on its system.
I suppose I am naive about all this, and that the out of the country spammers could never be held accountable.
