Can signing executables prevent antivirus quarantining?

Question

My C# application is being quarantined by Symantec. If I sign my application with a good certificate, will it prevent this?

Answer 1

If you're being rated as suspicious, the quickest way to resolve it would probably be to submit a white listing request.

Since the software has been deemed suspicious by a heuristic/reputation based system, there's no guarantee that signing it will automatically white list it (although it will most likely raise the possibility)
