hmmm ... I've just run it here and there is nothing in the program about posting the log. Could the forum have been talking about posting it after a run of the program ?
All I did was to download and run it. I did opt to run it just the once (Hitman gives you the option to install or run once) and it seemed to work just fine.
One other possible tool I can think of is the Avira rescue disk. You have to download the ISO and burn it to CD, then boot your computer with the CD. There is no updating to do (they release a new version several times a day with all the latest signatures) and although it is primarily an anti-virus tool, it does check for trojans and other malware too. You can get it from

Try Hitman first on the run once basis, and if that doesn't work try Avira
