Apps by system

Official stores only. A WhatsApp antivirus is the scam.

Windows

Microsoft Defender · Bitdefender · Malwarebytes (scan) · Firefox + uBlock Origin · Privacy Badger · Brave · NextDNS / AdGuard DNS · GlassWire · Fing Desktop · Bitwarden. Do not stack three banner AVs.

iPhone

Keep iOS updated. AdGuard / 1Blocker / Wipr · Brave · system DNS · Fing · iCloud Keychain or Bitwarden. uBlock does not exist on iOS.
