Some people have a clean desktop other people have the total choas in the front of them. I speak about "Windows Shortcut Files" aka .LNK files. The shortcuts to applications, documents and other files. Most of the computer noobs use the desktop and the shortcuts very often, why not, the installation programs ask always to create a desktop shortcut. So this is a good way to find victims to infect (eg PE EXE files), if the shortcut file (.lnk) knows where the linked application or document is, we know it too (or must scan the .lnk file to know it).
