I had to knock off a star for this:We've ordered upwards of 10 of these, in similar configurations.  All new units get a malware scan before deployment and we've been surprised to find that about every 4/5 units purchased (by ratio) have come preloaded with PUP & Malware. While the PUP can be dismissed, the detections we are seeing of malware are of a specific variant "Adware.ChinAd", linked to QILU Inc (A Chinese pharma company). I love these little things because of their form factor, and they fit our industrial applications beautifully. I do however recommend that the seller be sure in the future to remove this sort of software from future stock, or we may have to consider other vendors.
