They’re Out To Get You: Preventing Spyware, Viruses On Your Computer

by D.B. Grady


You're not paranoid. They're out to get you.

You probably have spyware on your computer. There's a good chance you've got a virus or two. Your personal files are likely insecure, and your hard drive might be shared for the entire world to see. In real world terms, you've not only left your car unlocked, you've left the windows down, the doors open, the engine running, and a sign on the dashboard reading FREE CAR.

If you are infected, you will probably need to visit a local computer repair shop. Malicious software is notoriously difficult to remove, and the wrong combination of deleted files can often result in a computer that doubles as a boat anchor, doorstop, or shooting range target. If your computer is in proper working order, however, there are a few practices you can implement that will keep you both protected and secure.

Windows Update (sometimes, in its more expansive mode, called Microsoft Update) is a utility built into Windows that keeps your computer up to date. As bugs and security vulnerabilities are discovered, and new features are added, Microsoft releases patches and service packs free for download. Windows Update automates the installation process, checking the files of your operating system against a central repository at Microsoft, and applying the newest versions.

This may be the most critical part of your computer housekeeping routine, as an out-of-date operating system is as secure as an ATM card with its password written on it. Windows Update can be found under the Start menu, in the Programs folder, or oftentimes in the system tray (bottom-right of the screen, next to the clock) as a yellow shield pleading with you to "click here to install updates."

Every Windows-based computer needs antivirus software. Popular programs include McAfee Total Protection ($34.98/year), Norton Antivirus ($39.99/year), and Trend Micro Antivirus ($39.95/year). Free alternatives include AVG Free and Avast Home Edition. Upon installation, allow the antivirus to download and apply the most current virus definitions, and run a full system scan.

Once your computer is protected, like Windows Update, make it a priority to update your antivirus software regularly. (Note that virus protection software can often be acquired for free though public libraries, colleges, government agencies, and the military. Check their websites for more information.)

Spyware is often the easiest malicious software to install and the hardest to delete. It often appears in friendly, apparently helpful website popup ads warning that, "Antivirus 2009 has detected 32 threats on your computer! Would you like to remove them?" Clicking either yes or no results in the same thing: an infected computer. Unless you are computer savvy, the safest course of action when faced with such prompts is to exit your web browser entirely.

Two of the most effective and anti-spyware utilities on the market are Spybot and Windows Defender. Both programs are free, and in both cases, the installation and maintenance procedures are similar to those of antivirus software. Upon setup, allow the programs to update, and run a full system scan. Update the spyware definitions regularly.

While an updated operating system, strong virus-protection, and a spyware monitor are crucial to safe computing, they will not do the job on their own. It is up to you to adopt smart practices to keep your computer secure. This means never opening email attachments from people you don't know. It means carefully reading the screen whenever an unexpected window is prompted. (Blindly clicking "Next" is a recipe for disaster.)

It also means avoiding the more unsavory areas of the Internet—most notably file-sharing sites such as Kazaa and Limewire. In addition to the legal ramifications of downloading copyrighted music and software, every illicit file runs the risk of bringing with it malicious software.

It's a dangerous web out there. If it seems like "they" are out to get you, it's because they are. Thankfully, safe computing doesn’t require an advanced degree. All it takes is a little discipline and a couple of free programs.

Which Computer Should I Buy?

By D.B. Grady



"I'm thinking of buying a laptop computer. Which one do you recommend?" None. Seriously, think of the headaches that come with a computer. Viruses. Spyware. Twitter. Do you really want to do that to yourself? Wouldn't you rather spend a thousand bucks on a nice cruise to the Bahamas? I've never seen a spiral notebook crash or one of those big, green ledger-books blue-screen just after adding an entire quarter of sales figures.

But if you're absolutely determined to get a computer—think hard about those sandy beaches and umbrella drinks, though—there are fewer factors in choosing a system than you might think. While this may be the opposite of what you've heard from others, don't worry about RAM or CPUs or hard drives or anything else measured in bytes or hertz.

There are only three questions you should be concerned with:
1. Mac or PC?
2. Is the computer "comfortable?"
3. How much can I afford?

Buying a Mac used to be a big deal, akin to changing religions or moving to Canada. There were separate stores, separate software, separate peripheral supports, separate user paradigms—the decision was nontrivial, and unless one worked in video or graphics design (where the Mac has always excelled) it was rare that the hassle warranted the investment.

The Internet and Apple's remarkable marketing and engineering efforts have changed this. The Internet is the Internet, whether one owns a bottom-shelf eMachine or a top-of-the-line MacBook Pro. Email is email.

The web is the web. Macs have the benefit of being impervious to viruses or spyware, which is a bonus, but a well-protected PC is just as safe. As for program availability, all of the major players in the software business support both platforms, including Microsoft Office, Firefox, Adobe Photoshop, Acrobat, iTunes, Skype, and Picasa, to name a few.

Because Macs use Intel processors, they also have the luxury of supporting Windows XP, Windows Vista, and the upcoming Windows 7 by way of dual booting—that is, selecting on startup whether to boot into Mac OS or Windows—or through free emulation software such as VirtualBox (http://www.virtualbox.org). With regard to peripherals, from printers to external hard drives, if it works on a PC, it works on a Mac.

The real question, though, is "How does it feel?" Unless one purchases an extraordinarily expensive system in the thousands of dollars, or a second-hand pawnshop special, there is little difference from one computer to the next. A thousand dollar Dell, a thousand dollar HP, and a thousand dollar Mac have the pretty much the same horsepower under the hood. (In the case of Dell and HP, they even have the same outsourced telephone technical support staffs that employ so many in Third World countries.)

The best way to choose a computer is to visit an electronics store and play with the demo models. Is the screen bright enough, or is it too bright? How does the keyboard feel? Are the keys awkwardly placed? Is the track pad well positioned? Is the computer too small for aging eyes, or too large to lug to class every day?

Hold the computer to gauge its weight and test its durability. One doesn't need an advanced degree in electrical engineering to know whether a computer feels cheap or not.

Just as the average mid-sized sedan buyer isn't particularly concerned with torque or engine liter displacement, neither should the average computer buyer worry much about whether the central processing unit runs at 2.2GHz or 2.4GHz. Faster is always better, but in the context of playing Freecell and chatting with Aunt Thelma in Des Moines, the difference is negligible.

Indeed, that very reasoning has led to a new variety of portable computer known as the netbook. Purchased for as little as $200, netbooks are designed primarily for online use. As general computer activity moves from the desktop to the Internet, many users find there is little reason to invest in "big iron" computers at all.

The exception to this is gaming, of course. Some high school students might sooner die than accept anything less than a computer that dims the lights when it's powered on. But with the money saved by purchasing a less expensive system, one can buy an XBox 360 and enjoy hassle-free gaming.

In the end, it all comes down to price. Buy the most comfortable computer you can afford, and buy locally, if possible. The least expensive MacBook is $999, and worth every penny. But if the thousand-dollar HP is more to your liking, get it.

Whether you've budgeted two thousand dollars or two hundred dollars, there is something out there for you. Oftentimes, local mom-and-pop computer shops have staggering bargains on second-hand laptops, and personal support that doesn't require an interpreter or a passport.

No longer the intimidating beasts they once were, purchasing a computer should not be a worrisome experience requiring years of expertise. Go with your gut and a handle on your checkbook, and you'll do just fine.
But really, think about taking that vacation. On the islands, the only blue screens you'll see are in the sky and on the sea.

Review of the New Apple iPhone 3GS

By D.B. Grady



When Apple unveiled the original iPhone in 2007, I was one of the thousands standing in line, eager to be among its first adopters. This type of thinking is why so much of my lunch money was stolen in grade school. In 2008, when Apple released its successor device, I was in a different line, at the hospital, selling plasma. The original iPhone cost $599 dollars, and I was still paying it off.

But with my blood replenished and my contract up for renewal, I decided to take the plunge and upgrade to the new iPhone 3GS. Wooed by the promise of unbridled digital horsepower and a video camera, I fished out my credit card and did my part to stimulate the economy.

The iPhone 3GS improves upon the first and second-generation models in a few key areas. The most obvious is speed. It's a snappy device, capable of rendering even the most graphically intensive and overly designed website in seconds. Applications load much faster, and grind through data with greater efficiency.

The camera resolution has been bumped to 3 megapixels, and sports an innovative touchscreen auto-focus. More impressive is the video recording feature. Users can record high quality video, edit it, and upload it directly to YouTube, no computer required.

This was the feature that brought me over. Sadly, like every father who eagerly shelled out for a camcorder in the late 80s, I quickly discovered that I do nothing worth video recording. If ever I spot a UFO or Bigfoot, though, I've got just the phone for the job. Or tornadoes—this is my chance to make the evening news. And with the iPhone's bundled weather application, I'll know exactly when to expect flying cows and houses.

There is also an integrated compass, enabling developers like Tom Tom and Garmin to write iPhone-specific GPS car navigation systems. Until such software is released, though, the compass makes it a lot easier to shoot an azimuth and earn that Boy Scout merit badge. Just for the record, my house faces south. I didn't know that before I got this phone. Can one really put a price on such useful information?

Gamers especially will be pleased with the iPhone 3GS. With its faster CPU, boosted memory and 3D graphics accelerator chip, mobile gaming has a new contender. John Carmack, renowned programmer and founder of Id Software (makers of the Doom and Quake series) calls the iPhone more powerful than "a Nintendo DS and PSP combined."

If there is fault with AT&T's new flagship phone, it's AT&T. The iPhone 3GS supports the blisteringly fast 7.2 megabit-per-second HSPDA network. That's the network AT&T has yet to roll out. The iPhone 3GS offers MMS picture messaging. AT&T does not. The iPhone 3GS offers out-of-the-box computer tethering, enabling laptops to be online, everywhere, all the time.

Guess which telecom giant doesn't support this feature? (Hint: it starts with an A and ends with two Ts.) I do not claim to be a business expert, but if I ran a telephone empire, and my most valued and sought-after product offered a slew of new and exciting features, I might consider investing a few dollars to actually support those features.

AT&T is essentially selling a Ferrari, wheels not included. (Though the company promises these features will come in due course.) Still, with the exclusivity deal between Apple and AT&T rumored to end next year, users might soon be asked to choose between the two companies. Considering Apple's notoriously loyal fan base, and AT&T's general and unrelenting villainy, the executives at Verizon must already be pricing new yachts and Gulfstream jets.

If your phone contract is up and you're looking to buy, you will not be disappointed with the iPhone 3GS. The staggering list of features, the elegant design, and its battery's heroic lifespan make it worth the upgrade. And at $199 (with a 2-year contract), it is cost-competitive.

But what about next year, when another iPhone is released? This year we got a compass and a camcorder. Next year I fully expect a retractable chainsaw and electric toothbrush. I'm not worried about the price. I'm out of plasma, but I've got two kidneys. For Apple's latest toy, I'm sure I could get along fine with just one.
