Block yahoo mail on computer

Here are the steps to block Yahoo Mail on a computer:

Method 1: Using Windows Firewall

  1. Open the Windows Firewall by searching for it in the Start menu or by typing "wf.msc" in the Run dialog box (Windows key + R).
  2. Click on "Advanced Settings" on the left side of the window.
  3. In the "Inbound Rules" section, click on "New Rule" in the right side of the window.
  4. Select "Rule Type" as "Port" and click "Next".
  5. Select "TCP" as the protocol and enter the port number "110" (the default port for Yahoo Mail). Click "Next".
  6. Select "Block the connection" and click "Next".
  7. Give the rule a name, such as "Block Yahoo Mail", and click "Finish".

Method 2: Using a Third-Party Firewall or Antivirus Software

  1. If you have a third-party firewall or antivirus software installed on your computer, such as Norton Antivirus or Kaspersky, you can use its built-in features to block Yahoo Mail.
  2. Open the software and navigate to its settings or configuration section.
  3. Look for the "Firewall" or "Network Protection" section and click on it.
  4. Add a new rule or exception to block Yahoo Mail. You may need to specify the port number "110" and the protocol "TCP".
  5. Save the changes and restart your computer.

Method 3: Using a Browser Extension or Add-on

  1. If you only want to block Yahoo Mail in a specific browser, you can use a browser extension or add-on.
  2. For example, you can use the "uBlock Origin" extension in Google Chrome or the "NoScript" add-on in Mozilla Firefox.
  3. Configure the extension or add-on to block Yahoo Mail by adding it to the list of blocked websites or domains.

Method 4: Using a Hosts File

  1. Open the Hosts file on your computer by searching for it in the Start menu or by typing "notepad %systemroot%\system32\drivers\etc\hosts" in the Run dialog box (Windows key + R).
  2. Add the following lines to the end of the file:
    127.0.0.1 mail.yahoo.com
127.0.0.1 login.yahoo.com
  3. Save the changes and restart your computer.

Note: Blocking Yahoo Mail may not be effective if you have already accessed your Yahoo Mail account on the computer. You may need to clear your browser cache and cookies to completely block access to Yahoo Mail.
