You *must* seek updates for Ad-Aware, Spybot, etc., before each and every
use, even "right out of the box". But even then, they can't catch
everything. When all else fails, HijackThis
(
http://www.merijn.org/files/hijackthis.zip) is the preferred tool to use.
It will help you to both identify and remove any hijackware/spyware. **Post
your files to
http://forums.spywareinfo.com/ or the Spyware forum at
http://forum.aumha.org/ for expert analysis, not here.**
As part of the hunt, also update your virus definitions and then run a full
system scan. From now on, do both daily.
