Using Internet security software When you use your computer to access email, a network, or the Internet, you potentially expose your computer to computer viruses, spyware, and other online threats. To help protect your computer, Internet security software that includes antivirus and firewall features may be preinstalled on your computer as a trial offer. To provide ongoing protection against newly discovered viruses and other security risks, security software must be kept up to date. It is strongly recommended that you upgrade the security software trial offer or purchase the software of your choice in order to fully protect your computer. Using antivirus software Computer viruses can disable programs, utilities, or the operating system, or cause them to function abnormally. Antivirus software can detect most viruses, destroy them, and in most cases, repair any damage they have caused. Using firewall software Firewalls are designed to prevent unauthorized access to a system or network. The Ubuntu operating system ships with no open ports; therefore, it does not include a firewall utility in the base operating system. However, you may use the Ubuntu Software Center, located in the Launcher on the left side of the desktop, to download Gufw, a free Ubuntu firewall utility. To install Gufw: 1. Click on the Ubuntu Software Center folder located in the Launcher on the left side of the desktop. 2. Enter Gufw in the search bar and press enter. 3. Double-click the Firewall Configuration icon, and then click the Install button. 4. Follow the on-screen instructions. To view or modify firewall settings after installing Gufw: 1. Select Ubuntu Software Center from the Launcher on the left side of the desktop, and then click Gufw. NOTE: When accessing Gufw, you are prompted for the root password. 2. Follow the on-screen instructions. NOTE: Under some circumstances a firewall can block access to Internet games, interfere with printer or file sharing on a network, or block authorized email attachments. To temporarily resolve the problem, disable the firewall, perform the task that you want to perform, and then reenable the firewall immediately. To permanently resolve the problem, you must reconfigure the firewall. Securing your wireless network When you set up your wireless network, always enable security features.
