How secure is your computer? Have you downloaded the latest patches and updates for Windows? As Internet usage has grown, so have security threats. One way to protect yourself is to install a firewall, which keeps intruders from sneaking into your computer and accessing your private data. Firewalls also can alert you when spyware programs attempt to transmit your sensitive information over the Internet. In particular, firewalls are crucial if you have the always-on Internet connection of DSL or a cable modem. Protect yourself and your family.
