I am having the same problem downloading the new update also showing up as a TROJAN so I will not be updating the wallet.  It is quite frustrating to see all the other questions being answered but everyone is ignoring the questions of WHY IS THIS TRIGGERING as a TROJAN NOW when it never did before.  I downloaded the first wallet update and of course it will not sync to network are there any other fixes or are we still waiting for an updated wallet besides the fix update that is triggering as a TROJAN and is immediately deleted by antivirus protection.
