An unavailable Internet Security switch usually means that the license, operating system, update state, or network-filter component is not ready. Work through these checks in order.
1. Confirm the license
Open Info and confirm that the app reports an active license or eligible trial. If the license recently changed, restart the app and Windows. Follow the activation guide if the status is inactive.
2. Update the app and Threat List
Open Update, check for both application and Threat List updates, and restart when prompted. Real-time web protection should not be enabled with stale protection data.
3. Check Windows compatibility
The current product requires a supported Windows installation. Windows XP and Vista are not supported, and legacy Windows releases can lack the components or security updates required by the network filter. Review the current system requirements.
4. Check conflicts and repair the filter
- Restart Windows after installation or a major app update.
- Check whether another antivirus, web filter, VPN, company policy, or network-control product is blocking the Gridinsoft component.
- Do not remove a corporate filter without administrator approval.
- If the switch remains unavailable, run the current official installer as administrator to repair the installation, then restart.
Before contacting Support
Collect the Windows version, Gridinsoft version, license status, update status, and a screenshot of the disabled switch. Then send a support request. Keep another supported web-protection layer active while Internet Security is unavailable.
