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 behaviour to create a marketing
profile of you that will be sold to advertisement companies.
