For maximum protection, we recommend that you let SecurityCenter automatically check for and install updates. However, if you want to only manually update your security services, you can disable automatic updating.
Important: You must remember to manually check for updates at least once a week. If you don't check for updates, your computer is not protected with the latest security updates.
To disable automatic updating:
A confirmation dialog box appears.
If you do not manually check for updates in seven days, an alert reminds you to check for updates.
