i noticed that a lot of people around here are using ad-aware.
for anyone that has had this program installed for more than a few months.
if you attempt to update ad-aware, but are not getting new updates, you need to uninstall, and download a newer version. lavasoft went to build 181 recently, and no longer offer updates for the older builds. and the new build works MUCH better than the old one.
i was using the old ver for some time before i realized that there was a new ver out.
