For PC users, the Windows security centre is a system configuration center that allows you to verify the presence of an antivirus program and check its operating status. The Windows Security Center is located in the Control Panel and always displays an "ON" message if it determines that an antivirus program is installed on your computer. Whenever an antivirus program is outdated, the Security Center displays an "Out of date" message, signifying that you should update your security program.

Hence you can cross-check the status of your antivirus.
