What is NisSrv.exe?

NisSrv.exe is a legitimate executable file that is associated with Microsoft’s Windows Defender Antivirus. It is a crucial component of the Windows Defender program, which is designed to protect your computer from various types of malware, including viruses, spyware, and other malicious software.

Windows Defender is a built-in antivirus solution provided by Microsoft for Windows operating systems. It continuously monitors your system for potential threats and takes action to remove or quarantine any detected malware.

NisSrv.exe, also known as the “Windows Defender Network Inspection Service,” is responsible for performing network-based inspections of incoming and outgoing data on your computer. It helps identify and block potential threats by analyzing network traffic and comparing it against a database of known malware signatures.

Should I Remove NisSrv.exe?

As NisSrv.exe is a legitimate component of Windows Defender, it is generally not recommended to remove or disable it. Windows Defender plays a crucial role in protecting your computer from malware, and NisSrv.exe is an essential part of its functionality.

Disabling or removing NisSrv.exe may leave your computer vulnerable to various types of malware, as it won’t be able to perform network-based inspections and identify potential threats effectively.

However, there may be situations where you might consider disabling NisSrv.exe temporarily. For example, if you are experiencing performance issues or conflicts with other security software, you can try disabling NisSrv.exe and observe if the issues persist. If the problems are resolved, you can consider using an alternative antivirus solution or seek further assistance from Microsoft support.

If you decide to disable NisSrv.exe, follow these steps:

  1. Open the Windows Security app by clicking on the Windows Start button and searching for “Windows Security.”
  2. Click on “Virus & threat protection” in the left-hand menu.
  3. Under “Virus & threat protection settings,” click on “Manage settings.”
  4. Toggle off the “Real-time protection” option.

Keep in mind that disabling NisSrv.exe should only be done temporarily and with caution. It is recommended to re-enable it or use an alternative antivirus solution to ensure the ongoing protection of your computer.

Is NisSrv.exe Malware?

NisSrv.exe is not malware. It is a legitimate file associated with Windows Defender Antivirus. However, like any other executable file, it is possible for malware to disguise itself as NisSrv.exe to avoid detection.

We are huge fans of Malwarebytes Premium and use it on all of our devices, including Windows and Mac computers as well as our mobile devices.

    Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.

  3. Be careful when installing programs and apps.

    install guide

    Pay close attention to installation screens and license agreements when installing software. Custom or advanced installation options will often disclose any third-party software that is also being installed. Take great care in every stage of the process and make sure you know what it is you're agreeing to before you click "Next."

  4. Install an ad blocker.

    Ad Blocker

    Use a browser-based content blocker, like AdGuard. Content blockers help stop malicious ads, Trojans, phishing, and other undesirable content that an antivirus product alone may not stop.

  5. Be careful what you download.

    A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather.

  6. Be alert for people trying to trick you.

    Whether it's your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it's easy to spoof phone numbers, so a familiar name or number doesn't make messages more trustworthy.

  7. Back up your data.

    Back up your data frequently and check that your backup data can be restored. You can do this manually on an external HDD/USB stick, or automatically using backup software. This is also the best way to counter ransomware. Never connect the backup drive to a computer if you suspect that the computer is infected with malware.

  8. Choose strong passwords.

    Use strong and unique passwords for each of your accounts. Avoid using personal information or easily guessable words in your passwords. Enable two-factor authentication (2FA) on your accounts whenever possible.

  9. Be careful where you click.
