nfsCalendar04

nfsCalendar04 is a malicious or spam-based calendar subscription commonly associated with the “calendar virus” scam. It is not an actual device-encrypting virus or a piece of executable malware; rather, it is a rogue, third-party calendar that tricks you into subscribing to it. Once added, it floods your device’s calendar app with urgent, spam-filled notifications containing dangerous phishing links. How It Got on Your Device

You likely encountered this while browsing a third-party streaming site, download portal, or adult website. These sites trick users by displaying fake “I am not a robot” CAPTCHAs or system warning pop-ups. Tapping anywhere on those deceptive pages triggers a prompt asking you to subscribe to a calendar. If you tap “OK” or “Allow” to bypass the prompt, the subscription becomes active. The Risks Involved

Phishing Alerts: The calendar generates hourly or daily events with alarming titles (e.g., “Your device is infected!”, “Click to secure your data!”, or “Package waiting for delivery!”).

Malicious Links: Tapping the links hidden inside these calendar descriptions will redirect you to phishing sites designed to steal credentials, display aggressive adware, or trick you into downloading real info-stealing malware. How to Remove It Immediately

Do not click any links or interact with the event notifications. Follow these platform-specific steps to completely remove the calendar from your device: 4-5-4 Calendar – National Retail Federation | NRF
