Another spam!

Why is it everytime that internet comes back on there's a spam waiting? Well, there is...... If it's not business proposal, partnerships, mystery money, what not, it's things I'm not supposed to be getting which is about drugs. And there's no surprise when there is another one in the spam folder about Viagra tablets! It's getting beyond a joke, and I don't find it funny at all, but if Yahoo customer care can't help each time I contact them about this case, then I'm going to have to close my account and create a new mail account from thousands elsewhere!
