Could have a lot of meanings! Maybe just because that's a small Developer, not well known?! Other very well known Developers getting much more 'Hit's' at Virustotal, just as one example. I'll run that apps on a few machines for to test, while all those machines are on either DMZ or totally unprotected connections, just the best for testings like this! My own system is behind Smoothwall and highly protected, that I wouldn't use for such testings! As always, it's up to any user what he/she run or not run!
It cannot be the reason, there is probably something else. There is absolutely no information about it. Even the website isn't any kind of information. Only much-much exaggerated a noise.
As I've to admit now, after testing a bit, I didn't like that apps, and for sure would not recommend to other further on!! Not because it's bad, in fact, it works well! Just how the developer tries, as most of the others for such apps, to push the user's to 'upgrade' to pro, means: let the user pay for it!! That's simply scamming! For me, Freeware (and Free for Personal use) means: It's full version for to use it! And not just for about 50% of the selected process! From my point of view, this topic could be closed right away! And a Happy New Year to everybody!
