Even though your smartness level amazes me, the poster of this trojan (
) seems to outperform that level.
In short, the trojan doesn't work (it's supposed to download a trojan, but it doesn't, because of a, let's say misconfiguration).
Never run obvious viruses. Btw, Virustotal shows nothing because his file attempts to download the actual trojan - that's why the downloader itself contains no "bad" code Virus scanners could detect.
If you want to be sure your system is not infected, make sure there is no process called "system.exe" (NOT "System", that one is fine).
Btw, an interesting fact: There were only two people here in the past months who posted trojans - but they created far more than 30 threads with different user accounts.
