When W32.HLLP.Handy runs, it uses information in the registry to locate the KaZaA download folder and the Internet Explorer default download folder.
It prepends itself to all .exe files in both folders. It may occasionally reinfect the same file.
Other KaZaA users may download the infected files from the KaZaA download folder; this causes the virus to spread through the KaZaA file-sharing network.
