Security and privacy

Use the default security settings in Microsoft Office  Office has safeguards in place to help protect your programs and data from viruses. We recommend that you do not change the Office default settings to less secure security settings.
Turn on the security features in the Microsoft Windows Security Center, and keep your computer updated  The easiest way to do this is to visit the Protect Your PC site, which guides you on how to use the Windows Security Center to enable the following:
For more information about antivirus software vendors that you can sign up with, see the Microsoft Antivirus Partners site.
Try a subscription to Windows Live OneCare  Windows Live OneCare is a round-the-clock protection and maintenance service that you can subscribe to. Windows Live OneCare helps protect and maintain your computer by providing all-in-one functionality including virus scanning, firewall, antispyware, PC performance tuneups, and file backup and restore capability. Visit the Windows Live OneCare site for more information and to sign up for a free 90-day trial.
Find out whether you really have a virus  Viruses often run without your knowledge. However, if your computer is acting strangely or if one of your programs is not working correctly, this does not necessarily mean that your computer has a virus. It is important to be aware of the specific symptoms that a particular virus causes. On the Microsoft Security Antivirus Information site, you can find information and alerts about the latest viruses, their severity, and the symptoms they cause.
Check the Microsoft Security Bulletins regularly  An up-to-date list of security issues that affect Microsoft products is available on the Microsoft Security Updates site. This site provides technical information about security issues that affect specific products. If you don't want to remember to check the site regularly, you can subscribe to get security bulletin e-mail notifications for free that let you know about important security updates from Microsoft. In the past, hackers have attempted to mimic these notifications to send bogus information. However, it is not difficult to determine whether a Microsoft security-related message is genuine, because authentic Microsoft security bulletin notifications are always digitally signed and never include software updates as attachments. Instead, the notifications always link to the update on the Microsoft.com Web site.
