There are a lot of PC users that know little about "Spyware", "Mal-ware",
"hijackers", "Dialers" & many more. This will help you avoid pop-ups, spammers and
all those baddies.
What is spy-ware?
Spy-ware is Internet jargon for Advertising Supported software (Ad-ware). It is a
way for shareware authors to make money from a product, other than by selling it to
the users. There are several large media companies that offer them to place banner
ads in their products in exchange for a portion of the revenue from banner sales.
This way, you don't have to pay for the software and the developers are still
getting paid. If you find the banners annoying, there is usually an option to
remove them, by paying the regular licensing fee.
There are thousands out there, new ones are added to the list everyday. But here
are a few:
Alexa, Aureate/Radiate, BargainBuddy, ClickTillUWin, Conducent Timesink, Cydoor,
Comet Cursor, eZula/KaZaa Toptext, Flashpoint/Flashtrack, Flyswat, Gator, GoHip,
