That's odd. I have been using Trend for several years and it's never complained when connecting any of my Garmin GPS'es. Since it's just a USB disk, it's certainly possible that a virus could infect it though. Will be interested to hear what Garmin and Trend say about this. It's not something I've heard of on any of the GPS forums.
A couple years ago there was a thread at GPSReview about virus software flagging an infected file on a user's Nuvi. Just looked quickly and couldn't find it, which may be better because it was a bit contentious. IIRC, the OP was from South America and when he contacted his local Garmin representative they eventually admitted that a machine they used to pre-load maps spread a virus to some units.
Did trend flag a specific file as a problem? I vaguely recall some other old discussion of false positives coming from GarminDevice.xml. That is a file which is regenerated every time your Oregon starts up. It describes the capabilities of the device, including software version, available memory, etc. and is used to tell software like Webupdater, Basecamp and other Garmin software what your unit can do.
