Method 3: Remove all traces of other security programs from the computer
Make sure that all traces of the security programs that are installed on the computer are removed. This includes any free or trial products that were pre-installed when you bought the computer, even if they were never activated. Also, make sure to completely uninstall the security program that you were using before you installed Microsoft Security Essentials. Some security programs have their own firewall. By removing these products, the Windows Firewall will be enabled. By default, MSE uses the Windows Firewall.
Note: Security software includes programs such as anti-virus, anti-spyware or anti-malware programs.
If you aren't sure what security programs are installed on the computer, you can use the AppRemover utility from OPSWAT, Inc. to identity the software. To obtain AppRemover, visit http://www.appremover.com/.
After you identify the security programs that are installed on the computer or have been partially removed from the computer, you can use a cleanup tool or instructions from the security program manufacturer to completely remove the program.
For more information about the cleanup tools that are available for a specific product, see 2688686: List of security program cleanup and uninstall tools.
After all other security programs are removed and cleanup is completed, restart the computer, and then verify that Windows Firewall is turned on. You can check the status of the Windows Firewall in the Action Center (or Security Center if you are using Windows XP), or by using Control Panel.
- For information about Action Center, see What is Action Center?
- For information about Security Center, see Using Windows Security Center.
- For information about using Control Panel to check Windows Firewall status, see Turn Windows Firewall on or off.
