Update your antivirus software

Antivirus software must be updated regularly to stay effective against new viruses. Most antivirus software is designed to update automatically, but you can also update your software manually.

Windows doesn't come with antivirus software, but it can often detect and monitor antivirus software that was installed by you or your computer manufacturer. The status of your antivirus software is typically displayed in Action Center.

  1. Open Action Center by clicking the Start button Picture of the Start button, clicking Control Panel, and then, under System and Security, clicking Review your computer's status.

  2. Click the arrow button Picture of the arrow button next to Security to expand the section.

    If Windows can detect your antivirus software, it will be listed under Virus protection.

  3. Click Update now.


  • The Update now option only appears if Windows detects that your antivirus software is out of date. Not all antivirus software reports its status to Windows.

If your antivirus software isn't displayed in Action Center, go to the downloads section of your antivirus software provider’s website. Find the update for your version of the software and your operating system, and then install it. For more information, check the Help for your antivirus software.

Most antivirus software updates are free, but some providers charge a small fee for the updates. If you're using an older version of the software, you might also have to pay to upgrade to a more recent version to continue to receive the updates.
