At the time of writing this, I have not become aware of any detection by Avast! of duqu. However (and the blog that I have provided a link to below states the problem more ably than I could), the real hazard is any malware that exploits the unpatched Windows bug which exposes Windows to all sorts of malicious manipulations.

Hi hake,
Apparently you are not aware what was posted here: http://forum.avast.com/index.php?topic=37542.msg705869#msg705869
Another free detector toolkit can be found here: http://www.crysys.hu/duqudetector.html

Hi Asyn,
I installed the hotfix, see http://support.microsoft.com/kb/2532445 and will remove it when the new official patch will be in. I did not have any issues since I have Microsoft FixIt Center,

Note: DuQu installs a keylogger in order to record keystrokes and collect other system information.
Something interesting here:
DuQu is NOT self-replicating

It still only applies to Windows 7 systems though.

Hi YoKenny,
@Asyn, Thanks for that right hotfix, the other one is also a gaping developing mistake that can be abused. So W7 owners should fix both issues.
@YoKenny and @Left123, Thanks for the additional info. The clever DuQu malcreants sure know what vulnerability windows to open and what won’t get patched…they make “all the skeletons that are out there in the MS cupboard” rattle to their own advance,
