What is adware, spyware, and malware?
Adware is software designed to push advertising out to internet users, most commonly through advertising banners and pop-up windows. Adware is often packaged with computer programs and is installed along with those programs. The program developers contend that the adware helps them recover their development costs and ultimately keeps costs down for the consumer.
While the concept for adware seems sound, critics point out many problems with the system. Adware is often installed surreptitiously -- you may not be given a chance to choose whether or not you want it. To complicate matters further, many adware programs are not listed under the Windows "Add/Remove" programs and don't include uninstallation procedures or instructions. When a computer is running multiple types of adware, it can be rendered completely useless -- system resources are tied up delivering advertising in one form or another.
Some adware includes code to track your personal information and pass it on to third parties, without your knowledge or consent. Such software has been labeled "Spyware" and is the subject of intense outcry by internet privacy groups.
Spyware is a class of software that gathers information about computer users without their knowledge or consent. Like adware, spyware is often packaged with other applications and is installed as part of that applications setup routine. However, some spyware can install itself on your computer as a "drive-by" download, through computer viruses, or through deceptive internet links.
The primary difference between adware and spyware is the issue of consent. Software that collects information about you with your consent is not spyware, so long as you are made aware of what data is being collected, and what that data will be used for. Spyware doesn't give you this information -- it relies on secrecy to collect information and push it out to advertisers or other parties.
Malware is the name given to software that has been developed to do harm to computer systems. This "malicious software" includes computer viruses, worms, and Trojan horses.
How do I know if adware, spyware or malware is installed on my computer?
One of the best indications you can have that your computer is running adware or spyware is the sudden and unexplained appearance an excessive pop-up ads. While some websites open pop-up windows as you click through them, adware and spyware may generate pop-up ads even when you aren't browsing the internet. If you're using a dial-up connection, your computer may attempt to dial your ISP anytime it detects certain actions or keystrokes.
There are a number of tools available that can detect and even remove adware, spyware and malware. Some of these tools are available at a modest price, and may offer a free trial period. Some are available free to home users.
IMPORTANT -- These tools are NOT a substitute for a reputable, up-to-date anti-virus program. While they may detect some types of malware, they are not specifically designed to protect against computer viruses. Always make sure you have an antivirus program with updated signature files running on your computer.
