17	Recommendations for improved network security Always maintain an updated antivirus on all computers within a network Perform Windows Update regularly (better to set it to automatic updates) Open internet explorer and click on “tools” then “windows update” Keep going back to windows update until all critical updates have finished. Upgrade to Microsoft Update to include your Microsoft Office products in the update process. Turn on Windows XP firewall. Start, Control Panel, Windows firewall. If you are running Windows 98, ME, or 2000 professional consider getting firewall protection for these operating systems from 3rd party vendors. There are many free firewall programs available. Note: Installing a firewall program on a computer may prevent it from being able to share printers or files. Don’t make changes to your computers or network without first consulting with your network administrator. For safer internet access insure that your office uses a router that blocks unsolicited incoming traffic.
