How to Block Adobe Acrobat Internet Access in Windows Firewall (2026 Guide)

By default, Adobe Acrobat updates itself in the background and frequently sends telemetry data to Adobe servers. If you hate this behavior and want to stop it, you can manually create Windows Firewall rules to block Acrobat’s internet access. The process itself is pretty simple. All you have to do is create outbound rules to prevent Adobe executables from sending data. You can do this using a simple PowerShell script I made or manually via Windows Firewall advanced settings. Let’s get started.

Before You Start

• The steps below are tested in Windows 10 and Windows 11.
• After blocking Adobe Acrobat’s internet access using Windows Firewall, you will be unable to auto-update and send telemetry. If you follow the optional steps, you will also be unable to sign in, fill & sign, and use Adobe Cloud storage or AI features.
• You require administrator rights to create firewall rules, either manually or using PowerShell.
• If you are using a third-party antivirus or firewall (like Norton, Bitdefender, or McAfee), these Windows Firewall methods will likely not work. You must block Adobe Acrobat inside that specific software’s settings instead.

Quick Navigation

• PowerShell method (the easy way)
• Manual method (the hard way, but gives you greater control)

Block Adobe Acrobat Internet Access in Firewall with PowerShell (The Easy Way)

Since we need to create multiple firewall rules to block the main app, the updater, and the telemetry services, I wrote a simple PowerShell script to automate the entire process. This is the easiest and fastest method.

If you don’t want to use the script, you can follow the manual method shown in the next section. Both achieve the same thing: create outbound firewall rules to block Acrobat’s internet access.

Open the Notepad app by searching for it in the Start menu.

Once it opens, copy (Ctrl + C) the following script and paste (Ctrl + V) it into Notepad.

# Script by Bashkarla
# Guide: WindowsLoop.com/how-to-block-adobe-acrobat-internet-access-in-windows-firewall/
# Run this as Administrator to block Adobe internet access
​
# Creating a list of executables to block (Array)
$FilesToBlock = @(
    # The main Acrobat app
    "C:\Program Files\Adobe\Acrobat DC\Acrobat\Acrobat.exe",
​
    # The updater service (blocks auto-updates)
    "C:\Program Files (x86)\Common Files\Adobe\ARM\1.0\AdobeARM.exe",
​
    # The telemetry process
    "C:\Program Files\Adobe\Acrobat DC\Acrobat\LogTransport2.exe",
​
    # The UI and Cloud components (AcroCEF)
    # NOTE: Blocking these might break the "Home" screen and "Fill & Sign", 
    # Cloud Storage, and AI Features.
    # If you want those features, comment out the two lines below with a #
    "C:\Program Files\Adobe\Acrobat DC\Acrobat\AcroCEF\AcroCEF.exe",
    "C:\Program Files\Adobe\Acrobat DC\Acrobat\acrocef_1\AcroCEF.exe"
)
​
# Loop through the list and block the executables
foreach ($FilePath in $FilesToBlock) {
    if (Test-Path $FilePath) {
        $RuleName = "Block Adobe - " + (Split-Path $FilePath -Leaf)
        
        New-NetFirewallRule -DisplayName $RuleName `
                            -Direction Outbound `
                            -Program $FilePath `
                            -Action Block `
                            -Profile Any `
                            -Description "Blocked via WindowsLoop Script"
                            
        Write-Host "Blocked: $FilePath" -ForegroundColor Green
    } else {
        Write-Host "Could not find $FilePath" -ForegroundColor Gray
    }
}

Next, press “Ctrl + S” or select “File” > “Save”. In the “Save” dialog, choose a destination to save the file (e.g., desktop), type the filename as “block-adobe.ps1“, select “All files” from the “File type” dropdown, and click “Save“.

After saving the file, right-click on the “Windows” icon and select the “Terminal (Admin)” option. Windows 10 users can select “Windows PowerShell (Admin)”.

Run the following command to navigate to the folder with the script file we just created. Don’t forget to replace the sample path with the actual path of the folder with the script file.

cd "C:\Path\To\Script\Folder"

Now that you are inside the correct folder, run the following command to execute the script. This command temporarily bypasses execution restrictions, checks if the file paths are valid, and creates outbound rules to stop Adobe Acrobat from accessing the internet.

PowerShell -ExecutionPolicy Bypass -File ".\block-adobe.ps1"

Important note: If you’ve saved the script with a different name, make sure to replace block-adobe.ps1 with your actual filename.

You are now done. From now on, Adobe Acrobat will be unable to access the internet.

To verify if the rules are correctly created, search and open “Windows Firewall with Advanced Security” in the Start menu, then go to the “Outbound rules” tab on the left sidebar. You should see the new block rules in the center panel.

You can also try updating Acrobat (Menu > Help > Check for updates) or accessing its cloud features (if you’ve blocked the AcroCEF.exe file). You should see the connection failed error message. This confirms that you’ve successfully blocked Adobe Acrobat.

Manually Blocking Adobe Acrobat Using Windows Firewall

If you don’t want to use the PowerShell script I’ve provided above, you can manually create outbound rules to block specific Acrobat executables responsible for updating, telemetry, and cloud/AI features. In fact, you can follow the steps below to block any application from accessing the internet.

This method takes a bit longer since you have to repeat the same steps for each executable. But the end result is the same.

Step 1: Press “Windows key + R” to open the Run dialog. Next, type “wf.msc“, and click “OK” to open the Windows Firewall settings.

Step 2: Right-click the “Outbound Rules” tab on the left sidebar and select “New Rule“.

Step 3: Select “Program” and click “Next“.

Step 4: Select the “This program path” option. Copy (Ctrl + C) and paste (Ctrl + V) the following path into the blank field, then click “Next“. This blocks the main Acrobat executable.

C:\Program Files\Adobe\Acrobat DC\Acrobat\Acrobat.exe

Step 5: Select “Block the connection“, and click “Next“.

Step 6: Ensure the “Domain“, “Private“, and “Public” checkboxes are selected and click “Next”.

Step 7: Enter a clear name (e.g., Block Adobe Acrobat – Acrobat.exe) in the “Name” field, and click “Finish“.

Repeat for Remaining Files:

Now, you need to repeat steps 2 through 7 for the following files to fully block updates (AdobeARM.exe), telemetry (LogTransport2.exe), and cloud/AI features (AcroCEF.exe).

1. C:\Program Files (x86)\Common Files\Adobe\ARM\1.0\AdobeARM.exe
2. C:\Program Files\Adobe\Acrobat DC\Acrobat\LogTransport2.exe
3. C:\Program Files\Adobe\Acrobat DC\Acrobat\AcroCEF\AcroCEF.exe (optional)
4. C:\Program Files\Adobe\Acrobat DC\Acrobat\acrocef_1\AcroCEF.exe (optional)

Important Note: If you want to use Acrobat’s fill & sign, cloud storage, AI features, and don’t want to break the home screen, skip the “AcroCEF.exe” paths (labeled as optional).

Once finished, check your Outbound Rules list. You should see 5 new ‘Block Adobe’ entries (or 3, if you skipped the optional AcroCEF files).

With that, you are done. To verify if the block is working, you can try updating Acrobat (Menu > Help > Check for updates) or accessing its cloud features (if you’ve blocked the AcroCEF.exe file). You should see the connection failed error message. This confirms that you’ve successfully blocked Adobe Acrobat.
