from the

Red alerts
Red alerts contain important information that requires your immediate attention:
Internet Application Blocked
— This alert appears if Personal Firewall blocks an
application from accessing the Internet. For example, if a Trojan program alert
appears, McAfee automatically denies this program access to the Internet and
recommends that you scan your computer for viruses.
Application Wants to Access the Internet
— This alert appears when Personal
Firewall detects Internet or network traffic for new applications.
Application Has Been Modified
— This alert appears when Personal Firewall
detects that an application, previously allowed to access the Internet, has
changed. If you have not recently upgraded the application, be careful about
granting the modified application access to the Internet.
Application Requests Server Access
—
This alert appears when Personal
Firewall detects that an application you have previously allowed to access the
Internet has requested Internet access as a server.
NOTE
The Windows XP SP2 default Automatic Updates setting
downloads and installs updates for the Windows OS and
other Microsoft programs running on your computer without
messaging you. When an application has been modified from
one of Windows silent updates, McAfee Personal Firewall
alerts appear the next time the Microsoft application is run.
IMPORTANT
You must grant access to applications that require Internet
access for online product updates (such as McAfee services) to
keep them up-to-date.
Internet Application Blocked alert
If a Trojan program alert appears ( Figure 3-4 ), Personal Firewall automatically
denies this program access to the Internet and recommends that you scan your
computer for viruses. If McAfee VirusScan is not installed, you can launch McAfee
SecurityCenter.
