When and why you might need to disable antivirus
You may need to turn off your antivirus temporarily when installing software that your antivirus blocks by mistake, when troubleshooting a problem, or when a legitimate program needs access your antivirus is preventing. The key word is temporarily — you should re-enable it as soon as you finish what you're doing.
Antivirus software sometimes flags safe programs as threats because the program's behavior looks suspicious to the scanning engine, even though it's harmless. Other times, an antivirus setting is too strict and blocks a program you actually want to use. Disabling it briefly lets you test whether the antivirus is the cause of the problem.
Never disable your antivirus and then browse the internet, download files, or open email attachments. That's when you're most vulnerable to actual malware. Disable it only for the specific task you need to do, then turn it back on immediately.
Key Takeaways
- Disable your antivirus only for the specific task you need to complete, then re-enable it right away — do not leave it off while browsing or downloading.
- Windows Defender (built into Windows) disables itself temporarily through Settings, while third-party antivirus programs like Norton or McAfee have their own control panels.
- Some antivirus programs offer a "pause protection" option that disables the software for a set time period, then automatically turns itself back on.
- If you cannot find how to disable your antivirus, check the program's help menu or search the vendor's website for your specific version.
How to disable Windows Defender on Windows 10 and 11
Windows Defender is the antivirus that comes built into Windows. To turn it off temporarily, open Settings by pressing the Windows key and typing "Settings," then click the Settings app that appears.
Once Settings is open, click Privacy & security in the left sidebar. Then click Windows Security. Next, click Virus & threat protection. You'll see a section labeled "Virus & threat protection settings" — click the link that says Manage settings.
You'll see a toggle switch next to "Real-time protection." Click it once to turn it off. Windows will ask you to confirm — click Yes. Real-time protection is now disabled. Do what you need to do, then come back to this same screen and click the toggle again to turn it back on.
If you see a message saying you don't have permission to change this setting, your computer is managed by an organization (like your workplace or school) and you cannot disable Windows Defender yourself.
How to disable third-party antivirus programs
If you installed Norton, McAfee, Kaspersky, Bitdefender, or another antivirus program yourself, the steps are different for each one. Look for the antivirus icon in your system tray — this is the small area at the bottom right of your screen where the clock is. Right-click the antivirus icon and look for an option that says "Disable," "Pause," "Turn off," or "Exit."
If you don't see the icon in the system tray, open the antivirus program itself by clicking its icon on your desktop or searching for it in the Start menu. Once the program is open, look for a menu or settings button — this is often three horizontal lines, a gear icon, or a button labeled "Menu." Click it and search for options like "Disable protection," "Pause scanning," or "Turn off real-time protection."
Some programs, like Norton, offer a "Pause protection" button that lets you choose how long to disable the antivirus — 15 minutes, 1 hour, or until you restart your computer. This is safer than manually turning it off and forgetting to turn it back on, because the program will re-enable itself automatically.
If you cannot find the disable option in your antivirus program, visit the vendor's website and search for "[Program name] how to disable" or "[Program name] pause protection." Each vendor's website has instructions for their specific version.
How to disable antivirus on Mac
If your Mac has a third-party antivirus like Norton or McAfee, open the program and look for a menu or settings option. Most Mac antivirus programs have a button or menu item that says "Turn off protection," "Disable scanning," or "Pause." Click it and choose how long you want the antivirus disabled.
Mac computers do not have a built-in antivirus like Windows Defender. If you're using only the built-in security features (which most Mac users do), there is nothing to disable. macOS handles security through its built-in protections, and you cannot turn those off without using Terminal commands that require administrator knowledge.
If you're unsure whether your Mac has a third-party antivirus, look in your Applications folder. Open Finder, click Applications in the sidebar, and scroll through the list. If you see Norton, McAfee, Kaspersky, or another antivirus program, that's what you have installed.
What to do if your antivirus won't disable
Some antivirus programs are locked by an administrator and cannot be disabled without a password. This is common on work computers, school computers, or computers managed by an organization. If you see a message saying you don't have permission to disable the antivirus, you'll need to contact your IT department or the person who manages your computer.
If you own the computer and set it up yourself, but you still cannot disable the antivirus, try restarting your computer in Safe Mode. Safe Mode starts Windows with only the essential programs running, which sometimes allows you to disable antivirus software that won't turn off normally. Search online for "Safe Mode [your Windows version]" to find the steps for your specific version of Windows.
Another option is to uninstall the antivirus program entirely if you no longer want it. Go to Settings, click Apps, then Apps & features, find your antivirus in the list, click it, and click Uninstall. Be aware that uninstalling leaves your computer without antivirus protection until you install a different one.
Re-enabling your antivirus after you're done
After you finish the task that required disabling your antivirus, turn the protection back on immediately. Go back to the same screen where you disabled it and click the toggle or button to turn it back on. If you used the "Pause" feature, your antivirus will re-enable itself automatically after the time period you chose.
Once your antivirus is back on, run a quick scan to make sure nothing harmful got onto your computer while protection was off. In Windows Defender, open Windows Security, click Virus & threat protection, and click Quick scan. In third-party programs, look for a "Scan" or "Quick scan" button in the main window.
If the scan finds anything, your antivirus will tell you what it found and ask what you want to do. Let it remove or quarantine the threat. If you're unsure what the threat is, search for it online or contact the antivirus vendor's support team.
Frequently Asked Questions
Can I disable my antivirus while I'm downloading something?
No. Disabling your antivirus while downloading is the most common way people get malware. Only disable it for tasks that don't involve downloading, opening email, or browsing the internet. If you need to download a file and your antivirus is blocking it, disable the antivirus, download the file, then re-enable it and scan the file before opening it.
Will my computer get a virus if I disable my antivirus for 10 minutes?
Not necessarily, but the risk is real. Malware can infect your computer in seconds if you visit a dangerous website or open a malicious file. The longer your antivirus is off, the higher the risk. Keep it disabled for only as long as you need — usually just a few minutes.
Why does my antivirus keep turning back on after I disable it?
Some antivirus programs are set to re-enable automatically after a certain time period for security reasons. Check your antivirus settings to see if there's an option to change how long it stays disabled. If your computer is managed by an organization, the antivirus may be forced to stay on and cannot be disabled at all.
Is it safe to leave my antivirus disabled overnight?
No. Leaving your antivirus off overnight is dangerous because malware can infect your computer while you're not watching. Only disable it for the specific task you need to do, then turn it back on. If you forget to re-enable it, restart your computer — this will usually turn your antivirus back on automatically.
What if I disabled my antivirus and now my computer is running slowly?
Turn your antivirus back on and run a full scan. Slow performance after disabling antivirus often means malware got onto your computer while protection was off. A full scan can take 30 minutes to several hours depending on how much data you have, but it will find and remove threats. If the scan finds nothing and your computer is still slow, restart your computer and check again.
