  • Each has a real cost: Avast One ransomware and Wi-Fi vulnerability protection only on paid plans; Signal signal must be installed on a phone before the desktop app can be used, so there is no phone-free desktop-only account
  • They diverge on capability: Avast One covers Antivirus, Signal covers End-to-end encryption.
