Warning
You should not turn off Windows Firewall unless you have another firewall enabled. Turning off Windows Firewall might make your computer (and your network, if you have one) more vulnerable to damage from worms or hackers.
In addition to a firewall, you also need an antivirus and anti-malware program to help protect your computer. Install Microsoft Security Essentials or another antivirus and anti-malware program, and keep it up to date. Many of these programs update automatically.
