Basic Info

SmartScreen is a Microsoft filtering tool designed to detect and block suspicious and malicious sites, applications and files. The program checks the safety of websites and downloads and tracks malware and phishing attempts. In some cases, it may be unwanted, and you may want to disable it.


Registry

Key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer

Type: REG_SZ

Value: SmartScreenEnabled

Data: Off

 
Group Policy

1.  Navigate to Computer Configuration > Administrative Templates > Windows Components > File Explorer

2. Double-click on Configure Windows Defender SmartScreen

3. To disable the SmartScreen filter, select the radio option Disabled

 

Keep SmartScreen Enabled and Whitelist an App

Right-click the EXE and select Properties from the context menu.

In the Properties window, go to the General tab. At the bottom, you will see a Security section that reads, The file came from another computer and might be blocked to help protect this computer. Next to it is a box called Unblock. Check it and grant admin permission to execute the change.


Unblock using PowerShell

unblock-file -path “path\to\file”


Add Unblock Files to Context Menu

Create reg file and apply the following reg values; test on file afterwards.

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\*\shell\powershell] @=”Unblock Files”
[HKEY_CLASSES_ROOT\*\shell\powershell\command] @=”C:\\\\Windows\\\\system32\\\\WindowsPowerShell\\\\v1.0\\\\powershell.exe
Unblock-File -LiteralPath ‘%L'”

 

Disable Downloaded Files from being Blocked in Group Policy

1. Navigate to User Configuration > Administrative Templates > Windows Components > Attachment Manager

2. In the right pane of Attachment Manager, double click on Do not preserve zone information in file attachments.

3. Select Enable


Registry

Or, create reg file and apply the following reg values

Windows Registry Editor Version 5.00

AI – C# – Chatbot with Random Responses

Posted on

This is a chatbot I created to demonstrate two main concepts: Scanning inputs, and returning random responses. With this, you can help the chatbot build its intelligence by adding a variety of acceptable inputs and relative responses. The program will randomly choose from those responses. Written and tested in Visual Studio 2017.

The dialog form is where you will converse with Jarvis. The top field is an input textbox. The Jarvis responses are in a form label that gets updated. The full project: VS_Project.zip

Form1.cs

using System;
using System.Linq;
using System.Windows.Forms;  // Win Form

namespace WindowsFormsApp2
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

String s;

int i;

Random r = new Random();

private void textBox1_TextChanged(object sender, KeyEventArgs e)
{

if (e.KeyCode == Keys.Enter) {

s = textBox1.Text.ToLower();

// input cleanup
s = s.Replace("'", "");
s = s.Replace(".", "");
s = s.Replace(",", "");
s = s.Replace("?", "");

Logic();

}

if (e.KeyCode == Keys.RShiftKey) textBox1.Text = null;

}

public void Logic()
{

// greetings
bool user_1 = new[] { "hello", "hi", "yo", "greetings", "hello jarvis", "hi jarvis" }.Any(c => s.Equals(c));
String[] pc_Response1 = { "Hello. How are you?" };

// greeting responses
bool user_2 = new[] { "im good", "good", "im great", "i am good", "im doing fine", "im okay" }.Any(c => s.Contains(c));
String[] pc_Response2 = { "That's great. What's going on?", "Good. What's happening?", "Okay, that's great. What's happening?" };

// leaving
bool user_3 = new[] { "leaving", "i gotta go", "im leaving", "got to go", "bye" }.Any(c => s.Contains(c));
String[] pc_Response3 = { "Okay, nice meeting.", "Later, my friend", "Okay, good bye" };

// check true for output
if (user_1) { OutputMessage(pc_Response1); }
else if (user_2) { OutputMessage(pc_Response2); }
else if (user_3) { OutputMessage(pc_Response3); }
else { NoAnswer(); }

// session
user_1 = false;
user_2 = false;
user_3 = false;
}

public void OutputMessage(String[] msg)
{
i = r.Next(msg.Length);
this.output.Text = msg[i]; textBox1.Text = "";

}

public void NoAnswer()
{
String[] output = { "I do not understand.", "Can you rephrase the question?", "My responses are limited. Ask something else." };
this.output.Text = output[i];
textBox1.Text = "";
}
}
}
