US electronics retailer Best Buy has pulled its range of Insignia digital photo frames after discovering the devices were infected with PC viruses.

The 10.4in models were thought to have been infected during production in China. Best Buy has not officially identified the virus but claims it is an "older virus, which is easily identified and removed by current anti-virus software".

Best Buy also says the virus can only infect Microsoft Windows PCs once an affected photo frame has been plugged into the system. Cameras, USB flash drives and all types of memory cards connected to the photo frame will not be infected.

Reports of digital products being contaminated with viruses seem to be popping up more frequently, perhaps because so many modern electronic devices now ship with components that include writable memory. According to McAfee, users should check out manufacturers' processes for ensuring media is malware-free before plugging any removable storage devices into their PC.

"Find out if all devices, or just some, are checked and what happens if an infection is discovered? Also verify that their processes do not include any connections to other devices after their scanning procedure, making sure infections won't be introduced later downstream," says Joe Telafici, vice president of operations for McAfee Avert Labs.

Once you have purchased a device, there are a few simple steps you can take to ensure you don't end up infecting your computer if it does have a virus on it.

"Disable the Windows AutoPlay feature, use up-to-date anti-malware software, make sure it is turned on and set to scan removable drives. Finally manually scan the entire drive after first connecting the device, with autoplay disabled. If the scan comes up clean, you’re all set. A little up-front planning can go a long way to staying malware-free," adds Telafici.
