Why is McAfee antivirus Not Working with Windows 10?

McAfee works great with the previous Windows versions, so when errors arise during its installation on a Windows 10 PC, there is a debate on which of the two tech giants is to blame. Indeed, the compatibility of McAfee with Windows 10 is quiet sensitive. 

A tiny detail missed during the installation can lead to failed protection and conflicts with other programs. The most common reasons of disrupted compatibility with McAfee with your Windows 10 device are: missing McAfee profile files, the installation of an incompatible McAfee version, and conflicts with other PC software.

1. Choose a Compatible McAfee Version

When working with McAfee, it’s important to know that it provides a wide selection of antivirus plans that suit specific devices. Choosing the wrong one will obviously trigger errors when trying to install the plan. Luckily, it’s quiet easy to find out whether your PC is compatible with the McAfee setup you have on hand. 

To do that, go to the antivirus setup requirements and check the RAM, processor and so on. Now, inspect the specifications of your device. If they don’t meet the McAfee requirements, the installation will fail. Return the existing setup and find one that matches your computer resources.

2. Transfer the License only on a Windows 10 Computer

One of the features of McAfee antivirus is transferring the license from one device to another. However, always make sure you transfer the license on the same platform as your previous device. That is, if your old PC ran on Windows, the license must be transferred on a Windows-operated device to be functionable.

3. Delete Any Conflicting Antivirus Programs

Sometimes, McAfee may conflict with a program on your device, which gives error when you least expect it. All you have to do is to remove the malicious program to breathe a new life into your antivirus. 

You can find the trouble-making program in the Apps folder. After identifying it, press Uninstall and delete the related files as well. Restart your PC and scan it with McAfee.

4. Get Rid of Junk Files

Junk files are an annoying trouble-maker that can compromise the operation of the antivirus on your Windows 10 computer or laptop. They are not of malicious nature, meaning they don’t harm your PC, but they can obstruct and confuse your McAfee security software.

Luckily, the error may be caused by a minor junk file as well, which you can effortlessly remove.

Junk files are temporary files, like cache, that your device uses during the installation of apps or performing other one-time actions. Once the command is done, the temp files lose their value and only occupy storage in your PC. Sometimes, they impede the antivirus to do its job. That’s why, make a point of deleting the junk files regularly to ensure no error messages pop up when scanning your device for malicious programs.
