Not reading this newsletter can help you detect a virus or worm on your computer. How? Some malware will search your unread messages and reply to the sender, attaching themselves. Therefore, if you leave this message unread, an infected message will be sent to Allan Dyer, who will send a warning back. Exactly this happened to one of our subscribers, whose machine was infected with W32/Badtrans.B.
Unfortunately, this is not a reliable, or foolproof method. Other viruses avoid unread messages, and send themselves to address book entries, or addresses found in the Internet cache, or a hundred other alternatives. It is better to follow the SafeHex Guidelines and keep your machine clean, instead.
