What do I do if Windows 10 prevents installing an antivirus? 1. Turn off Windows Defender

Windows Defender is Microsoft’s built-in security tool, which protects your Windows 10 if you don’t have any other antivirus installed.

It shouldn’t make any problems with the third-party antivirus, but maybe some features of the antivirus conflict with Windows Defender, and that’s why you can’t install it.

So, try to turn off Windows Defender, and then install the third-party antivirus.

Now your Windows Defender is disabled, and you can try to install your antivirus program again.

2. Check if your antivirus is compatible with Windows 10

If you’re using some less famous antivirus, there’s a chance that it’s not compatible with Windows 10.

So, just in case, check out our list of all antivirus programs that are compatible with Windows 10, and if your antivirus is not on the list, you should consider getting a new protector of your system.

3. Make sure you don’t have any other antivirus installed

You should know that two antivirus programs don’t function well together, so if you already have some other antivirus installed, you should uninstall it before you try to install the new one.

There’s a chance that you didn’t even know that you have another antivirus on your computer, as it maybe came as a bloatware, along with another software you installed on purpose.

When Command Prompt starts, enter the following line, and press Enter: DISM /Online /Cleanup-Image /RestoreHealth

DISM scan will now start. This scan can take up to 20 minutes or more, so don’t interrupt it.

When the DISM scan is finished, check if the problem still persists. If the problem is still present, or if you were unable to run SFC scan before, try to run it again. After running SFC scan again, the issue should be resolved.

Third-party applications can interfere with your antivirus, and prevent you from installing it. If your Windows 10 prevents antivirus install, you might be able to fix the problem by performing a Clean boot.

This is rather simple and you can do it by following the steps above.

Although this is a useful feature, it can lead to certain issues. Speaking of issues, few users reported that this feature can prevent you from installing certain applications, such as your antivirus.
