What does it mean?

firewall
A security solution which segregates one portion of a network from another, allowing only authorized network traffic to pass through.

service pack
A tested, cumulative set of all the hotfixes, security updates, critical updates, and updates created to fix defects in a piece of software.

update (noun)
A broadly released fix for a specific problem addressing a noncritical, non-security-related bug.

Nothing can guarantee the security of your computer 100 percent. However, you can continue to improve your computer's security and decrease the possibility of infection by keeping your system up-to-date, maintaining a current antivirus software subscription, and following a few best practices.

Tip

Tip: Because no security method is guaranteed, it's important to back up critical files on a regular basis before you encounter a virus or other problems.

Steps to help avoid viruses

1. Keep your computer software current with the latest Microsoft updates. If you’re running Windows XP Service Pack 2 (SP2), turn on automatic updates.

2. Use an Internet firewall (Note: Service Pack 2 turns on the built-in firewall in Windows XP automatically.)

3. Subscribe to industry standard antivirus software and keep it current.

4. Never open an e-mail attachment from someone you don't know.

5. Avoid opening an e-mail attachment from someone you know until you know exactly what the attachment is. The sender may be unaware that it contains a virus.

6. If you use Microsoft Office applications, it's a good idea to keep them updated too.
