Can You Run Avast and Windows Defender Together? [2022]

If you want to ask the question of running both Avast and Windows Defender Together?

The answer is simple yes, they will get along just fine. It’s a good idea to supplement Windows Defender with a good third-party antivirus program, such as Avast. But, You do not require both on your system. You only need one antivirus program.

To avoid conflicts, no matter which third-party (non-Microsoft) antivirus application you use, it will always turn off Windows Defender.

In response to your question, “Will it cause a conflict between Defender and Avast running concurrently?” The answer is Yes.

How To Disable Avast and Enable Windows Defender?

Doing so may completely disable your system’s antivirus protection, so only do it if you intend to install any other such software.

Here’s how to altogether disable Avast Antivirus without deleting the app. Following that, instructions for enabling Windows Defender are provided below.

  • Step 1: Locate the orange Avast icon on the Windows taskbar, then right-click to open the Avast antivirus settings.
  • Step 2: Navigate to Avast Shields and select one of the available options, such as disabling for 10 minutes, an hour, until the computer is restarted or permanently disabling the shields.
  • Step 3: Confirm the selected option by clicking “OK,” and all shields will be paused for however long you have specified.
  • Step 4: Return to the antivirus’s main window to confirm that Avast has indeed disabled all of the shields. Now, stay on the status tab and wait for the prompt below.

If you get the above prompt, you’ve successfully disabled all the shields.
If you need to restart the shields, click the ‘TURN ON’ option in the main window, and your shields should be back on.

Now that you have disabled Avast and you want to enable Microsoft Defender Antivirus. To activate Microsoft Defender Antivirus on your device, follow the steps below.

  • Choose the Start menu.
  • Enter group policy in the search bar.
  • Then, from the list of options, choose Edit group policy. The Local Group Policy Editor window will appear.
  • Choose Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender Antivirus from the drop-down menu.
  • Select Turn off Microsoft Defender Antivirus at the bottom of the list.
  • Disabled or Not configured are the options. Selecting these options may seem counterintuitive because the names imply turning off Microsoft Defender Antivirus. Don’t worry; these options ensure that it is turned on.
  • Choose Apply > OK.

Why is Windows Defender Blocking Avast?

You should run only one antivirus application at a time. Running multiples can cause conflicts between them. This will also put an unnecessary load on your system (processing-wise).

Aside from Avast free antivirus, which is available as a free antivirus solution, Avast offers many other versions (all of which are paid) that are loaded with features that provide comprehensive malware protection.

In most cases, when you onboard your devices to Defender for Endpoint, you can use Microsoft Defender Antivirus alongside your non-Microsoft antivirus solution for added protection.

For example, you can use EDR in block mode, which blocks and remediates malicious artifacts that your primary antivirus solution might have missed.

Will installing Avast disable Windows Defender?

Yes, Avast antivirus has a recurring problem in which one of its executables (visthaux.exe) is blocked from running by Windows Defender. “Your organization used Windows Defender Application Control to block this app,” says the error message.

After further investigation, it appears that the problem is unique to Windows 10 and only occurs on Technical Preview and Insider builds. 

Insider builds, and technical previews are not thoroughly tested and frequently cause a slew of unexpected issues.

As a result, using third-party antivirus software with Insider and Pre-Release builds is less than ideal.

The instability of many Insider builds causes this problem. If you want to avoid these issues, you should discontinue the Insider program and instead use the most recent stable Windows 10 build.

If your third-party Avast antivirus is being blocked by the built-in Windows Defender antivirus, there are a few solutions you can try. Below are a few fixes that users in a similar situation have used to correct this behaviour.

One of the ways to stop it is by turning off Defender’s shields. Then you should restart your computer and run avast again, and it will work.

Turn Defender’s shields back on, and it will work completely fine. Just make sure to turn off all antivirus and firewall stuff in Defender.

Do I Need Avast If I Have Defender?

AV-comparison tests were conducted, and the results revealed that while Windows Defender detected 99.5 percent of malware, Avast anti-virus detected 100 percent of malware.

Avast also has a slew of advanced features that Windows Defender lacks. These are the reasons why Avast easily outperforms Windows Defender.

Windows Defender is well-known for providing basic malware and virus protection. For users who spend a lot of time on the internet and have a lot of essential data on their computer, it’s best to go with anti-virus software like Avast, which has many advanced features.

Avast is an anti-virus solution available for Windows, Android, and Mac operating systems. It was created by Avast Software and is freely available to users who want to use it for personal purposes.

It is a myth that free anti-virus solutions do not provide end-to-end protection and can only be used as a stop-gap measure.

One solution that dispels this myth is Avast. With a plethora of features at its disposal, it can compete head-to-head with many of its paid competitors.
