If you are sure that the software is safe and you want to use it, you can add an exception to your antivirus software. To do that, you need to open the Bitdfender program and go to Settings -> Antivirus -> Exclusion, add the installer of your software to the Excluded processes and click Allowed. It is advised to add a new Firewall rule also. To do that, go to the Firewall tab -> Settings -> Application rules -> Add rule, browse the application and click Open. Make sure that you select both Local Address and Remote Address boxes, at Network type select all boxes, go to Events and also select all boxes (Listen, Traffic, Connect). This should solve your problem.
