Spyware is one of the fastest-growing internet threats. According to the National Cyber Security Alliance, spyware infects more than 90% of all PCs today. These unobtrusive, malicious programs are designed to silently bypass firewalls and anti-virus software without the user's knowledge. Once embedded in a computer, it can wreak havoc on the system's performance while gathering your personal information. Fortunately, unlike viruses and worms, spyware programs do not usually self-replicate. Where does it come from? Typically, spyware originates in three ways.
The first and most common way is when the user installs it. In this scenario, spyware is embedded, attached, or bundled with a freeware or shareware program without the user's knowledge. The user downloads the program to their computer. Once downloaded, the spyware program goes to work collecting data for the spyware author's personal use or to sell to a third-party.
Beware of many P2P file-sharing programs. They are notorious for downloads that possess spyware programs. The user of a downloadable program should pay extra attention to the accompanying licensing agreement. Often the software publisher will warn the user that a spyware program will be installed along with the requested program. Unfortunately, we do not always take the time to read the fine print.
Some agreements may provide special "opt-out" boxes that the user can click to stop the spyware from being included in the download. Be sure to review the document before signing off on the download. Another way that spyware can access your computer is by tricking you into manipulating the security features designed to prevent any unwanted installations. The Internet Explorer Web browser was designed not to allow websites to start any unwanted downloads. That is why the user has to initiate a download by clicking on a link.
These links can prove deceptive. For example, a pop-up modeled after a standard Windows dialog box may appear on your screen. The message may ask you if you would like to optimize your internet access. It provides yes or no answer buttons, but, no matter which button you push, a download containing the spyware program will commence. Newer versions of Internet Explorer are now making this spyware pathway a little more difficult.
Finally, some spyware applications infect a system by attacking security holes in the Web browser or other software. When the user navigates a webpage controlled by a spyware author, the page contains code designed to attack the browser, and force the installation of the spyware program. What can spyware programs do? Spyware programs can accomplish a multitude of malicious tasks. Some of their deeds are simply annoying for the user; others can become downright aggressive in nature. Spyware can: *Monitor your keystrokes for reporting purposes. *Scan files located on your hard drive.
*Snoop through applications on your desktop. *Install other spyware programs into your computer. *Read your cookies. *Steal credit card numbers, passwords, and other personal identification information. *Change the default settings on your home page web browser.
*Cause your computer to run slower. *Deliver annoying pop up advertisements. *Provide the user with no uninstall option, and places itself in unexpected or hidden places within your computer making it difficult to remove. How can I prevent spyware? There are a couple of things you can do to prevent spyware from infecting your computer system. First, invest in a reliable commercial anti-spyware program.
There are several currently on the market, including stand alone software packages such as AdAware Alert and Noadware. Anti-spyware programs can combat spyware by providing real-time protection, scanning, and removal of any found spyware software. As with most programs, update your anti-virus software frequently. As discussed, the Internet Explorer (IE) is often a contributor to the spyware problem, because spyware programs like to attach themselves to its functionality. Spyware enjoys penetrating the IE's weaknesses. Because of this, many users have switched to non-IE browsers.
However, if you prefer to stick with Internet Explorer, be sure to update the security patches regularly, and only download programs from reputable sources. This will help reduce your chances of a spyware infiltration. And, when all else fails? Finally, if your computer has been infected with a large number of spyware programs, the only solution you may have is backing up your data, and performing a complete reinstall of the operating system.
