Have you ever wondered why a lot of unwanted advertising pop up on your screen? Isn't it annoying when you are surfing on the web and you get these weird ads that distract you from reading your article or from writing your email? It is like the worst thing that can happen to an internet user. You are dealing with Adware software that is gathering your personal information...

So what is now Adware? Adware is any computer program that displays advertisements while they are running. These advertisements can be displayed in your web browser, in a pop-up window, in special toolbars, or within the host program. Adware can also gather specific information about you like your habits or your interests and then send through a background internet connection without letting you know about it. This allows the vendors of the adware to send you targeted advertisements and collect general statistics.

There are two types of adware: Parasitical and legitimate. Parasitical adware programs are illegal and similar to spyware parasites. They often have some of their functions. They install themselves without asking you for permission and run all the time on the computer. These parasites are not so dangerous though because they will only collect your personal information for marketing and advertising purposes. But however, it is annoying in anyway, and a lot of people doesn't want their personal information to be sent, not even for marketing and advertising purposes.

On the contrary, legitimate adware programs are not dangerous for you because they don't collect any information about you, they just send advertising on your computer. A lot of proper advertising-supported products such as Opera web browser or Eudora mail client are in this category. Vendors of these products use advertising as a legal revenue model that allows distributing high-quality commercial software for free.

How does adware infect you? Adware parasites are different than viruses. They don't spread by themselves. Mostly, they must be installed as any other software with or without your content…

There are three major ways that adware parasites can get into your computer:

1. Some adware vendors trick you by presenting you adware as a useful tool such as a powerful web search service or a fast download manager. Lot of users download and install programs like this and at the end it comes out that the program is useless or ineffective. Even if users uninstall the program the adware components stay in their system and are fully functional.

2. Lots of free, advertising-supported, or shareware products like Kazaa or Exeem contain small add-ons in order to work properly, and these add-ons are actually third-party spyware or adware. When you uninstall the program, you may have the adware or spyware still in your system.

3. Some illegal advertising programs can be installed into your system by using the Internet Explorer's ActiveX controls or exploiting certain web browser vulnerabilities. The vendors of these adware tools run unsafe and insecure websites filled with bad codes or they create unsafe advertising pop-ups. And whenever you visit such a website or click on one of these advertisements that script instantly installs a parasite into your system in the background, so you don't even notice that something was installed on your computer.
