My symptoms are the exact same as his. A few weeks ago, I got this nasty thing, ctv.exe (with several random numbers after the 'ctv') on my computer. Despite AVG detecting it and removing it, it would always reappear soon. I tried to remove it with a whole bunch of programs and none of them helped. It didn't appear to do anything at all, though.
Today, my computer started acting strangely, despite me not doing anything out of the ordinary the previous day. AVG detected 'Trojan horse Agent2.ZNG' on a scan so I removed it. The computer would randomly make sounds, for example the standard Microsoft click sound would play and once or twice an advertisement would play (if it helps, it was an ad for Mucinex). I found over ten iexplore.exe processes in the task manager and killed them all, and the noises stopped. (that was foolish of me, but I didn't see this forum before then) I have a feeling that next time I start the computer though they'll be back.
Here is the HijackThis log, thanks in advance for any help:
