Bitdefender is interfering with sourcetree, when it needs to connect to the server and sync/download/upload the files. By default all connection should go through to the server directly, but i checked the resource monitor and found vsserv taking control of the connection and causing a huge delay in performing actions.
Since this free version lacks any control whatsoever, i always have to disable the AV when i need to use sourcetree https://www.sourcetreeapp.com/.
The connection is interupted and vsserv is connecting to ec2-52-36-46-55.us-west-2.compute.amazonaws.com
Which i suspect it is doing realtime scan of the files, which doesn't happen to any other downloads i've done so far. Only via sourcetree.
