Probably the problem is the daemon or the client, not the qt, sorry buddy
What are you talking about?There is trojan in your archive. not the qt..oo ,really!?
zip contains: copperd.exe, copper-tx.exe, copper-cli.exe, copper-qt.exe and copper.conf
And no, what I mean is that what you are detecting can be either the copperd.exe, copper-tx.exe or the copper-cli.exe, in no case is there a Trojan, it is a false positive.
