Nclam防病毒程序不能与.net应用程序一起工作

我遇到这个问题:无法建立连接，因为目标机器主动拒绝它127.0.0.1:3310。

using System;
using System.Linq;
using nClam;
class Program
{
    static void Main(string[] args)
    {
        var clam = new ClamClient("localhost", 3310);
        var scanResult = clam.ScanFileOnServer(@"C:'inetpub'wwwroot'rarextract'parts'eicar_com.zip");  //any file you would like!
        switch(scanResult.Result)
        {
            case ClamScanResults.Clean:
                Console.WriteLine("The file is clean!");
                break;
            case ClamScanResults.VirusDetected:
                Console.WriteLine("Virus Found!");
                Console.WriteLine("Virus name: {0}", scanResult.InfectedFiles.First().VirusName);
                break;
            case ClamScanResults.Error:
                Console.WriteLine("Woah an error occured! Error: {0}", scanResult.RawResult);
                break;
        }
    }
}
