How Can I Tell if I Have a Firewall?

Dell Computers ship with McAfee, Symantec or Trend Micro security products.

If you have McAfee Security Center, perform the following steps:
Right-click the McAfee icon in the system tray, point to Personal Firewall, and then click View Summary to check the status of the Personal Firewall.
If you have Symantec's Norton Internet Security, perform the following steps:
Right-click the Norton Internet Security icon in the system tray, and then click Open Norton Internet Security to check if Personal Firewall is "On" or "Off" under System Status.
If you have Trend Micro's PC-cillin Internet Security, perform the following steps:
Click Start, point to All Programs, Trend Micro PC-cillin, and then click Trend Micro PC-cillin Internet Security.
Click Network Security, and then click Personal Firewall to check if the firewall is enabled or disabled.
If you did not find one of the previous firewall products installed on your PC, you may be running an operating system that came with a simplified firewall feature set. If you are using the Microsoft Window XP Service Pack 2 (SP2) operating system, you can check to see if your firewall is turned on through the Windows Security Center.
Click Start, and then click Control Panel.
Click Security Center, and then click Windows Firewall.
If you have Windows XP, but you do not have Service Pack 2 running on your computer, you can download SP2 by visiting the Microsoft Update Web site. You can also check to insure that the firewall is enabled with the following steps:
Click Start, and then click Control Panel.
Click Network and Internet Connections, and then click Network Connections.
TIP: If the Network and Internet Connections category is not visible, click Switch to Category View on the upper left of the window.

Under the Dial-Up or LAN or High Speed Internet category, click to select the icon of the connection you want to help protect.
In the task pane on the left, under Network Tasks, click Change settings of this connection (or right-click the connection you want to help protect, and then click Properties ).
On the Advanced tab, under Internet Connection Firewall, make sure the box is checked next to Protect my computer and network by limiting or preventing access to this computer from the Internet. If a check mark is in the box, the firewall is already enabled. If the box is clear, the firewall is off and your computer is potentially vulnerable on the Internet.
