//Scan  
string start = Console.ReadLine();  
System.Diagnostics.Process scanprocess = new System.Diagnostics.Process();  
sp.StartInfo.WorkingDirectory = @"";  
sp.StartInfo.UseShellExecute = false;  
sp.StartInfo.FileName = "cmd.exe";  
sp.StartInfo.Arguments = @"/c antivirusscanx.exe /scan="+filePath;  
sp.StartInfo.CreateNoWindow = true;  
sp.StartInfo.RedirectStandardInput = true;    
sp.StartInfo.RedirectStandardError = true; sp.Start();  
string output = sp.StandardOutput.ReadToEnd();  
//Scan results  
System.Diagnostics.Process pr = new System.Diagnostics.Process();      
pr.StartInfo.FileName = "cmd.exe";  
pr.StartInfo.Arguments = @"/c echo %ERRORLEVEL%";   
pr.StartInfo.RedirectStandardInput = true;    
pr.StartInfo.RedirectStandardError = true; pr.Start();  
output = processresult.StandardOutput.ReadToEnd();  
pr.Close();
