McAfee Help

Personal Firewall serves as a defensive barrier between the Internet and your PC, allowing you to control what comes in and what goes out. The functionality of Personal Firewall is tailored to monitor Internet traffic for suspicious activity, and to provide effective protection without disrupting your activities.

This protection feature might not be turned on, installed, or included in your McAfee software. To learn about the protection features included in your McAfee suite, read Understanding your protection features.

•	Personal Firewall features
•	Starting Personal Firewall From the moment you install Personal Firewall, it begins protecting your PC from intrusion and unwanted network traffic. Smart Advice is automatically enabled, helping you handle alerts, and you can manage access for known and unknown programs. By default, Personal Firewall is set to allow outgoing access for programs. If Personal Firewall is not installed, the Home Page shows the status of any other firewall protection you might have. If no other firewall is installed, Home Page shows the status of your Windows firewall.
•	Working with alerts Alerts appear in the bottom right corner of your screen to let you know when security events occur on your PC. An alert provides information about an event, as well as recommendations and options for resolving security problems.
•	Setting up Personal Firewall protection Personal Firewall lets you choose how to manage your security, including how to respond to threats and alerts.
•	Managing Personal Firewall security types Part of choosing the security that works best for you is deciding how you want to manage alerts and respond to them. Alerts appear when Personal Firewall detects an intrusion attempt, unwanted network traffic, or suspicious activity from incoming or outgoing Internet connections. By default, the security type is set to Smart Access, which allows known programs to send information to and from your PC.
•	Changing advanced settings Personal Firewall lets you choose how you want to be notified about allowing or blocking programs that require Internet access. Personal Firewall also lets you manage how your PC handles programs trying to access the Internet at startup, how it communicates with other PCs, how it handles intrusion attempts from hackers, and even how it reports on your security vulnerabilities.
•	Customizing Personal Firewall security Personal Firewall allows you to control program activities that can compromise the security of your PC. You can control how your PC handles intrusion attempts from hackers, how it blocks risky connections, and even how it reports on your security vulnerabilities.
•	Blocking and restoring Internet access You can block Internet access instantly by selecting the Lockdown security type.
•	Managing Internet connections for programs Some programs on your PC need to make incoming and outgoing connections to the Internet. You can choose the type of connection for your programs, and block them from connecting to risky sites.
•	Managing PC connections You can configure Personal Firewall to manage specific remote connections to your PC.
•	About system services To work properly, certain programs (including web servers and file-sharing server programs) must accept unsolicited connections from other PCs through designated system service ports. Typically, Personal Firewall closes these system service ports because they make your PC more vulnerable to attacks. To accept connections from remote PCs, however, the system service ports must be open.
•	Setting up system service ports You can set up system service ports to allow or block remote network access to a service on your PC. These ports can be opened or closed for PCs that are listed as Home, Work, or Public in your Connections list.
•	Event Logging Personal Firewall allows you to enable or disable event logging. When it's enabled, you can also specify which event types to log. With event logging, you can view recent incoming events, outgoing events, and intrusion events. Personal Firewall records an event each time an Internet connection attempt is blocked.
•	Viewing HackerWatch statistics Personal Firewall uses the security website HackerWatch to provide up-to-date information about programs and global Internet activity. HackerWatch is associated with McAfee and is integrated with Personal Firewall, allowing individual users to pool information through automatic event submission, which helps prevent hacking attempts, intrusion, and unwanted traffic. By combining this data, automated tools scan for offending PCs, which can be identified by the Internet traffic they produce. When an offending PC is identified, its Internet service provider is notified so that they can respond by removing access.
•	Monitoring Internet traffic Because many Internet service providers have limitations on the bandwidth you can use per month, you might want to find out which of your programs use the most bandwidth on your network.
•	Learning about Internet security Personal Firewall uses HackerWatch, a McAfee security website, to provide up-to-date information about programs and global Internet activity. HackerWatch also provides an HTML tutorial about Personal Firewall.
