What Is Spyware & Adware and What Is Malware?

Has your computer been running more slowly recently? Has it been crashing? Do you get pop-up ads for no apparent reason? If you answered yes to any of these questions, you may have fallen victim to malicious types of programs called "malware", a term which includes both adware and spyware.

Adware (advertising software) is a type of program, which delivers ads to your computer screen. These adware programs run in the background whenever your computer is on. This can be annoying because the ads pop up from nowhere, and often contain offensive images, but can also cause conflicts and potentially crash your computer.

There are several ways these programs can get into your system. In some cases you find a shareware program, which, for example, delivers up-to-date weather reports to your computer. You download the program and install it, and while it does give you weather reports, it also watches what websites you visit and based on the profile it builds about you delivers targeted ads to your computer screen.

In other cases, the adware program is a completely separate program, which is attached to a program you choose to install. This is almost universally the case with file-trading programs. Many adware programs also get installed just by visiting certain websites, as the sites are designed to take advantage of security holes in your web browser, especially those in Internet Explorer.

An even bigger problem is that many of these hidden programs are also spyware - spyware gather information from your computer.

Most commonly they monitor web sites you visit, but some spyware programs are what is known as "keyloggers," which is short for "keystroke loggers." These programs literally record everything you type into your computer, harvesting passwords, credit card numbers, and social security numbers.

This personal information can then be sent off without your knowledge and can be used for identity theft, potentially embarrassing you or even robbing you of thousands of dollars and your good name and credit.

Fortunately, there are ways to clean up your system if it is infected, and ways to protect yourself from future infections. There are a number of anti-spyware programs out there, but be warned: many of them are scams, which actually install more spyware and adware on your system! Most people find the easiest way to learn how to get more out of their computer and be safe at the same time, is to be shown, step by step, how to do it.
