My AV software Avast send the information to there labs when I first installed but came back as the software is fine, it does this every time I reinstall windows and my AV software..
In my case it is because it is not a well known program and isn't digitally signed with a trusted root CA such as Microsoft, so it will be picked up as potential harmful software by antivirus software, that is the explanation I got back from Avast when I contacted them.
But it always comes back as been fine then Avast takes it out of the vault and lets you open the program
It is Free from any viruses and I have never had a problem with Skyline in this way once the Avast lab has gotten back to say that there is nothing wrong with it.
