Spybot S&D - seeks and destroys adware and spyware
and adware can make your PC really sick. Spybot Seek and Destroy is
not the cure for the common cold but it can help keep your PC from getting
too sick. Spybot is usually recommended as "must have" for
anyone surfing the internet on a regular basis. I've used Spybot for over
two years now and it keeps improving it's detection of bad programs that
try to make my computer a mess. Spybot now includes the TeaTimer
application which is an intrusion
detector. TeaTimer detects new programs trying to get into your PC
that change the Windows and Internet Explorer settings.

Quote from the website - Spybot - Search & Destroy can detect and remove spyware of different kinds from your computer. Spyware is a relatively new kind of threat that common anti-virus applications do not yet cover. If you see new toolbars in your Internet Explorer that you didn't intentionally install, if your browser crashes, or if you browser start page has changed without your knowing, you most probably have spyware. But even if you don't see anything, you may be infected, because more and more spyware is emerging that is silently tracking your surfing behavior to create a marketing profile of you that will be sold to advertisement companies.
