Why you might need to disable McAfee temporarily

You may need to turn off McAfee antivirus for a few specific reasons: installing software that McAfee blocks incorrectly, troubleshooting a problem with another program, or testing whether McAfee itself is causing a slowdown. Disabling it is different from uninstalling it — the software stays on your computer but stops actively scanning and protecting until you turn it back on.

Before you disable McAfee, understand that your computer will be unprotected while it is off. Do this only when you are actively working on the task that requires it, then turn protection back on when ready after. Never leave antivirus disabled for hours or days.

Key Takeaways

  • McAfee can be paused from the main window for 15 minutes, one hour, or until you restart your computer — the fastest temporary option.
  • Full disabling requires opening Settings, finding the Real-Time Scanning toggle, and turning it off, which leaves your computer unprotected until you reverse it.
  • If McAfee is blocking a legitimate program, you can add that program to the exclusions list instead of disabling the entire antivirus.
  • Some versions of McAfee require administrator access to change these settings, so you may need to right-click and select "Run as Administrator."
  • Restarting your computer automatically re-enables McAfee protection, so you do not have to remember to turn it back on manually.

Pausing McAfee for a short time

The quickest way to stop McAfee from interfering is to pause it rather than disable it completely. Open the McAfee window on your taskbar or from your Start menu. Look for a button labeled "Pause" or a shield icon with a pause symbol.

Click that button and McAfee will ask you how long to pause protection: 15 minutes, one hour, or until you restart your computer. Choose the option that matches how long you need — if you are installing a single program, 15 minutes is usually enough. McAfee will automatically resume after the time runs out, so you do not have to remember to turn it back on.

Fully disabling Real-Time Scanning

If pausing is not enough and you need to turn off McAfee completely, you will disable Real-Time Scanning. Open McAfee and look for a settings or gear icon, usually in the top right corner of the window. Click it and select "Settings" or "Preferences."

In the Settings menu, find "Real-Time Scanning" or "On-Access Scanning" — the exact name depends on your McAfee version. You will see a toggle switch next to it. Click the toggle to turn it off. McAfee will ask you to confirm; select "Yes" or "Turn Off." Your antivirus is now disabled and will remain off until you turn it back on manually or restart your computer.

Adding a program to McAfee exclusions instead

If McAfee is blocking a specific program you want to run, you do not have to disable the entire antivirus. Instead, add that program to the exclusions list so McAfee ignores it. Open McAfee Settings and look for "Exclusions," "Quarantine," or "Threats."

Select the option to add an exclusion or restore a quarantined file. You will need to browse to the program's location on your computer — usually in Program Files or Program Files (x86) on Windows. Select the .exe file or the entire folder and confirm. McAfee will now skip scanning that program, and you can run it without disabling your entire antivirus.

Re-enabling McAfee protection

Once you have finished the task that required McAfee to be off, turn protection back on when ready. Open McAfee, go to Settings, find Real-Time Scanning, and click the toggle to turn it back on. Confirm the change when prompted.

If you paused McAfee and the pause time has already expired, protection will have resumed automatically — you do not need to do anything. If you are unsure whether McAfee is currently protecting your computer, look at the main McAfee window: a green shield or a message saying "Protected" means it is on. A red or gray shield means it is off.

What to do if you cannot change these settings

Some computers are set up so that only an administrator can change antivirus settings. If you try to disable McAfee and nothing happens, or you see a message saying "You do not have permission," you need administrator access. Right-click the McAfee icon and select "Run as Administrator," then try the steps above again.

If you still cannot disable it, your computer may be managed by an employer or school. Contact your IT department or help desk — they control these settings and can disable McAfee for you or add exclusions on your behalf.

Uninstalling McAfee completely versus disabling it

Disabling McAfee is temporary and reversible. Uninstalling it removes the software from your computer entirely. If you only need McAfee off for a few minutes or hours, disable it. If you want to remove it permanently because you prefer a different antivirus or do not want antivirus software at all, uninstall it through Windows Settings or the Control Panel.

To uninstall, open Settings, go to Apps or Programs and Features, find McAfee in the list, and select Uninstall. Follow the prompts to remove it. Your computer will have no antivirus protection after uninstalling, so install a replacement before you uninstall McAfee, or do it only if you are certain you do not need antivirus software.

Frequently Asked Questions

Will my computer get infected if I disable McAfee for 30 minutes?

The risk depends on what you are doing. If you are installing a legitimate program from a trusted source, the risk is very low. If you are browsing the internet or opening email, the risk is higher. Disable McAfee only for the specific task you need, then turn it back on right away.

Why does McAfee keep turning itself back on?

McAfee is designed to re-enable automatically after a pause period ends or when you restart your computer. This is a safety feature. If you disabled it manually and it keeps turning back on, your computer may be set to require administrator permission to change antivirus settings, or McAfee may have a scheduled task that re-enables it.

Can I disable just the firewall part of McAfee and leave the virus scanner on?

Yes. In McAfee Settings, you can usually find separate toggles for Real-Time Scanning (virus protection) and Firewall. You can turn off one and leave the other on. This is useful if the firewall is blocking a program but you still want virus protection.

What is the difference between pausing and disabling McAfee?

Pausing stops protection for a set time — 15 minutes, one hour, or until restart — and automatically resumes. Disabling turns off protection until you manually turn it back on. Pausing is safer because you cannot forget to re-enable it.
