Go to the local junkyard and snag up an old machine that ran 98 or - my favorite - ,Windows ME. Millineum Edition was bulletproof - and around for such a short time - nobody ever wrote any malware that bothered it.
I ran it online foy YEARS with no virus protection - and the damned laptop still works.
