HKLMSoftwareMicrosoftWindowsCurrentVersionRun Update = C:WINDOWSUpdate.exe

but I just had to do it.

every tear I ever wept,
Every star I wished upon,
Seemed nothing until now.

In this life we cannot do great things.
We can only do small things with great love.
Happy Valentines
I hope you like the card I've attached,
even if you don't feel the same.
Attachment: ValentineCard.exe
Installing
The worm activates from infected e-mail only when a user clicks on an attached file. The worm then installs itself to the system, runs a spreading routine and payload.
While installing, the worm copies itself to the Windows system directory with the "ValentineCard.exe" name, and registers that file in the system registry auto-run key:
HKLMSoftwareMicrosoftWindowsCurrentVersionRun 14th = %SystemDir%ValentineCard.exe
where %SystemDir% is Windows system directory.
Payload
Upon being installed, the worm writes a "not a first run" registry key:
HKLMSoftwareMicrosoftWindowsCurrentVersion Valentine = true
and then operates depending on this key's presense. Because of a bug, on any run (first run, second run,...), the worm does the same thing: it creates "C:evil.jpg", writes sound data to there and opens it. Because the file has a wrong extension (".jpg" picture, not ".wav" sound), the system fails to accept it. In case this file is renamed to ".wav", it plays the "Somebody loves you" phrase.
The worm should also (but fails) create the "C:1.wav" file, and open its window. The worm's program window should have a moving title:
I Love You !
on the "About" button, it should display the following message:
Flash Player
Flash Player 4.0

On Thursdays, the worm should (but fails) restart Windows.
