Computers that are connected to a network or the Internet are open to a variety of attacks. You can install some forms of protection, such as an antivirus program or malware protection, to help thwart these attacks. Additionally, you can install or activate a firewall on your computer to allow or block network transmissions on your computer. Windows 7 installations include the Windows Firewall by default, but some other security programs can change your settings to use their own firewall. You can check your firewall status at any time within Windows. Tips Writer Bio
