The file attachment included with this e-mail actually is the Klez worm and will infect your system if you open it. This is just one of the many forms the Klez worm has taken. It propagates by searching your computer and the Internet for e-mail addresses, so infected messages could appear to be coming from someone you know or a web site you have visited. This bit of trickery makes it particularly sinister.

This letter demonstrates one of the biggest dangers of relying on e-mail warnings to protect yourself from viruses. There is no substitute for antivirus software. It is inexpensive, readily available, and well worth the investment. Read "Protecting Your PC" in the Chain-Breaker's Library for real ways to prevent unwanted intrusions on your data and never forward another virus warning. Break this chain!
