Antivirus software is a program that runs on your computer to protect it from harmful files and malicious code. Think of it as a security guard for your device. It constantly scans files, programs, and websites you visit to identify anything that might damage your system or steal your personal information. According to the 2023 Internet Crime Complaint Center report, cybercriminals launched over 880 million malware attacks globally that year, making antivirus protection an important consideration for most computer users.

Your antivirus software works in multiple ways. It uses a database of known threats—patterns of malicious code it recognizes—to spot dangerous files. It also monitors how programs behave on your system, watching for suspicious activity that might indicate a new or unknown threat. Real-time scanning means the software checks files as you download them, open them, or access them from storage devices. Many antivirus programs also include a firewall, which controls what information enters and leaves your computer through your internet connection.
Most operating systems come with built-in antivirus features. Windows includes Windows Defender, and Mac systems have XProtect. Many users also choose to add third-party antivirus software from companies like Norton, McAfee, Kaspersky, or AVG for additional layers of protection. These programs typically run continuously in the background, using system resources to perform their scanning and monitoring functions.
Practical takeaway: Before turning off any antivirus software, understand what protection it provides so you can make an informed decision about whether you need alternative protections in place.
People turn off antivirus software for several legitimate reasons. The most common reason is system performance. Antivirus programs consume processing power and memory, which can slow down older computers or those with limited resources. A 2022 study by independent testing organization AV-TEST found that some antivirus programs could reduce system speed by 15-20 percent during intensive scanning operations. Users with computers that have smaller hard drives or less RAM may notice their system becoming sluggish when multiple programs run simultaneously.

Another reason involves software conflicts. Sometimes antivirus programs interfere with other software you're trying to run. Game developers, for example, often report that antivirus software flags gaming files as suspicious because the programs use unusual system access methods. Antivirus software might prevent certain legitimate programs from installing or running properly, blocking files it incorrectly identifies as threats. Some users working with specialized software for video editing, coding, or design work disable their antivirus temporarily to eliminate interference.
Technical support or troubleshooting is another common scenario. When you're trying to diagnose why a computer is malfunctioning, tech support specialists sometimes recommend temporarily disabling antivirus software to determine whether the antivirus itself is causing the problem. This helps narrow down whether issues originate from the antivirus program or from something else on the system.
Some users also disable antivirus software when working with files they trust completely, such as programs they've written themselves or files received from trusted sources they've manually verified. Others disable it temporarily while performing maintenance tasks on their system that they believe might trigger false alarms.
Practical takeaway: Understanding your specific reason for wanting to turn off antivirus software helps you decide whether you need a temporary or permanent solution and what alternative protections you should consider.
The process for disabling antivirus software on Windows depends on which antivirus program you're using. For Windows Defender, which comes built into Windows 10 and 11, you access the settings through the Windows Security application. Open Windows Security by clicking the shield icon in your system tray or by searching "Windows Security" in your start menu. Once open, click "Virus & threat protection" in the left sidebar. You'll see an option labeled "Manage settings" under the Virus & threat protection settings section. Click this option, and you'll find a toggle switch for "Real-time protection." You can turn this switch off to disable active scanning.

For third-party antivirus software like Norton, McAfee, or Kaspersky, look for the program in your system tray—usually a small icon in the bottom right corner of your screen. Right-clicking this icon typically opens a menu with options to turn off or disable protection. Alternatively, open the full antivirus program by double-clicking its desktop icon or finding it through your Start menu. Once inside the program, look for settings or preferences, usually accessible through a menu or gear icon. Within settings, you'll typically find an option to disable protection, turn off real-time scanning, or pause the program.
Some antivirus programs offer different levels of disabling. You might see options to "pause protection" for a set amount of time (like 30 minutes or one hour), which automatically re-enables protection after that period. This is safer than permanently turning off your antivirus. Other programs let you disable specific features, like real-time scanning or firewall protection, while keeping other protective features active.
Important note: In Windows 10 and 11, if you disable Windows Defender and don't have another antivirus program running, Windows will show you notifications reminding you that your system isn't protected. These notifications appear periodically to encourage you to re-enable protection.
Practical takeaway: Most antivirus programs offer options to pause or disable protection temporarily rather than permanently turn it off, which provides a balance between eliminating interference and maintaining some protection.
Mac computers have different antivirus considerations than Windows machines. Apple's built-in security features include XProtect, which scans files for known malware, and Gatekeeper, which verifies that applications come from trusted sources. These features are integrated into the operating system and cannot be completely disabled in the traditional sense. However, you can adjust how strictly these security features operate.

To modify macOS security settings, click the Apple menu in the top-left corner and select "System Preferences" or "System Settings" depending on your macOS version. Navigate to "Security & Privacy" or "Privacy & Security." In the "General" tab, you'll see options related to allowing applications from different sources. By default, macOS restricts installation to applications from the App Store and identified developers. If you change this setting, you're loosening the restrictions, though you're not actually turning off security—you're just reducing how strictly macOS enforces it.
If you've installed third-party antivirus software on your Mac from companies like Norton, Kaspersky, or Bitdefender, disabling it works similarly to Windows. Open the antivirus program, look for preferences or settings, and find the option to disable or pause real-time protection. Many Mac antivirus programs have an icon in the menu bar at the top of your screen. Clicking this icon often reveals options to pause or disable protection temporarily.
Unlike Windows, macOS doesn't display warning notifications if you disable antivirus protection. Apple's approach assumes that users understand their security settings and deliberately made changes. The operating system itself, however, continues running XProtect in the background regardless of third-party software status.
Note: If you're running an older version of macOS and want to adjust XProtect more directly, you would need to access Terminal, which requires advanced technical knowledge. Most typical Mac users won't need to do this.
Practical takeaway: On Mac, complete antivirus disabling is more complex than on Windows because security features are integrated into the operating system itself. Most adjustments involve loosening restrictions rather than turning off protections entirely.
Turning off antivirus software exposes your computer to significant security risks. When antivirus protection is disabled, your system can be infected with malware—software designed to damage your computer, steal your data, or use your system to attack others. The scope of this risk is substantial. According to Statista, in 2023, there were approximately 560,000 new malware variants detected every single day. Without antivirus protection, your computer becomes vulnerable to any of these threats.
