Stop adobe acrobat from updating

At once I don't have acrobat, I thought it might be a virus and did scans with Avast and Malwarebytes, but they found nothing.

Important: A lot of software is updated regularly to fix security issues and you leave your system more vulnerable by not using the latest version.To disable update notifications, run the Adobe Application Manager and change the notification option. If you're running Windows 8 or a 64-bit version of Windows 7, navigate to C:\Program Files (x86)\Common Files\Adobe\OOBE\PDApp\core.If you're running a 32-bit version of Windows 7, navigate to C:\Program Files\Common Files\Adobe\OOBE\PDApp\core.Many popular applications these days have a built in function to update themselves automatically by downloading and installing new versions without asking or requiring user interaction.While auto updating is likely to be perfectly fine and a good idea for most users, it does become a problem if you are trying to troubleshoot instability with Windows or the specific application.
