DPC High CPU usage

Hi.

I've read all topics about DPC, but none of them seems to solve the question.

When uTorrent is up, my ProcessExplorer shows DPC Cpu usage far beyond 30%, making life hard in my Vista system. Even the mouse gets stuck and hard to move.

If I shut uTorrent down, everything goes normal.

I've downloaded the RATTV3 program, but I have no idea what to look for into the log. The log is the following:

I'm using ZoneAlarm, but it seems not make any difference. The symptoms are the same with or without ZA instaled.

Any help would be very welcome :)

Thanks!
