This error is a keyboard hook associated with attnaget.exe. This file is associated plug in to the kazaa music download program and is for advertising. The only thing I know is I did a windows update and then nothing worked. My daughter now states she did a upgrade to kazaa also but unsure when. It affects all windows and browsers, I later learned I would freeze up just attempting to copy files or do a find command through windows. I have removed the kazaa program and then removed the plug in uzla (something like this) which is where dshellgenerichook.dll is used. Everything is restored and back to normal. I am sure there is going to be many of these showing up. Yes for those who emailed I am running up to date virus scan. I appreciate the many emails sent to me in a attempt to fix. My kids are back on the battlenet, icq and hotmail as well as others. I am going to attempt to install this music program again over the weekend and see if error occurs again. Thanks to all I hope this helps someone else. The problem here is if you don't have two computers on-line you are into using DOS and some knowledge to find the source, or a re-load of the system which would have taken less time. I could not even open the attnaget.exe file to see what it was associated to, and there were two or three trying to do this for me, not nubies. Once attnaget.exe removed from c:\windows\system I was able to run find again and found another file associated to this and it sent me to the uzla plug in. (Not sure of spelling of the plug in).
Once again thanks to all it is nice to see others trying to help. I hope this explanation helps someone else with same problems.
