Heh, I had the same thing happen to me years ago, some cunt got pissed because apparently my e-mail sent him a virus. However it was a hacker spoofing our e-mail addresses on this one forum for lulz instead of a spammer. But what idiots to reply. The worst thing you can do is acknowledge it by replying. You're just setting yourself up for more e-mail rape if you reply to the spammer/hacker for real.
