66 McAfee Internet Security About alerts Firewall has three basic alert types. As well, some alerts include information to help you learn or get information about programs running on your computer. Red alert A red alert appears when Firewall detects, then blocks, a Trojan on your computer, and recommends that you scan for additional threats. A Trojan appears to be a legitimate program, but can disrupt, damage, and provide unauthorized access to your computer. This alert occurs in every security level. Yellow alert The most common type of alert is a yellow alert, which informs you about a program activity or network event detected by Firewall. When this occurs, the alert describes the program activity or network event, and then provides you with one or more options that require your response. For example, the New Network Connection alert appears when a computer with Firewall installed is connected to a new network. You can specify the level of trust that you want to assign to this new network, and it then appears in your Networks list. If Smart Recommendations is enabled, known programs are automatically added to the Program Permissions pane. Green alert In most cases, a green alert provides basic information about an event and does not require a response. Green alerts are disabled by default. User Assistance Many Firewall alerts contain additional information to help you manage your computer's security, which includes the following: ƒ Learn more about this program: Launch McAfee's global security Web site to get information about a program that Firewall has detected on your computer. ƒ Tell McAfee about this program: Send information to McAfee about an unknown file that Firewall has detected on your computer. ƒ McAfee recommends: Advice about handling alerts.
