Each new wave of computer viruses, spies, and spam may have you ready to dust off your typewriter, but PC security can be effective without being a chore. To keep your computing safe from current and future threats, we've distilled our security advice down to the basics. These ten quick and easy tips will help protect your hardware, software, and data.
1. Patch automatically: Ensure Windows is set to update itself. In XP, click Start, Control Panel, Security Settings (if you're in Category view), Automatic Updates. In 2000, choose Start, Settings, Control Panel, Automatic Updates. In both versions, verify that 'Automatic (recommended)' is selected. You can also have Windows notify you before it downloads an update, or you can install the update manually. (The steps and options are only slightly different in Windows 98 and Me.)
2. Don't wait for Windows: If your PC has been off for more than a few days, don't wait for Windows' automatic update to kick in. Make the Windows Update site your first Internet stop. Also, there may be a lag between when a patch is available and when Windows Update pushes it to you. Microsoft releases Windows patches on the second Tuesday of each month, so to be safe check for updates manually every couple of weeks. And don't forget to set your antivirus and anti-spyware tools to update automatically (or check weekly for updates yourself).
3. Use XP's security monitor: Windows XP Service Pack 2's most welcome addition is the Windows Security Center , which alerts you when your PC's firewall and antivirus protection are disabled or out of date. Still, XP's own firewall protects you only from inbound pests; it doesn't alert you to suspicious outbound traffic (see "Tweak Windows XP SP2 Security to Your Advantage" for more). We recommend that you disable the XP firewall and instead use Zone Labs' (ZoneAlarm) or another third-party firewall program that protects both ways.
4. Make your file extensions visible: Some viruses masquerade as harmless file types by adding a bogus extension near the end of their name, as in "funnycartoon.jpg.exe," in hopes your system is set to hide such extensions (the default in Windows XP and 2000)--you see '.jpg' but not '.exe'. To make these troublemakers easier to spot, open Windows Explorer or any folder window and click Tools, Folder Options, View. Ensure that the option 'Hide file extensions for known file types' is unchecked.

5. Keep Internet Explorer safe: Many people find IE 6's Medium security level too obliging to ActiveX controls and other small programs, or scripts, that the browser runs on your PC. ActiveX and _JavaScript enable such useful Web features as order forms and security scans, but they also may run malicious code and give attackers access to your system. To make IE safer, click Tools, Internet Options, Security, Custom Level, select High from the drop-down menu at the bottom of the Security Settings dialog box, and click Reset, Yes, OK.
6. Make Firefox more secure: The only way to block JavaScripts on a site-by-site basis in the Mozilla Foundation's free Firefox browser is to download and install the NoScript add-in that was created by Giorgio Maone. NoScript places a warning bar at the bottom of all the Web pages you visit that use _JavaScript. Click the bar to see options for allowing scripts on the site (permanently or temporarily), blocking scripts, and other operations (see the NoScript screen below). The program can also stifle Flash animations and other Firefox plug-ins, but keep in mind that going Flash-less means you'll be missing out on some of the Web's richest content (along with all of those great dancing ads). Although NoScript is freeware, the author does accept donations at
www.noscript.net.
7. Handle e-mail links with care: If a virus infects your PC, chances are good it arrived piggybacked on e-mail. To reduce your risk of an e-mail-borne infection, don't click links in suspicious messages (the text in the message may mask the actual Web address). Instead, enter the URL in your browser's address bar manually, or go to the site's home page and then navigate to the page in question.
8. Scan attachments for viruses: Run each of the e-mail attachments you receive through your antivirus software before you open them. Rather than double-clicking the attachment to open it instantly, save the file to a drive on your PC, open Windows Explorer, right-click the file, and choose the option to scan it for viruses. (Better yet, set your antivirus software to scan incoming and outgoing e-mail automatically.)
9. Close the preview pane: Some maleficent messages need only be opened in your e-mail program's preview window to do their dirty work. That's why we recommend that you close the preview pane in all of your inboxes. In Microsoft Outlook 2003, click View and make sure 'AutoPreview' is unselected. In Outlook Express 6, click View, Layout and verify that 'Show Preview Pane' is unchecked. In Mozilla Thunderbird, click View, Layout and confirm that 'Message pane' is unchecked (or press <F8> to toggle the preview pane on and off).
10. Read your mail in plain text: Since many e-mail pests rely on HTML code to achieve their nefarious goals, you can stop them in their tracks by viewing your messages as plain text. In Outlook 2003, click Tools, Options, Preferences, E-mail Options and check Read all standard mail in plain text. In Outlook Express 6, choose Tools, Options, Read and click Read all messages in plain text. In Mozilla Thunderbird, select View, Message Body As, Plain Text.
