How to stop Adobe Acrobat Reader from being updated via the internet in the background:

1. Use a third-party firewall: If you're having trouble configuring your built-in firewall, you might want to consider using a third-party firewall software that comes with more advanced features and is easier to configure. Some popular options include Norton Firewall, ZoneAlarm, and Comodo Firewall.

2. Disable automatic updates: If you don't want Adobe Acrobat Reader to update automatically in the background, you can disable this feature by following these steps:

   - Open Adobe Acrobat Reader

   - Go to Edit > Preferences

   - Select Updater from the left-hand menu

   - Under the section "Automatically install updates," select "Do not download or install updates automatically"

   - Click OK to save your changes

3. Block Adobe update servers: If you want to be absolutely sure that Adobe Acrobat Reader is not updated via the internet in the background, you can block Adobe's update servers using your firewall. To do this, you'll need to create a new rule in your firewall settings that blocks traffic to and from the following servers:

   - swupmf.adobe.com

   - swupdl.adobe.com

   - lm.licenses.adobe.com

By blocking these servers, you'll prevent Adobe Acrobat Reader from being able to check for updates or download updates in the background.
