[15072] Program not able to access the Internet after product installation


Summary

This article provides information about the following issue in F-Secure Internet Security 2010: a program cannot access the Internet after product installation.




Problem description

Once you have completed installing the product, some of the programs on your computer that require access to a network or the Internet may not work.

The most probable reason for this issue is that either Windows Firewall or a third-party firewall is active. Using multiple firewalls on one PC might lead to interoperability and networking issues.




Solution

To solve the issue, disable Windows firewall or a third-party firewall if it is active.

Disabling Windows Firewall

To disable Windows Firewall in Windows XP:

  1. Click Start and select Control Panel.
  2. If the "Pick a category" view is displayed, click Switch to Classic View in the left pane to display all Control Panel icons.
  3. Double-click the Windows Firewall icon to open the Windows Firewall dialog.
  4. On the General tab, select Off (not recommended) to turn off the Windows Firewall feature:

  5. Click OK to verify the change.
  6. We recommend that you restart your computer to ensure that the setting is on.

To disable Windows Firewall in Windows Vista or Windows 7:

  1. Click Start and select Control Panel.
  2. Browse to the Security category and double-click Windows Firewall. The Windows Firewall window is displayed.
  3. Click Turn Windows Firewall on or off. The Windows Firewall Settings dialog is displayed. Note: If you are prompted for an administrator password or confirmation, type the password and/or confirm.
  4. On the General tab, select Off (not recommended) to turn off the Windows Firewall feature:

  5. Click OK to verify the change.
  6. We recommend that you restart your computer to ensure that the setting is on.

Disabling third-party firewall products

The second most common reason for the described issue is that a third-party firewall product is still installed on the computer. Check through Control Panel that there are no other products with firewall installed on the computer.

To disable a third-party firewall in Windows XP:

  1. Click Start and select Control Panel.
  2. Double-click the Add or Remove Programs icon.
  3. Go through the "Currently installed programs" list and uninstall any third-party firewall or third-party product with a built-in firewall by clicking Remove.
  4. Restart your computer.

To disable a third-party firewall in Windows Vista and Windows 7:

  1. Click Start and select Control Panel.
  2. Double-click the Add or Remove Programs icon.
  3. Open Programs.
  4. Open Programs and features.
  5. Go through the "Currently installed programs" list and uninstall third-party firewall or third-party product with a built-in firewall by clicking Remove.
  6. Restart your computer.
