Triona's Tech Tips

Did you know you can expand your web browser’s functionality? Extensions (also called add-ons or plug-ins) are little programs that run within Internet Explorer, Firefox, Safari, and other web browsers. While extensions offer increased options, they also pose security risks.

Some extensions are probably familiar to you. One of the most popular, Flash, lets you see video content on the Web. Flash also illustrates the risks of extensions. Viruses can enter your computer through malicious Flash content, especially if you’re running an older version of the extension. Most people don’t realize that browser extensions, like all software, need to be updated.

To solve that problem, several months ago Mozilla introduced a check for Firefox to help users find and update their extensions. Mozilla is now offering this free service for other browsers. To maximize your computer security, become familiar with the extensions you’re running. The easiest way to do that is to visit Mozilla’s extensions check page, but you can also find them under Tools>Manage Add-Ons (Internet Explorer), Tools>Add-Ons (Firefox), and Help>Installed Plug-Ins (Safari).

My tech column in today’s Northwest Herald is about how to protect your passwords and your privacy on the Internet. Remember, to create strong passwords:

• 6 to 12 characters in length
• Mix of lower- and uppercase letters and numbers
• Symbols if allowed
• Not easily identifiable (your spouse, your kids, your dog)
• Create a passphrase
  • fourscore and seven years ago = 4Score&7Yrs (don’t use this one!)
• Different password for every account
• Change your passwords regularly, at least every 3 months
• Don’t re-use or cycle through the same set of passwords
• You can write them down, but keep them in a safe place

No one is immune to having their accounts compromised, and weak passwords are often the method. So take some time this weekend to secure your world by setting strong, unique passwords for all of your accounts.

Here are links to the resources I mentioned in the article (they’re all free):

• About the Twitter worm
• KeePass password manager, available for Windows, Mac, and smart phones
• ExpandURL for expanding shortened links
• McAfee SiteAdvisor
  • and, in a similar vein, LinkExtend for Firefox

The next time you do an online search for something, pause before you click. Some of the results you receive are poisoned links to malicious sites that may infect your computer with viruses and malware.

Search engines don’t verify that keywords match results, nor that sites are free from infection. Sponsored ads are particularly notorious. If you do a search for “Windows antivirus”, the paid results are often links to fake antivirus programs just waiting to lure you in.

I advocate the use of link-checkers such as McAfee SiteAdvisor or LinkExtend for Firefox. These free add-ons indicate through red, yellow or green icons whether links are safe to visit. Even so, you should always be cautious. Make sure your security software is up to date and that you have the latest versions of programs like Adobe Reader and Flash (here’s why). You can also run Secunia’s Online Software Inspector to check the status of your security protections.

If you are using an old version of Internet Explorer, your PC is more vulnerable to viruses and spyware.

The current version of Internet Explorer (IE) is version 8, but I routinely encounter computers running version 7 or–heaven help us–version 6. Upgrading isn’t a matter of wanting all the bells and whistles. It’s a security necessity.

The longer a piece of software is publicly available, the easier it is for hackers to design viruses or spyware to exploit its weaknesses. Also, newer software benefits from advances in security research. By running the most current version, you boost your protections.

I advocate that you break the Internet Explorer habit by using an alternate web browser like Firefox. But you still need to keep up to date on your Internet Explorer patches. Because IE is a component of Windows, you are vulnerable even if you don’t use it. One rare reason you might not want to upgrade to IE8 is if you have software that isn’t compatible. Unless this applies to you, you should consider the upgrade.

You can check your version of Internet Explorer within the program by selecting About Internet Explorer from the Help menu. To upgrade, visit update.microsoft.com or click here to go directly to the download. After you’ve installed, be sure to visit update.microsoft.com again to seek out the most recent security fixes for IE8. This will provide you maximum protection.

The federal government predicts that online retail sales will reach over $235 billion this year. Here’s how you can shop safely online this holiday season.

• Before you shop, make sure you have adequate computer security protections, and that they are up to date. Where possible, consider using a browser other than Internet Explorer (like Firefox, Safari or Opera). If you must use Internet Explorer, be sure to use the latest version, and check update.microsoft.com for Windows and Microsoft Office security fixes.
  -
• You should also be sure that other programs like Flash and Adobe Acrobat Reader are up to date (here’s why). Secunia Online Software Inspector provides a quick way to do this for Windows users. Mac users should check Software Updates under the Apple menu, and visit web sites like adobe.com for common software to check for new versions.
  -
• Never shop from a public network or WiFi hotspot. Only do your shopping from a secure Internet connection, such as the one at your home or office.
  -
• See if your bank offers a virtual or one-time credit card number that you can use for online shopping. Or, get a credit card with a minimal limit (like $500) that you use exclusively for online purchases. Don’t use a debit card online, because it’s easier to get fraudulent charges removed from a credit card.
  -
• Shop with known retailers. If you’re thinking about doing business with a site you’ve never used before, do some Web searches for reviews to assess other customers’ satisfaction.
  -
• Never click an email link to reach the site. Such emails are often phishing scams trying to lure you into visiting malicious web sites. It’s safer to type the store’s Web site directly into your browser.
  -
• Only shop at sites that offer secure checkout. Look for the “https” (instead of “http”) in the address bar of your browser, but be warned that even secure sites can be compromised.
  -
• Beware of bad web links that may lead you to malicious ads.
  -
• Keep an eye on your credit card statements for erroneous charges or theft.
  -
• To avoid spam, create a separate email address for online purchases.
  -
• Print your receipts, either to paper or electronically to a PDF file. PC users will need a PDF program like FoxIt to do this. Mac users can simply select Print To PDF from the Print window.
  -
• As with anything else online, if a deal looks too good to be true, it probably is.

Mozilla Firefox has upped the ante in the fight against cybercrime with automatic checks for updated plug-ins.

Plug-ins are bits of software that work within your Web browser to provide additional functionality. Mozilla debuted this feature with a check for updated versions of Flash, a popular plug-in used to view video content. Outdated versions of programs like Flash are used to spread viruses and malware.

Firefox will run the check automatically, or you can visit this site to check your plug-ins manually. You still have to update them yourself, but Mozilla’s new feature provides a more intuitive way to do so. You can also view your plug-ins and get more information about enabling and disabling them. The check works for both the Windows and Mac versions of Firefox. It’s such a good idea I suspect we’ll see this sort of functionality added soon for Internet Explorer and Safari, the default browsers for Windows and Mac, as well as other browsers like Opera.

Mozilla says it will continue to expand this feature to include additional plug-ins, which is great news for users struggling to keep their computers free of malware and other threats.

The latest version of Mozilla Firefox 3.5 (3.5.3) includes an important new feature. It checks to see if you have old, unsafe versions of Flash, a plug-in used to view multimedia content.

Old versions of Flash are problematic because they can be used to infect your computer with viruses and other malware. It’s not always easy to tell which version you’re running, and Flash often goes under the radar screen because it’s a plug-in, not a program you run directly by clicking an icon.

Mozilla reports that 99% of Firefox users have Flash. Of the six million users who upgraded Firefox after last week’s upgrade, half of them had unsafe versions of Flash.

Firefox can’t run the Flash upgrade for you; you have to do it yourself by clicking the link to visit the Adobe site. When I visited, Adobe tried to lump some free McAfee antivirus software with the Flash upgrade; you can de-select that. You may need to approve the Adobe Download Manager (look for the yellow bar at the top of your Firefox window). Once Download Manager completes, Firefox needs to restart. A new window will appear, downloading the latest version of Flash. Finally, close Adobe Download Manager by clicking the orange button. (With all these steps, is it any wonder people don’t upgrade Flash more often?)

While the new version of Firefox 3.0 (3.0.14) also includes this Flash check, I encourage you to upgrade to 3.5.3 for greatest security.

If an alternate web browser is safer than Internet Explorer, which one should you use?

The most popular is Mozilla Firefox, available for both PC and Mac. I use it on both platforms. Another option for PC and Mac is Opera, which tends to do better with IE-insistent sites. Windows users might want to explore Google Chrome (a version for Mac is in development). And Mac users can rely on Apple’s default browser, Safari. Be sure to set the alternate browser as the default when asked. For more information on alternate browsers, please visit the Alternate Browser Alliance.

You can also install plug-ins to enhance your browser’s capabilities. I’m fond of McAfee SiteAdvisor for security. You can find Firefox plug-ins on Mozilla’s site.
