Spammers flooded the Internet with millions of e-mails peddling counterfeit drugs as remedies and seeking to steal credit card data to exploit worries over the swine flu outbreak. Many of the e-mails direct recipients to websites for fake online pharmacies. In some cases, the websites simply use the ploy to steal credit card data. McAfee estimated that the swine flu spam, which began trickling out over the weekend, accounted for 3 to 4 percent of all e-mail spam on Monday. Governments around the world rushed to reduce the impact of a possible flu pandemic on Monday as a virus that has killed 103 people in Mexico and spread to the United States and Canada also reached Europe.
