  1. To go to Safari Preferences, the keyboard shortcut for Mac is Cmd + , or Ctrl + , for PC.

  2. Thank you so very much for this information, especially the step to look in ~/Library/LaunchAgents and /Library/LaunchAgents. I found updaters in the first location (but not the second). Having this malware fix was HUGELY helpful. Merely removing the directory ~/Library/Application Support/ProntoApp would have only lasted about 13 hours. THANK YOU! THANK YOU!
