Sophos Endpoint Security and Control: removal of third-party security software prompts user for input

Issue
Certain old versions of Symantec LiveUpdate require user input to complete removal.

During a deployment of Sophos Endpoint Security and Control to endpoints with these old versions installed, where the uninstallation of update tools is enabled in the configuration of the Competitor Removal Tool, a prompt to approve or decline the removal of LiveUpdate will appear.

Identified versions include Symantec LiveUpdate 1.3 and 1.4, commonly installed as part of Norton Antivirus 7.0 or earlier. Norton Antivirus or Symantec Antivirus 8.0 or later do not exhibit this behaviour and LiveUpdate is uninstalled without any prompts.
