Why Does Windows Firewall Keep Turning Itself On? | Cpugpunerds.com

Windows Firewall is an outstanding feature of the Windows operating system to protect your computer from network-based threats.

Threats include DoS attacks, hacking, virus attacks, scamming, etc. Firewall does this by blocking unauthorized traffic from other devices to your computer and vice versa. By traffic, we mean the data that unauthorized computers try to send to your computer. Such data can contain viruses or ransomware etc.

It can also be software that shares your computer screen without your permission with the attackers. It lets them see and record your personal information and credentials, such as your bank account or debit card details. This article discusses “Why does Windows Firewall keep turning itself on?”

Why Does Windows Firewall Keep Turning Itself On?

It keeps turning on when your computer is under attack. It can be a virus executing in the background or malware trying to reach your computer through the Internet. In both cases, the Windows Defender will try to turn on your Firewall, especially when you have disabled it intentionally.

There can be different reasons behind this issue:

  • Windows Updates
    Windows Firewall turns on automatically during updates. It is because, during the updates, your operating system has to download files from the Internet. Unwanted files can be downloaded during this if the Firewall is disabled. Windows turns it on to protect your precious data, apps, and computer.
  • An Online Virus Attack
    If you have disabled your Windows Defender and it is repeatedly asking you to turn it on, your computer system may be under an online virus attack. You should never ignore such messages from your Firewall and respond to them as soon as possible. Otherwise, you can suffer severe data loss.
    The Internet is full of websites that contain viruses, especially the ones that offer cracked video games. That is why nearly all web browsers scan your downloading files to protect your precious data and apps. But all apps do not have this amazing feature, and sometimes we force them to download our files.
    As a result, a computer comes under a virus attack. It starts downloading and saving viruses on your storage media such as HDD or SSD. During this attack, your Windows Defender turns on the Firewall to stop this virus from downloading and storing on your storage device to protect your device, data, and apps.
  • Virus Executing In The Background
    Sometimes we download and install viruses on our computers unknowingly. It happens either when the Windows Defender and its Firewall are disabled or when we forcefully download the files despite the warning about being a harmful file. All well-known web browsers warn us about files containing viruses.
    Such malware downloads and installs automatically without our notice. After this, it starts running in the background whenever you start your computer or open a certain app or game. To stop its execution, the Windows Firewall keeps turning on to protect your precious data and priceless application software.
  • A Hacker Trying To Reach Your Computer
    When hackers and attackers try to do so, they try to disable your Firewall first. It is because Windows Defender is the only largest hurdle in their way to access your computer system. First, they can’t disable it as it is a powerful app. But mostly, we provide them easy access by disabling it.
    Hence, when hackers try to access your computer or its certain resources, and your operating system detects it, it keeps turning on its Defender’s Firewall. As a result, you see a message about this phenomenon. In this case, don’t hesitate if the Windows Defender has detected a virus that needs to be removed.
  • Your Privacy Being Compromised
    Each computer has a unique identity which is known as its MAC address. It has another identity called an IP address for communicating through the Internet. Both of these addresses tell a hacker or attacker about the computer user. Your Firewall may be doing so so you can stop the attack.
    Mostly, Windows operating systems use DHCP to hide your identity over the Internet. Despite that, cybercriminals can track you because your web browsers have plenty of information about you. This information includes your email id, cookies-related interests, first and last name, debit card details, etc.
  • A Spyware
    Most naive computer users install unknown software running in the background whenever they switch on their computers. Most of such software is spyware. Spywares secretly sends detailed stats of your daily activities to cybercriminals, including screenshots and recordings.
    In this case, your operating system detects the spyware and turns on the Firewall, warning you. It also warns you to turn on the Firewall if it is disabled. You must take some action, as most computer users type passwords without hiding them. Every feature has a purpose, so we must use it properly.
    You can lose your money if it is your bank account details that you are using to login and transfer money from one account to another. Criminals have no mercy when stealing from you. They try to withdraw as much money as possible, leaving the account 100% empty. It can be your years-old savings.
  • Permissions To Certain Games & Apps
    Some games and apps ask you to allow them public network access through the Windows Firewall. Without this, you cannot use or play them and use their online features. Hence, your Firewall turns on whenever you open that app or game. And every time Windows Defender shows you the message from your Firewall.

Turning off the Windows Defender is not recommended because it protects your computer from all threats, including hacking. Turning it off gives cybercriminals access to your computer and privacy. It lets you accidentally download and install viruses and spyware, compromising your data and money.


Windows Firewall can automatically turn on during Windows updates. It does so to prevent any unauthorized files from downloading on your computer. An ongoing online virus attack can also trigger your operating system’s Firewall. A virus running in the background can also be a reason behind this issue.

It can be a cybercriminal, a hacker, or an attacker trying to reach your computer for complete access. It can also be ransomware running in the background. Spyware can also be the culprit behind this phenomenon, as these software keep track of your daily activities.

In the worst case, someone has access to your computer screen, and he might be watching your screen just like you. That is why you should never install software from unknown publishers. It can be an app or game that activates the Firewall every time you run it. You must permit it at least once.

You should never turn off your Firewall or the Windows Defender, as it can result in severe data loss. It can also result in the loss of a reasonable amount of money if the hackers have all your bank account or debit card details. That’s why turning them on or installing an antivirus is the best option.
