Spyware is a general term used for software that performs certain behaviors such as advertising, collecting personal information, or changing the configuration of your computer, generally without appropriately obtaining your consent. You might have spyware or other unwanted software on your computer if:
Spyware is often associated with software that displays advertisements (called adware) or software that tracks personal or sensitive information. That does not mean all software which provides ads or tracks your online activities is bad. For example, you might sign up for a free music service, but "pay" for the service by agreeing to receive targeted ads. If you understand the terms and agree to them, you may have decided that it is a fair tradeoff. You might also agree to let the company track your online activities to determine which ads to show you.
Other kinds of unwanted software will make changes to your computer that can be annoying and can cause your computer slow down or crash. These programs have the ability to change your Web browser's home page or search page, or add additional components to your browser you don't need or want. These programs also make it very difficult for you to change your settings back to the way you originally had them. These types of unwanted programs are also often called spyware.The key in all cases is whether or not you (or someone who uses your computer) understand what the software will do and have agreed to install the software on your computer.
There are a number of ways spyware or other unwanted software can get on your system. A common trick is to covertly install the software during the installation of other software you want such as a music or video file sharing program. Whenever you are installing something on your computer, make sure you carefully read all disclosures, including the license agreement and privacy statement. Sometimes the inclusion of unwanted software in a given software installation is documented, but it may appear at the end of a license agreement or privacy statement.
The majority of spyware is adware. The purpose of an adware program is to capture so-called “anonymous” data for targeted advertising. Adware is usually just an annoyance, but in some cases can cause greater difficulties. The less common second classification of spyware programs is called malware. Malware is any program designed to cause problems with the normal use of a computer or for the user of that computer. Examples of malware include viruses, Trojan horse programs, and certain forms of hijacking spyware. These forms of spyware are written to collect personal information such as passwords, credit card numbers, and social security numbers for identity theft and fraud. Many of these can change default program settings to allow an attacker access to the computer, or monitor a user's keystrokes to gain information. The information is then sent off to the attacker to use as they see fit.
Spyware can be a very good marketing tool. Companies which produce spyware gain lucrative contracts from many companies for the service they provide. Targeted advertisements are very effective. Because the applications target users of a particular site, they can be helpful to the users of that site by directing them to other, similar sites and services. Unfortunately, like most other things online, it is easily abused. This aggravates users; some feel that they are under attack, and others are offended by some of the materials that appear in pop-ups from adware and spyware. Over-reaching advertisements don’t benefit the advertiser either. If no one clicks on the pop-up, the advertiser is wasting advertising dollars.
Several problems present themselves when a user has spyware on their system
Pornographic advertising
Spyware which creates targeted advertisements can be a problem. The targeted ads will be created from information such as websites and advertisements visited previously. If an adult user and a minor are using the same computer, this can be a problem. If the adult user visits a pornographic site, the minor could receive targeted advertisements which contain pornographic material. In some cases the targeting of ads can be for pornographic advertisements without anyone having visited adult sites.
Computer resource hijacking
Some spyware allows the unauthorized use of computer resources. This can include running programs while a PC is not busy. However, increased use of a computer processor increases the wear and tear on the components, and reduces its functional lifetime. In some cases resources are used for malicious purposes, such as mailing spam or viruses, or actually using the computer to commit crimes.
Spyware errors
Programming errors in the way a piece of spyware is written can also cause problems. A piece of spyware may expire, yet keep trying to send information to a disconnected server. This would send error messages to the user, causing worry and irritation.
Losing control of your PC
Spyware can cause a user to lose control of their PC. Changes to the web browser's homepage and to other settings can be made without the user's knowledge or permission. These changes can include turning off security protection so the spyware can communicate with external resources, making them potentially very dangerous.
Removing the spyware installation
Removing spyware can be a huge chore. Many spyware programs offer an “uninstallation” option which either does not work as advertised or actually installs more spyware.
Tips to keep your computer free of spyware
Disable third party cookies
“Cookies” are used by many pieces of spyware or Web sites to watch where the user has previously been and to record information for future visits. They reside in your Web browser's cache directory, and each is tied to a specific Web site or service.
Enable prompting for software installation.
By default, Internet Explorer (many spyware problems are known to target Internet Explorer specifically) will allow the installation of ActiveX controls on your computer. These include such spyware products such as “Gator,” a well known spyware application. Without these more restrictive settings, spyware can be installed without your knowledge just by visiting some sites. With the following settings turned on, spyware must be authorized to be installed. That means that you need to grant permission by clicking OK or Yes or something like that when your computer asks you if it’s ok to install. That gives you the chance to see it, and delete it or prevent its installation. Note that these protections only work for spyware installed directly from the Web.
For spyware in e-mails or spam, you may not get that warning. A good rule of thumb for e-mail is that if you don’t know the person sending it to you, and it contains only a vague reference, part of a word, or something you don’t use in the subject, then you should probably delete it unopened. E-mail can open small programs that connect your computer to a Web site or server to let others know you are looking at that e-mail – which in turn gets you more spam. It’s a vicious and hard-to-break cycle. To change your settings in Internet Explorer to reduce spyware installation without your knowledge, read on.
To disable automatic installation of programs in Internet Explorer, take these steps:
1. Click on the Tools menu in Internet Explorer, and then on Security.
2. Make sure the setting is set to “Medium” or “Custom.”
3. Click on the Custom Level button.
4. Under the 'ActiveX controls and plugins' area, select these options:
- Download signed ActiveX controls – select Prompt
- Download Unsigned ActiveX controls – select Disable
- Initialize and script ActiveX controls not marked as safe – select Disable
- Run ActiveX controls and plugins – select Prompt *
- Script ActiveX controls marked safe for scripting – select Prompt *
* The last two options may cause annoyance, as they will prompt you to run the ActiveX application each time. These can be set to “enable” if they cause too many problems, but will be less secure. The first three should be set exactly as marked.
Don't run file-swapping software
Most free file-sharing applications contain spyware. If you install one of these programs, you run the risk of getting bundled spyware. While not all file-sharing sites have this problem, many do. If you must use file-sharing sites, check for online reviews to see which ones are best to use and contain less (or no) spyware.
Read the EULA
EULA stands for “End User License Agreement” and is the large block of legal text that is displayed before each program. While time consuming, reading these notices can let you know if spyware is installed on a system. Unfortunately, often times this is impossible or very difficult because of the length or complexity of the EULA in question. Again, online reviews can help with this.
Set your Web browser's history to one day
This will remove session information which can be used by spyware programs for tracking information.

Use a firewall product
There are two methods of running a firewall, through hardware or software:
- Hardware firewalls are fairly cheap (about $100), do not usually need to be upgraded, and can easily be added to a network. They take the form of a physical device which is plugged into the user's home network between their outside network connection and computer inside.
- Software based firewalls are run through a program on the computer, and are somewhat more flexible.
Use an antivirus product
Modern antivirus scanners now detect and remove many pieces of spyware, in addition to other forms of malware. Remember to keep your antivirus program up to date, as new viruses come out daily. It is a good idea to start up your computer, then update your antivirus program before you check email or visit any Web sites. Many people update weekly, but these days, daily is a good idea – and it only takes a few moments.
Install a pop-up blocker
This can prevent many of the pop-up ads created if spyware is installed. There are many free products specifically designed to block pop-ups
Removing spyware is often not as complicated as one might think
Just return to Muslim Web Network and download the software mentioned and your computer should be running squeaky clean - But PLEASE remember it has to be done reguarly in order to keep those nasties from affecting your system.
