68 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, except Open. 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 Detected alert appears when a computer with Firewall installed is connected to a new network. You can choose to trust or not trust the network. If the network is trusted, Firewall allows traffic from any other computer on the network and is added to Trusted IP Addresses. If Smart Recommendations is enabled, programs are 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, and usually occur when Standard, Trusting, Tight, and Stealth security levels are set.
