Windows Security Center reporting 'at-a-glance' issues

The Windows Security Center prompts "clear at a glance" problem is usually not a virus or system crash, but an exception in security settings. 1. Antivirus protection is not enabled: Defender is not restarted after uninstalling the third-party antivirus software. The solution is to manually enable real-time protection or reset Defender; 2. The firewall is turned off: Check the firewall status and ensure it is turned on. If it cannot be changed, you need to check the group policy or registry; 3. Device security is disabled: Turn on virtualization technology in the BIOS and enable kernel isolation; 4. Third-party software interference: Clean up residual processes and ensure that Microsoft security services are set to automatically start. Troubleshooting these settings can solve the problem in most cases.

A "clear" question prompt suddenly popped up in the Windows Security Center. Many people's first reaction was: "What happened to my computer?" In fact, this situation does not necessarily mean that you are infected with a virus or the system crashes. Most of the time, some security settings are not in place or the functions are turned off. The most common ones are abnormal statuses such as antivirus, firewall, and device security.

Let’s talk about why this happens from several common perspectives and how you can deal with it.

Antivirus protection is not enabled or expired

Windows Defender is an antivirus program that comes with Windows. If you install third-party antivirus software (such as Kaspersky, Turf, 360), it may be automatically deactivated. But once you uninstall these software and do not manually restart Defender, the Windows Security Center will report "Anti-virus protection is not enabled".

Solution:

• Open Settings → "Privacy and Security" → "Windows Security Center" → "Virus Protection"
• Check if real-time protection is enabled
• If you see "protected by other applications" but you do not install any antivirus software, it may be caused by residual configuration. You can try resetting Defender or running system file checker (sfc /scannow)

Firewall or network protection is turned off

Sometimes you temporarily turn off the firewall while debugging certain programs, and later forget to turn on it, or turn off the network protection function by mistake. In this case, the Security Center will also prompt a "clear" problem.

Inspection method:

• Go to "Windows Security Center" → "Firewall and Network Protection"
• Check whether the firewall status under the current network type (public/private) is "Open"
• If it is a gray-in-unchangeable state, it may be a problem with Group Policy restrictions or registry settings.

Device security or kernel isolation is disabled

This function is generally enabled by default, but it will be automatically turned off in some old computers or specific driver environments. If you see "Device Security" display "Unsecure", this usually means your system lacks hardware-level security protection (such as virtualization technology VT-x not enabled).

You can try:

• Confirm whether virtualization technology is enabled in BIOS/UEFI
• Return to "Windows Security Center" → "Device Security" → Turn on "Kernel Isolation"
• If the prompt cannot be turned on, you may need to update the driver or firmware

Third-party software interference security services

Some optimization tools (such as one-click acceleration and cleaning software) will shut down the system background services without authorization to "improve performance", and as a result, Windows security-related services are also stopped. This kind of situation is common on machines with more unofficial software.

Suggested practices:

• Check whether there are any third-party security software residual processes
• Use Task Manager to view the Startup tab to see if Microsoft services are disabled
• If you are not sure which services should be opened, you can find Security Center-related services in the Services Manager, set it to "Auto" and restart it

When the "at-a-glance issues" prompt appears, don't rush to doubt whether it is poisoned. First check it in the above directions. Most of the time, it is just a certain setting that has been changed or caused by software conflicts. It is not complicated to repair, but it is easy to ignore details, such as BIOS settings and service status. You can do it with a little more patience.

Basically that's it.
