Best Buy tells us that one of its Insignia brand digital picture frames has been contaminated by a virus. The only model involved is a 10.4-inch frame bearing the number NS-DPF10A. If you're downloading photos by connecting this frame directly to your computer, you may be putting your system at risk. Owners should contact the company by calling 877-467-4289. Best Buy will help you determine whether your frame is affected and will let you know how to proceed if it is. The model, which was sold over the holiday season, has been discontinued and is no longer available for purchase from Best Buy.

The virus is not a new strain, so if your system is protected by antivirus software, it should catch and isolate the infection. In addition, if you're loading photos using a memory card, the virus can't be passed along that way, according to a Best Buy spokesperson.

So far, the company has received about two dozen calls concerning this issue. Best Buy is still investigating the cause of the infection. If you have another model of Insignia frame, and notice that your antivirus software is picking up viruses when you connect the frame to your computer, call Best Buy and let them know.
