• Unfortunately, setting Internet Explorer to the High security setting can lead to the browser's unleashing a fusillade of warnings and permission pop-ups every time you visit a site. The solution is to add the sites that you access often to Internet Explorer s Trusted Sites list: Choose Tools, Internet Options, Security, click the Trusted Sites icon, and then click the Sites button. Enter the Web address, click Add, and repeat as necessary. Be sure to uncheck Require server verification (https:) for all sites in this zone. When you're finished, click OK twice.

        Block JavaScripts site-by-site in the Firefox browser via the NoScript plug-in.

• 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. 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.

• 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.

• 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.)

• 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 in-boxes. In Microsoft Outlook 2003, click View, Reading pane, Off. 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).

• 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.
