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.

Set up Intrusion Protection
Most intrusions are targeted at weaknesses in your PC's operating system or programs, which might develop if your operating system or your programs are not getting regular updates. The default setting for Personal Firewall automatically detects the most common intrusion attempts.
Change settings for Protection Alerts
When you turn off Personal Firewall, your PC is vulnerable to threats and your protection status on the Home Page is "at risk."
Block risky connections
You can protect your PC from connecting to risky sites, and also block incoming connection requests from risky sites. Risky sites can be used by hackers and spammers to harm your PC.
Allow or block Internet connections
You can change your settings to allow or block Internet connections for your programs.
