For a quick overview of your security settings, the Windows Security
Center is where you'll find the status of your system firewall, auto
update, malware protection and other security settings. Click Start,
Control Panel, Security Center, or you can simply click the shield icon
in the task tray. If you see any red or yellow, you are not fully
protected.
For example, if you have not yet installed
an antivirus product on your machine, or if your current antivirus
product is out of date, the malware section of the Security Center
should be yellow. Windows does not offer a built-in antivirus utility,
so you'll want to install your own. For free antivirus, I recommend AVG
Anti-Virus 8.
