Which Modern Methods app is right for you?
Choose Sentinel AI when your question is about what is happening on a Windows PC: suspicious behavior, system evidence, quarantine, or remediation. It works alongside Microsoft Defender rather than replacing the Windows antivirus engine. Start with the Sentinel AI overview or read how it compares with Defender.
Choose Decide For Us when the challenge is deciding what to do. It is designed around two practical options rather than a sprawling list. Explore the app overview, date night decision guide, or support center.
