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. HijackThis (http://www.merijn.org/files/hijackthis.zip) is the
preferred tool to use these days. It will help to both identify and remove
any hijackware/spyware. **Post your files to http://forums.spywareinfo.com/
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.
