Matt Kohut's previous interview with TECH.BLORGE makes it absolutely clear that he is arguing from a position of ignorance or malice about Linux.

I wouldn't bother correcting him. If you want to run Linux, you have a clear warning not to buy Lenovo. From my family's personal experience, I'm not sure I'd buy Lenovo either if I wanted to run Windows, with the amount of non-functioning vendor-specific software supplied.

Kettering Grammar School were doing this in the 1960s. See the links in Wikipedia for more information.

Here is the virscan.org scan of the DPFmate.exe file on a similar photo keyring. This scans almost clean, with the only warning being "Suspicious - DNAscan" from QuickHeal.
All sounds to me that the Walmart photo frame may be truly infected. Interesting to see if a re-scan gives the same results, after AV signature updates.
To identify my photo frame, it has USB vendor code 1908:1320, and gives dmesg output as

Hey, I always stick odd USB devices into Linux first to check them out.
For background info, this photo frame does nothing when first connected. You can set it to "transfer" mode, at which point it emulates a USB CD-ROM of 304 Kbyte size. That CD image tries to autorun the DPFmate software to compress and transfer images to the device. The photos are *not* visible on the device through normal access, must have transferred them to a hidden area. I'd be interested if anyone has more info on the USB protocols used.
