What's New
🛡 Threat Actions
Scan results now include one-click quarantine and ignore for detected
threats. A dedicated threat card appears after each scan with batch
"Quarantine All" and "Ignore All" actions.
🔔 Notification System
Global MD3 Snackbar notifications slide in for all key events. System
tray toast notifications fire even when the window is minimized — you
will always know when a scan finishes.
📌 System Tray
Minimize to tray instead of closing. Right-click the tray icon for a
quick-scan shortcut or to exit. Left-click or double-click restores
the window.
🎨 Dark & Light Themes
Choose between System (follows your Windows theme), Light, or Dark
mode from the Settings page. The entire UI updates in real time
without restarting.
📋 Changelog Popup
A changelog dialog greets you on the first run after each update.
Revisit it anytime from the About section in Settings.

Only one copy of Zack Defender can run at a time. Attempting to open
a second instance shows a friendly notice and exits.
🖼 Updated Icon
Fresh new app and tray icon.
