How to active Windows Firewall
Windows Firewall (first released as part of Microsoft Windows XP Service Pack 2)
Windows Firewall protects your computer by blocking communications that might actually be dangerous software trying to find a way to connect to your computer, rather than communications from a person or program you want to interact with.
Windows Firewall is smart enough to allow connections from computers in your home and to block those connections from computers on the Internet. For example, Windows Firewall will allow you to share files or a printer between two computers in your home, but it will block any attempts from people on the Internet to connect to your computer.
What Windows Firewall does and does not do.
Windows Firewall does offer some protection from network attacks from malicious software known as worms. However, Windows Firewall does not protect you from viruses or spyware
To verify that Windows Firewall is protecting your computer
- Click Start and then click Control Panel
- From the Control Panel, click Security Center
If Windows Firewall shows OFF, it has been disabled. If you have another firewall installed, this is probably OK. If you don?t have another firewall installed, you will need to re-enable Windows Firewall from within Security Center.
To re-enable Windows Firewall
- Click “Recommendations”
- Click “Enable Now”
