Windows by default has AutoPlay configured. AutoPlay (once called AutoRun in older Windows operating systems) is that little program that starts up the software whenever you connect a USB flash drive, an external hard drive, or pop in a CD or DVD. It was handy back in the old days of innocent computer use… but AutoPlay is increasingly used by evil programmers who want to spread malware and viruses. It is now recommended that you disable AutoPlay on your computer if you use USB flash drives or other portable peripheral drives like it.

There’s been a rash of infections in recent months that can be traced back to infected USB or other removable devices being used to transmit malware from one machine to another. The culprit is autorun. Even if you think you have it turned off, I’m betting you don’t have it turned off – not completely anyway.

Autorun (or autoplay, as it’s sometimes known as or confused with), is a very convenient feature of Windows that, as its name implies, allows things to happen “automatically” when you insert a removable device such as a CD-ROM, USB Memory stick or attach a device like a digital camera.

And yes, absolutely, it’s evil, and should be turned off completely as soon as you possibly can do so. The reason is very, very simple: autorun can be seriously abused by viruses and other forms of malware.

…autorun can be used to automatically launch software, either already on your machine or on the removable media. This is good when it’s the CD player software installed on your machine automatically playing the CD you just inserted, and it’s bad when it’s a virus that installs itself automatically.

There are several ways to disable AutoPlay, depending on your computer skills, and the operating system you have.

For Vista, it’s easy to disable it. Go to CONTROL PANEL >> HARDWARE AND SOUND >> AUTOPLAY. In Classic View of Control Panel, look for AUTOPLAY in the alphabetical list.

At the top, under the Menu Bar, you’ll see a box that says “Use AutoPlay for all media and devices.” Deselect it.

From there, you can customize the defaults, how Windows will handle various drives and files. It is recommended that all drives be changed to “Take No Action” in the settings.

Now be warned that this fix works in MOST cases. But you know– this is Windows we’re talking about. Depending on your operating system brand, your updates, your hair color, blah blah, this fix may not work for you. In such a case, you can download updates, or you can hack the Registry yourself to fix it. Here are some very helpful links with tutorials and screenshots if you need more information or more detailed instruction.

Ask Leo: How do I *really* disable auto-play in Windows XP?

After you have disabled AutoPlay, no window will pop up and nothing will run when you insert a USB flash drive or CD/DVD into your computer. So how do you access the drive? Go to COMPUTER, either on your Desktop or look for it in your START MENU. You will see a listing of drives there. Double-click the drive you want to open, and your portable drives files are there.

It’s just too risky in this day and age of malware and viruses and worms to leave your computer susceptible to them. It is recommended by the security geeks that you disable AutoPlay. I have learned to live without it, and love it.
