Well I decoded the rest of the program, they were lazy hackers I guess since they used a tutorial about encoding and followed it to the letter. Parts of the program were triple encoded though...
Anyway the jist of it is, is that it uses the WebFolder? exploit, which only works on Internet Explorer 6. If you have Firefox or IE7 or anything else its ok. You'll also need to have Quicktime and WinZip? on your system for it to do what it wants to do. In the end it puts lala.jpg.exe on your computer. If you have visited an are unsure if you have been infected run an updated anti-virus check. If you have no anti-virus get AVG Free Anti-Virus, it is free for personal use.
They really need to remove that blacknet url from their site... sorry about removing the warning earlier.
