Adware or advertising-supported software is any software package which automatically plays, displays, or downloads advertising material to a computer after the software is installed on it or while the application is being used. Adware in this form does not operate surreptitiously or mislead the user, and provides the user with a specific service, but Adware and spyware are similar to viruses in that they can be malicious in nature.

Adware has been criticized because it usually includes code that tracks a user's personal information and passes it on to third parties, without the user's authorization or knowledge. Adware or advertising-supported software is any software application in which advertisements are displayed while the program is running.

The main reason why Adware is built into programs is because it helps recover programming development costs, and helps to hold down the price of the application for the user (sometimes even making it free of charge) and, of course, it can give programmers a profit, which helps to motivate them to write, maintain, and upgrade their software.

Adware companies make their money by distributing thousands upon thousands of ads on the internet. Adware is considered a legitimate alternative offered to consumers who do not wish to pay for software. It is now big business and there is a lot of money to be made.

Adware is also known as malware, sneakware, or spyware, adware is a type of software program that's installed without a users consent or knowledge while another program is being installed on the computer. Adware is related to spyware, in that they both invade your computer through software that usually is installed without the user's consent or knowledge.

Spyware

Spyware is considered a malicious program and is similar to a Trojan Horse in that users unwittingly install the product when they install something else. Spyware can even change computer settings, resulting in slow connection speeds, different home pages, and loss of Internet or other programs.

Spyware can exploit this design to circumvent attempts at removal. Spyware can also come bundled with shareware or other downloadable software, as well as music CDs. Normally it does not directly spread in the manner of a computer virus or worm: and generally, an infected system does not attempt to transmit the infection to other computers.

Spyware, which interferes with networking software commonly, causes difficulty connecting to the Internet. Spyware, along with other threats, has led some Windows users to move to other platforms such as Linux or Apple Macintosh, which are significantly less susceptible. Spyware programs which redirect network traffic cause greater technical-support problems than programs which merely display ads or monitor users' behavior, and so may more readily attract institutional attention.

Software

Software authors that use spyware do not care about anyone's privacy. Software designers get paid big bucks to design things that work effectively and safely. The software that is supported by advertising is often called "adware".

Software developers are now very sensitive to malware concerns and will provide a lengthy explanation of just why the bundled software is necessary, in the cases when they actually do need to use bundled software.

Spyware is computer software that is installed surreptitiously on a personal computer to intercept or take partial control over the user's interaction with the computer, without the user's informed consent. Since they tend not to install software if they know that it will disrupt their working environment and compromise their privacy, spyware deceives users, either by piggybacking on a piece of desirable software such as Kazaa, or by tricking them into installing it (the Trojan horse method).

Some "rogue" anti-spyware programs masquerade as security software, while being spyware themselves. The distributor of spyware usually presents the program as a useful utility?for instance as a "Web accelerator" or as a helpful software agent. In some cases, spyware authors have paid shareware authors to bundle spyware with their software. Some spyware authors infect a system through security holes in the Web browser or in other software. The spyware author would also have some extensive knowledge of commercially-available anti-virus and firewall software.

Windows

Windows Defender is free and therefore should be a part of your desktop anti-spyware collection. If you have an adware infected computer Windows may take longer to load, hyperlinks may not work or they may even take you to a new site. Many spyware components would also make use of flaws in Javascript, Internet Explorer and Windows to install without the user's knowledge or permission.

Malware

Malware is software designed to infiltrate or damage a computer system without the owner's informed consent. Malware includes computer viruses, worms, trojan horses, so it's software that damages your system, causes instability, or exhibits antisocial behavior such as changing settings or interfering with a computer's registry and security settings. Malware writers began to design their programs so that they would reinstall automatically if removed, sometimes using different file names.

Conclusion

If you want your computer to be a stable safe, clean environment then do a Google search for "adware" you will find a great free product called ad-aware, this is one product that I have used for years to keep my computer safe and it's a product I highly recommend.
