friendship screen saver virus

Today I got about 30 50 100 copies of this virus in my e-mail. Luckily my computers aren't vulnerable to it, because one is Mac OS X (on which the virus won't run) and on my Windows box I read mail with Eudora, not any version of Outlook or Outlook Express (which it exploits to send itself further).

Please do not double-click on the Friendship Screen Saver attachment if you receive it from anyone, and Outlook and Outlook Express users, please consider switching to some other e-mail program so your machine doesn't get unwittingly recruited as a virus-distributing stooge.
