What is Spyware

Copy write Microsoft Corp.

We've all heard the cliche, "There's no such thing as a free lunch." This is as true on the Internet as anywhere else. Whether it's through advertising, or through the use of your personal information, you're going to have to pay somehow. The key is to understand what you're agreeing to and what you're willing to pay for something that claims to be free.

There's a new type of software out there that you may have heard about. It's called spyware and the most common way it gets on your computer is when you are downloading something else that claims to be free.

What is spyware?

Spyware is software that collects personal information from you without first letting you know what it's doing and without letting you decide whether this is OK or not. The information spyware collects can range from all the Web sites you visit to more sensitive information like usernames and passwords. You might be the target of spyware if you download music from file-sharing programs, free games from sites you don't trust, or other software programs from an unknown source.

Spyware is often associated with software that displays advertisements, called adware. Some advertisers may covertly install adware on your system and generate a stream of unsolicited advertisements that can clutter your desktop and affect your productivity. The advertisements may also contain pornographic or other material that you might find inappropriate. The extra processing required to track you or to display advertisements can tax your computer and hurt your system performance.

This is not to say that all software which provides ads or tracks your online activities is bad. If you sign up for a free music service and in return for that free service the company offers you targeted advertisements, it might be a fair tradeoff. Likewise, tracking online activities can be useful when displaying customized search content or personalized preferences at an online retailer.

The key is whether or not you (or another user of your computer) have been properly notified of what the software will do and that you have provided consent to have that software installed on your computer. In other words, is the software being deceptive in what it does or how it gets onto your computer?

What is deceptive software?

Spyware and unauthorized adware are two examples of "deceptive" software. Deceptive software includes programs which take over your home page or search page without first getting your permission. There are a number of ways deceptive 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 adware in a given software installation is documented, but it may appear at the end of a license agreement or privacy statement.

Sometimes deceptive software gets silently installed on your system without any warning at all. If you use Internet Explorer as your Web browser, this can happen if your Internet Explorer security setting is set to its lowest value. Make sure to keep this setting at the medium level or higher. Doing so will help you control what is being installed on your computer. (We'll discuss this more in a moment.)

Have you ever had an experience where you were repeatedly asked to accept a download even after you said "no"? Creators of deceptive software often use such tricks to get you to load their software. If this happens to you, do not click "yes". Instead, try to close the Web page that first asked you to accept the download by hitting the "X" in the corner of the window. Alternatively, quit Internet Explorer and restart it to begin browsing the Internet again. If you visit a Web page that continually displays these tricky pop-up windows, that Web site may not be worthy of your trust.

Read on to learn how to help avoid infecting your computer with deceptive software and to find out what to do if you are already infected.

Step 1: Adjust your Internet Explorer 6 (Web browser) security settings

You can adjust your Web browser's security settings to determine how much—or how little—information you are willing to accept from a Web site. The higher the security level, the lower the risk. The downside: using the highest security levels may make Web sites less usable.

By default, Internet Explorer 6 strikes a balance. When you first install Internet Explorer, it classifies all Web sites into a single zone (the Internet zone) and assigns everything medium level security. When you are using this level of security, Internet Explorer should ask you to confirm that you want to download a file, unless you have previously indicated that the Web site or publisher is trusted. If you change the security level to "low," Web sites will be able to download software to your computer without telling you, so be careful when using this setting. If you need to change the security level to low for some reason, change it back to medium or higher as soon as possible.

Step 2: Don't take downloads from strangers

The best defense against deceptive software is not to download it in the first place. Here are a few helpful tips that may help guard against deceptive software.

Step 3: Look for signs of deceptive software on your computer

Deceptive software is intended to run without your knowledge, but there are a few ways you can tell if your system is infected.

Step 4: Use a tool to help detect and remove unwanted software

Several companies offer free software that will check your computer for unwanted software. These tools may help you determine if you have installed unwanted software and may help you remove it.

If your Internet provider doesn't offer a spyware removal (or similar) tool, ask people you trust for a tool they recommend. Keep in mind that removing unwanted software with these tools may mean you will no longer be able to use a free program that may have come with it.

Tip: Keep your detection and removal tool up to date. Many manufacturers offer an option to check for updates automatically when you go online. If this feature isn't available, check the manufacturer's Web site regularly for downloads. Either way, be sure to update frequently.

Step 5: Keep Windows up to date

The last step in helping keep yourself safe from deceptive software is making sure your Windows software is always current. You can do this by visiting Windows Update and by enabling Automatic Updates. For detailed instructions, see our story about updating your Microsoft software.

Take time to protect your personal information

Keeping your computer off of the Internet will help you avoid deceptive software—but that wouldn't be practical. You can still enjoy all that the Internet has to offer. Just be cautious about who you do business with online, especially if something appears to be free. The hidden cost might be uninvited spyware or adware. A good question to ask yourself is "Would I let this stranger into my house?"
