I bought a Radtell RT-880G HT from Amazon. I want to upgrade the firmware, but Chrome and Firefox flag all the firmware versions as malware. Now I'm used to Windows whining about unsigned software. No, Bill, it's not dangerous, the vendor just didn't feel like forking over the dough to get your precious certificate. But when two different browsers raise a red flag I take notice.

What's the deal here? I went to the address in the instruction manual (radtel.com) although it redirects to radtels.com.

I also can't get the radio to communicate with the programming software, which is what prompted me to try and update the radio firmware to begin with.
