Being in the software development world, I can tell you why virus software may many times raise alarm about software from small foreign makes, even when it doesn't actually contain malware. Many times these companies don't bother to digitally sign their software. Code signing is a way to make it easier to detect if there were unauthorized modifications to software (like how viruses and malware piggy back on other software) or if it was software that was not actually released by the publisher (trojan horses that look like legit software).

As for Setec, it seems you have to install the driver for it work and you must manually check which port the adapter is connected to (look in your device manager).
