Strimage.exe

Lost Strimage.exe is a screamer program written in VB6 which spread across China in around 2005.

It has an icon of the folder in Win9X style, attempts to make the user think it's a normal folder and run it. When executed, it seems that nothing happened. However, the program has already copied itself to several system directories, deleted the original file, and set itself to the default application for opening JPEG files. So each time the user double click on a JPEG file, the program will be called to run, Then, the program will check the date on the local computer. If the date it's not Friday, Saturday or Sunday, the program will terminate itself. Otherwise, the screamer will begin the countdown for a random amount of time between 5 minutes and 15 minutes in the background.

After finished counting, the program will show its main payload, which is a ghostly girl and half of her face is a skeleton. The eyeball on the other half can move and a crying sound effect will be played. Click anywhere will exit the screamer.
