We use Avast Anti-Virus, and it is very good. However, when we update a setup exe file to the web and download, Avast has sometimes reported that it's reputation is low (because we have just updated it). Do not select "Abort the connection", but select "Complete the download". In addition, if you have also selected to run programs in the Avast Sandbox, then the first time you run the dnc4U installation, and the subsequent dnc4U program (and optional plugins), it will first run in the sandbox. When Avast has run for a while, and has found no problems - you should then click "Continue Execution".
