Advertising-supported software is a way to make money without the necessaty for the software
users to pay for this software; the advertisements that will pop up while using this kind of
software will pay for the costs. There's nothing wrong with that.

Unfortunately, this is quite often not the case. Several adware based programs secretely lurk in
places from your pc where they shouldn't occur; in the browsers history for example, and will
install components that will be loading advertisements. This happens even if you don't run the
software that installed them. Even in case one uninstalls such a software, these components
will not be uninstalled and continue to do their work.
Many of these "adwares" - one could call them "spyware" by now - work in ful stealth, and are
hardly detectable, sending privacy-related information from your system elsewhere. This is a
very serious matter.

How to find out if your pc has been infested with this malware?

Fortunalely, there are some freeware programs that will detect them, and offer you the
possibillity to remove them. Instead of naming them all, we just recommend using the best
at this very moment. That freeware program is called Adaware . A somewhat more
difficult program to handle spyware, but very worthwhile, is SpyBlocker . Both Adaware and Spyblocker work flawlessly in conjunction.

A perfect freeware double check for Ad-aware is Spybot Search & Destroy . This tool
comes with lots of very useful extra features.
