These days, people perform a variety of essential tasks and errands over the Internet. Technology has made it easier and convenient for us to pay our bills, communicate with people overseas, and shop for items that we need. However, if you learn about the various ways your computer can be hacked, you will definitely be alarmed. Needless to say, in today’s dangerous digital age, you wouldn’t use your PC without a reliable antivirus program.

System updates typically bring improvements and better features. However, many users have complained that Windows 10 stops antivirus installation processes. In most cases, third-party software should work fine with this operating system. On the other hand, it is possible for you to experience the following problems with installing antivirus software:

  • You’re unable to install antimalware or antivirus software on your Windows 10 computer. It is possible that the program is not compatible with your PC.
  • Malware or viruses might block the installation process. A rescue disk should be used on a different computer to get rid of the issue.
  • Corrupted files might be preventing you from installing your antivirus. This can be resolved by running SFC and DISM scans.
  • Third-party applications may also be blocking the installation process. In this case, removing such programs would fix the problem.

If you’re experiencing the aforementioned, don’t worry because we will teach you how to fix Windows 10 prevents antivirus issue. Just follow the methods below so you can get the protection that your computer needs.

Method 1: Remove other Antivirus Programs

Most antivirus programs work well with Windows Defender. However, if you have multiple third-party antivirus products installed on your computer, they might interfere with each other. It is also possible that you were not aware that you had installed the program in the first place. So, we recommend that you remove all other antivirus tools on your computer. With that said, follow the instructions below:

  1. Click the Search icon on the tray.
  2. Type “control panel” (no quotes), then hit Enter.
  3. Go to Programs, then click Programs and Features.
  4. Look for unwanted antivirus software.
  5. Right-click the program, then click Uninstall.
  6. Install the antivirus software you prefer.

We also advise you to choose an antivirus program that offers comprehensive features and yet compatible with Windows 10. With that said, opt for Auslogics Anti-Malware. This useful tool will protect your computer from malicious programs and files that may threat your personal data’s safety. What’s more, it won’t interfere with your built-in antivirus software.

Check your PC for malware to solve anti-virus installation issues,

Method 2: Disabling Windows Defender

As we’ve mentioned, Windows Defender should not be the reason behind your problems with installing antivirus software. On the other hand, your third-party security tool might have features that may come in conflict with Windows Defender. As such, we recommend turning off this built-in program first, then try installing your preferred antivirus program. Simply follow the instructions below:

  1. Go to the Search icon on the tray.
  2. Type “settings” (no quotes), then press Enter.
  3. Go to Update and Security.
  4. On the left bar menu, click Windows Defender.
  5. Click the Open Windows Defender Security Center button.
  6. Select Virus & Threat Protection.
  7. Scroll down, then click Virus & Threat Protection Settings.
  8. Turn off ‘Real-time protection.’

Disable Windows Defender to prevent its blocking the installation of your antivirus software.

Now that you’ve disabled Windows Defender, you can try installing your preferred antivirus software.

Method 3: Running an SFC scan

If Windows 10 stops antivirus installation processes, it is possible that there are corrupted system files in your computer. The good news is, there are many ways to fix this problem. One of the easiest ways to do so is to run an SFC scan. This program is specifically designed to repair corrupted system files. With that said, follow the steps below:

  9. Save the changes by clicking Apply and OK.
  10. Restart your computer, then check if the issue has been resolved.
  11. Once you’ve successfully installed your antivirus, enable all startup services and applications.

Method 5: Removing Junk and Temporary Files

Many users have reported that temporary and junk files are some of the reasons why the issue occurs. To resolve the problem, you have to remove these files. You can easily do this by using Disk Cleanup, which is a built-in Windows tool. This will let you remove unnecessary files and free up space on your hard drive. Simply follow the steps below:

  1. Click the Search icon on the taskbar.
  2. Type “disk cleanup” (no quotes), then hit Enter.
  3. Select the drive you wish to clean, then click OK.
  4. The program will calculate the amount of space that can be freed on your drive.
