I just cleaned that virus off my neighbor's computer. If you read the writeup on it, it actually infects your computer WITHOUT clicking on the attachment.
*whoa* just blew away a set in stone rule there right?
Well, sorta. The problem is that Outlook is so helpful that it "clicks" on it for ya. All you have to do is preview the message, or pull up the text. Outlook executes a script in the email that then launches the virus.
Summary: All you have to do is use outlook to get nailed, you don't have to click on the attachment.
Now, if we want to blame Brangwen for infecting his computer, here's how we can do it.
There has been a patch out for over a year that fixed this vulnerability in IE and Outlook.
Sorry Brangwen, couldn't get you off the hook altogether.
Moral of the story: Don't use Outlook, or at least keep it patched if you do.
