THIS IS TRUE - You can confirm it for yorself by going to www.snopes.com
Emails with pictures of Osama Bin-Laden hanged are being sent and the moment that you open these emails your computer will crash and you will not be able to fix it!
This e-mail is being distributed through countries around the globe, but mainly in the US and Israel.
Don't be inconsiderate; send this warning to whomever you know.
If you get an email along the lines of "Osama bin Laden Captured" or "Osama Hanged" do not open the attachment.

Origins: There are few headlines that would grab the attention of more computer users around the world than "Osama bin Laden Captured," and that's exactly what whoever created this lure was counting on to snare unsuspecting victims who use Microsoft platforms.
"Osama bin Laden Captured" isn't a virus in itself; it's the text of a message that includes a link to a file called EXPLOIT.EXE. When a message recipient clicks on this link to view what he thinks are pictures of Osama bin Laden's capture, he can end up downloading an executable Trojan known as Backdoor-AZU, BKDR_LARSLP.A, Download.Trojan, TrojanProxy.Win32.Small.b,or Win32.Slarp. Clicking the embedded link in the "Osama bin Laden Captured" message auto-executes a file called "EXPLOIT.EXE," which exploits a known security hole to download the Trojan. According to McAfee Security:
The Trojan opens a random port on the victim's machine. It sends the Port information to a webpage at IP address 188.8.131.52. The Trojan listens on the open port for instructions and redirects traffic to other IP addresses. Spammers and hackers can take advantage of compromised systems by using the infected computer as a middleman, allowing them to pass information through it and remain anonymous
this is a bit old
However the lesson learned is still applicable. Don't open files attached to emails that are suspicious. Don't click links to emails that are suspicious. Email is just like your regular mail. Would you open a package you were not expecting, from somebody you do not know?
ETA: Make sure you have virus protection and that it is up to date.

I most definitely would open a snail mail package addressed to me.
I do not even bother opening any email if I don't recognize the sender, let alone file attachments.
