McAfee says “not protected” or will not update: what to check

Work through the steps in order and stop once McAfee shows that you are protected. Allow about 12 minutes, more if you reach step 6. McAfee changes its app layout from time to time, so the exact wording may differ by version.

1. Check that the subscription is active

   An expired subscription is the most common reason for “not protected”. When it ends, McAfee stops updating and may switch real-time scanning off.

   1. Open McAfee from the Start menu and look on its home screen or account page for the subscription status.
   2. To confirm, type mcafee.com into your browser, sign in, and open My Account. Note the status and expiry date.

   Many new PCs come with a McAfee trial preinstalled, often for about a month. When it ends, McAfee stays on the PC but stops protecting it. If you never activated or paid for a subscription, this is almost certainly the cause.

   If	Then
   The subscription is active	Continue with step 2. If the app still says expired, an update usually refreshes it.
   The trial or subscription has ended	Decide whether to renew it in your account, or remove McAfee completely so that Microsoft Defender, which is part of Windows, takes over.

2. Run Check for updates

   McAfee needs current threat definitions to protect you, and a stalled update also shows as “not protected”.

   1. Make sure the PC is connected to the internet.
   2. Right-click the McAfee icon in the notification area near the clock. If you cannot see it, select the small up arrow first.
   3. Choose Check for updates. If that option is not there, open McAfee and look for it in the settings or account menu.
   4. Wait until McAfee says it is up to date, then restart the PC.

3. Turn Real-Time Scanning back on

   Real-time scanning checks each file as it is opened, so it is the heart of the protection. It can stay off after an earlier troubleshooting attempt or a pause that never resumed.

   1. Open McAfee. If the home screen shows a Fix or Turn on button next to a warning, select it.
   2. Otherwise look for Real-Time Scanning, often under My Protection or in the settings menu.
   3. Select Turn on. Turn on any other item on that page that shows as off, such as Firewall.

4. Remove a second antivirus

   Two antivirus programs scanning at once can block each other’s updates. Microsoft Defender does not count: it steps aside by itself while McAfee is active.

   1. Select Start, type Windows Security, and open it.
   2. Select Settings (the gear at the bottom left), then Manage providers.
   3. Under Antivirus, look for any product other than McAfee and Microsoft Defender Antivirus.

   If you find one, uninstall the product you do not want from Settings › Apps › Installed apps. Restart, then repeat step 2.

5. Correct the clock and install Windows updates

   McAfee checks your subscription and downloads updates over secure connections, which fail when the PC’s clock is wrong.

   1. Press Windows + I and go to Time & language › Date & time. Turn on Set time automatically, then select Sync now.
   2. Select Windows Update (in Windows 10, Update & Security › Windows Update), then Check for updates, and install what it offers.
   3. Restart, then run McAfee’s Check for updates again.

6. Reinstall McAfee cleanly

   If McAfee still will not update, the installation is probably damaged. A normal uninstall can leave pieces behind, so McAfee provides a removal tool that clears them before you install a fresh copy.

   1. In Settings › Apps › Installed apps (Windows 10: Apps & features), select the three dots next to each McAfee entry, then Uninstall. Restart.
   2. Get the McAfee Consumer Product Removal tool (MCPR) only from McAfee’s own website: type mcafee.com/support into the address bar and search for MCPR. Download a fresh copy each time.
   3. Run MCPR, accept the agreement, type the security code it shows, and wait for Removal Complete. Restart again. If it reports that cleanup was unsuccessful, run it once more.
   4. Sign in at mcafee.com, open My Account, and choose the option to download or install McAfee on this PC. Install it, sign in, and run Check for updates.

7. Use McAfee’s official support if it still fails

   If a fresh install still reports that you are not protected, the cause is likely on the account side, or a fault only McAfee can diagnose.

   Type mcafee.com/support into your browser’s address bar yourself. McAfee’s help articles and the contact options for your account are there. Never use a phone number from a search ad, a pop-up or an email, even one showing the McAfee logo; scammers copy the branding closely.

   If you decide not to keep McAfee, remove it completely and let Defender take over.
