For a week or so, the firewall asks everytime if icarus.exe can connect even an allowed rule is set

Ahahah, you’ve also mentioned that your firewall settings trigger connections from any “new” application - this might be a problem that is hard to overcome - since Icarus is really frequently updated, at the least, once every month. The first thing this product does is checking for it’s own updates, downloading them and then it starts with the fresh copy of itself - then, it checks and downloads updates for the rest of the binaries. … we’ll discuss what the options are, but unfortunately it seems that having the binary static (a setup where even a strict firewall won’t trigger the popup) somewhat fights against the whole purpose of the updater - to be at the latest version allways and make the rest of the installation also new. Eventhough there are tricks, how to make the icarus.exe static, while updating other parts and DLL libraries, that are loaded into it, this whole behavior is a bit strange and may trigger any smarter firewall or IDS/IDP system as well.
