It can be very annoying when people’s computers are running Windows 11 or 10, and McAfee not working or won’t open or start. This problem could be caused by a number of things, including expired certificates, malware attacks, damaged McAfee files, or issues with the McAfee driver check tool. In the event that McAfee identifies a certificate that has expired, the software may become inoperable, which will result in the inability to launch or launch the programme.

Most of the time, McAfee won’t open because:

Expired Certificate

Some versions of McAfee Live Safe or Total Protection have expired certificates, causing the software to stop working when detecting the expired certificate.

Malware Infection

Presence of viruses or malware on the PC can prevent McAfee from opening. This is because malware can disable or modify the antivirus software, making it unable to function properly. In such cases, the first step would be to run a full scan with McAfee to detect and remove any malicious programs on the system.

Damaged or Corrupt Files

Installed McAfee files may become damaged or corrupted, hindering the software from starting. This can occur for various reasons, such as a virus or malware attack, system errors, or incomplete updates.

In these situations, it is important to troubleshoot the issue and repair any damaged or corrupt files.

Battery Check Issue

Problems with the McAfee battery check feature can also contribute to the software not opening. If your device’s battery is running low, this can cause issues when attempting to open McAfee. Because executing the software could further drain the remaining energy. The battery check feature is meant to stop the software from opening if the device’s battery drops below a specific point.

Ways to Fix McAfee Not Loading Problem:

1. Restart PC: Sometimes, a simple restart can resolve temporary glitches or errors in the system that may be causing McAfee to not work properly. To do this, simply click on the “Start” button and select “Restart.” Once your computer has restarted, try opening McAfee again.

2. Run AV Scan: Running a full antivirus scan can help identify and remove any malicious files or viruses that may be interfering with McAfee’s functioning. Open the McAfee software and click on the “Scan” tab to initiate a scan of your system.

3. Verify McAfee Installation: Errors in the operation of the McAfee software could potentially result from improper installation on your computer. In order to validate this assertion, navigate to the Control Panel and examine whether McAfee is categorised under “Programmes” or “Programmes and Features.” If not, reinstallation might be necessary.

4. Run McAfee TechCheck Utility: The McAfee TechCheck Utility is a tool designed to diagnose and fix common issues with the program. It can help identify any underlying problems that may be causing McAfee to not work properly. To use this tool, go to the official McAfee website, download and run it on your computer.

5. Check and Resolve Battery Check Issue: If you are using a laptop, it is possible that the battery check feature in McAfee may be causing issues with the program’s functioning. To resolve this, go to “Settings” in McAfee and disable the battery check option.

6. Reinstall McAfee: If none of the above steps work, it may be necessary to reinstall McAfee on your computer. To do this, go to the Control Panel, select McAfee from the list of installed programs and click on “Uninstall.” Then, go to the official McAfee website and download the latest version of the software to reinstall it on your computer.

Windows Defender Conflict
