Remove security parameters
If your computer is connected to a network or the Internet, it is advisable to use computer security tools, such as a firewall, to protect your computer from unauthorized access or viruses. Windows operating systems come with a built-in firewall, malware protection and Internet security. These settings are automatically configured to the factory's default settings when you purchase the operating system. To alter the settings for these security features, access the Windows Security utility through your system's Control Panel.
Open the "Windows Security" utility by opening your "Start" menu and selecting the "Control Panel" option on the right-hand side. Windows XP users can click on the "Security Center" link in this window. For Vista users, click on the "Security" option, and then click on "Windows Security Center." Click on the "Windows Firewall" option to change the settings for your firewall, if you are using XP. You can turn the firewall on or off, and also configure which programs are allowed through the firewall. Vista users should click on the "Windows Firewall" link in the left window pane and click on the "Change settings" link. In this window, you can block programs from passing through your firewall and grant access to new programs. Click the "Internet Options" selection to configure your Internet security settings. You can raise or lower the security level for different zones using preset configurations, or you can create a custom security level. You can also reset the Internet security level to its default settings. Click on "Automatic Updating" in the Windows Security Center to configure your system's update settings. In Vista operating systems, click on "Windows Update" and "Change Settings." You can configure your update settings to automatically check for updates daily or weekly. You can also set a convenient time for your system to update to prevent interruption. Automatic updating can be turned off by selecting the corresponding option toward the bottom of the window. Select the "Malware Protection" option to edit malware settings if you are using Vista. This option is not available in XP's version of Windows Security Center. You can turn the malware protection programs on or off using the arrow to the right of the "Malware Protection" bar. Click the "X" button to exit Windows Security Settings.
