Antivirus Antispam software review
Keyloggers, Hijackers, Backdoors.
What is Spyware? Spyware is any kind of software that gathers and transmits information about you and your behavior without your knowledge, according to the security experts .Spyware comes in many forms and goes by many names. You may not realize that your PC is infected with spyware, but you may notice that it takes longer than usual to start-up or connect to the Internet.
Adware is the name given to the software that delivers those annoying pop-up ads based on which websites you've visited, and its presence can slow your PC down to a crawl. The toolbars that you plug into your web browser may also contain spyware. While most toolbars are helpful, others do some unexpected things. For instance, a common toolbar is WhenU.SearchNow, which can hijack your search results, presenting you with search results that are different than if you were not running it.
Hijackers are software that takes control of communications. Again, there are many forms of hijackers. A browser hijacker alters your computer's browser settings so that you are redirected to websites that you had no intention of visiting.
Some forms of spyware are annoying or offensive, but spyware like keyloggers are downright dangerous. Keyloggers can record every word you type or send over the Internet. Criminals use keyloggers to capture your passwords, account numbers and other personal information, which they can use for identity theft, fraud or other illegal activities. Criminals can also plant backdoors on your computer.
Backdoors are software that criminals use to gain unauthorized access to your computer. Using a backdoor, a criminal can do virtually everything that you can do on your computer when you're in front of it -- even though he might be on the other side of the world. Backdoors can be used to control computers as part of a "botnet." Botnets are a serious problem, taking advantage of unprotected computers connected to the Internet. With more computers at home that are connected to the Internet via always-on broadband connections, individuals who don't keep their computer security protections current are putting themselves at even greater risk. Once part of a botnet, criminals can use your computers without your knowledge or permission to send spam, viruses or conduct other unwanted activities.
