Triona's Tech Tips

My column in today’s Northwest Herald talks about the recent uptick in hijacked email accounts. Hackers hijack your account in order to prey on your contacts by sending spam, malicious links, and outright requests for money in your name. And not just your email account… Facebook, LinkedIn, and other accounts can also be hijacked.

Here are some things you can do to protect yourself, not just from hijacked accounts but also from viruses, spyware and other Internet threats:

• Use strong passwords that are unique on every system, and change them every few months. Earlier this week I posted an article about how to create secure passwords. This is the number-one thing you can do to prevent your accounts from being hijacked.

• Use a high-quality security software suite. I used to recommend free solutions for Windows like AVG combined with Spybot or AdAware, but these days I’m finding the freebies aren’t enough to protect you. Norton and McAfee will do the job, but Norton in particular tends to take up a lot of memory which may make older machines run more slowly. I prefer AVG’s paid Internet Security Suite or Trend Micro’s Titanium Internet Security or Titanium Maximum Security. If you’re using free AVG, you can get a discount on the full AVG suite if you buy through the “upgrade from free version” option.

Whatever solution you choose, be sure it is a full suite—containing antivirus, anti-spyware, and firewall—and not just antivirus. And be sure it’s real software and not one of the many rogue security programs that are actually viruses in disguise.

Mac users, you need security software too. My personal favorite is Intego VirusBarrier or Internet Security Barrier. If you run Windows on your Mac through Apple’s Boot Camp or a program like VMWare or Parallels, try Intego’s Dual Protection options: VirusBarrier DP or Internet Security Barrier DP. These include BitDefender for Windows to protect the Windows half of your computer.

• Make sure ALL of the software on your computer is regularly updated. In one of my previous Northwest Herald columns, I talked about the dangers of old software. Here on my blog I’ve also talked specifically about the risks posed by old versions of Adobe (Acrobat) Reader and Flash.

• If you’re on Windows, use a browser other than Internet Explorer. Using Firefox or Opera instead of Internet Explorer offers you that much more protection. If you must use Internet Explorer, find out why older versions of Internet Explorer pose a greater risk of virus infection.

• Watch out for poisoned search engine results and learn how to spot bad web links.

• Never click on links or open attachments in email. Always visit the site directly. For example, if you get an email saying you have a new Facebook message, go directly to facebook.com from your Web browser instead of clicking the link in the email.

• Learn about social engineering and how hackers will do anything and everything to trick you into letting them in.

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).

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.

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.
