Scan your PC with one simple click and without having to register any contact information. Comprehensive malware detection Find both known and unknown viruses, worms, Trojans, spyware, phishing, and other internet threats. You don't need anti-virus. Simply look at the contents of one of the drives. Are they empty? Fine, then you are ok. Pull random samples out and check them. If you asked the vendor to put files on the drive, such as promotional materials for you company, then makes sure that the files match precisely. Remember: do this from a machine with the latest patches. For example, you don't want to do this with a Windows machine with autorun enabled, or the virus will hop to your machine, infect it, then hide its files from you. A recent Mac or Linux machine will probably be safe. Beware that USB drives can have multiple 'partitions', one of which might appear as a CD-ROM drive. Check not just the one you expect, but these additional partitions as well. All this assumes the device acts as a normal flash drive. Hackers can do something more nefarious, such as pretend to be a keyboard and inject keystrokes that log the hacker in. It's so unlikely that you don't have to worry about it, but if you do, then you'd have to hire an expert to test them. Lastly, because of these security concerns, promotional USB drives are a very bad promotional items. Most Fortune 500 corporations and the military have rules dictating that such drives should be destroyed, and never plugged into a computer. ![]() The simplest option is actually to set up a machine with a couple of antivirus/antimalware products on it, with no connectivity to other networks, and plug the devices in. It is not foolproof by any means, but to get a deep assurance you would have to examine the driver files and that is likely to be time consuming and uneconomic. Depending on where you are, you may have a strong contract with the company that sold them to you, but even if not, if you find malware, you could offer them the option of providing you with clean ones or never getting your business again. Edit: since this was written more sophisticated USB malware has appeared. There seems to be no perfect way to avoid USB malware. Use good security hygiene such as no plugging in unknown USB devices and not lending out a USB drive. In other words after using it to give a file to a colleague just tell them to keep it. I have seen viruses spread via USB sticks in an lab environment. Windows computers can be set to automatically run software off a USB stick and there might be an autorun.inf file and an executible on the stick that you are concerned with. What you want to do is quickly look at the USB stick with a computer that is safer than the PC's you are going to be using with the sticks later. You can use a Mac, Linux box, or a secured Windows PC with autorun disabled. The Mac method is easiest and Macs are pretty common. Using a Mac: create a file on the desktop called autorun.inf. To do this open Terminal.app from the Utilities folder in the Applications folder. Type cd ~/Desktop then touch autorun.inf to create the file. Now type sudo chmod 444 autorun.inf or sudo chflags uchg autorun.inf or both.
