Shawn Wildermuth, the ADOGuy has a post about a spate of e-mails saying YOUR PAYPAL.COM ACCOUNT EXPIRES. Don’t open the attachment (meant to look like a link to the PayPal website)! It contains a mass-mailing worm designed to collect your credit card information.
See SARC for more info.
Or just use a Mac to check your e-mail (and do everything else for that matter) and avoid bullshit like this all together.
It’s all IBM’s fault for abandoning OS/2.
