I did a HijackThis scan, and everything seems to be alright, except for one entry that I cannot seem to find much out about.

O20 - Winlogon Notify: winqad32 - C:\WINDOWS\SYSTEM32\winqad32.dll
I searched google, and found some HJT logs that had that, but on hijackthis.de, it had a question mark and no description. As far as the google search went, there wasn't a clear description that I could find. Anyone here seen it?

I am running MSWinXP SP2...

Thanks in advance
