This notification is only partially true. Viruses are simply not capable of "destroying" hard drives; rather, they are designed to erase, install, or modify data. Granted, this can be very annoying, but your hard drive will remain physically intact. What this particular "virus" really does, if you happen to click on a URL (link) in the email, is install a bit of software that uses your computer to send copies of itself to addresses it finds on your disk, usually for the purpose of spamming or hijacking your browser. Generally, only machines without updated patches are vulnerable.
There is absolutely no reason to send the above notice to friends and family, thereby inducing the "panic" mentioned (LOL). While there is a threat, it is of a very common type and certainly not "the most destructive ever". All that is needed is common sense and proper habits:
1) Don't open attachments in email, even from friends and family, unless you're absolutely sure what they contain. Ask people to instead put pictures and text in the body of the email (it's friendlier, anyway).
2) Don't click on hyperlinks contained in email.
3) Install the latest updates to your operating system.
4) Use antivirus protection and a firewall.
5) Disable javascript in your browser whenever possible (websites like CADO require cookies and javascript to be enabled, however).
And please don't pass on hyperbolic and misleading notifications. I wouldn't want to receive this claptrap even once, much less 25 times!
