Update your software
If you use Windows XP, one way to help prevent spyware and other unwanted software is to make sure all your software is updated. First, visit Microsoft Update to confirm that you have Automatic Updates turned on and that you've downloaded all the latest critical and security updates.
Adjust Internet Explorer security settings
You can adjust Internet Explorer’s security settings to determine how much—or how little—information you are willing to accept from a Web site. Microsoft recommends that you set the security settings for the Internet zone to Medium or higher.
To view and change your current Internet Explorer security settings:
1.In Internet Explorer, click Tools, then click Internet Options.
If you're running Windows XP Service Pack 2 (SP2) and you use Internet Explorer to browse the Web, your browser security settings for the Internet zone will be set to Medium by default. Internet Explorer in Windows XP SP2 also includes a number of features to help protect against spyware and many other kinds of deceptive or unwanted software.
Tip: Beware of messages warning you that you sent e-mail that contained a virus. This can indicate that the virus has listed your e-mail address as the sender of tainted e-mail. This does not necessarily mean you have a virus. Some viruses have the ability to forge e-mail addresses.
Use a firewall
While most spyware and other unwanted software comes bundled with other programs or originates from unscrupulous Web sites, a small amount of spyware can actually be placed on your computer remotely by hackers. Installing a firewall or using the firewall that's built into Windows XP provides a helpful defense against these hackers. Learn more about firewalls.
Windows Live OneCare is a comprehensive, subscription-based PC health service that includes a two-way firewall, full antivirus protection and monitoring, automatic PC maintenance, and automatic file backups.
Surf and download more safely
The best defense against spyware and other unwanted software is to avoid downloading it in the first place. Here are a few tips that can help protect you from downloading software you don't want:
·Only download programs from Web sites you trust. If you're not sure whether to trust a program you are considering downloading, ask a knowledgeable friend or enter the name of the program into your favorite search engine to see if anyone else has reported that it contains spyware.
·Read all security warnings, license agreements, and privacy statements associated with any software you download.
·Never click "agree" or "OK" to close a window. Instead, click the red "x" in the corner of the window or press ALT+F4 on your keyboard to close a window.
·Be wary of popular "free" music and movie file-sharing programs, and be sure you clearly understand all of the software packaged with those programs.
