Frequently Asked Questions about Internet Security Software

What is a personal firewall and how does it protect my computer?

Most security software programs include a personal firewall, which is a version of the same technology businesses use to protect their networks. A personal firewall manages who and what have access to your computer system based on certain pre-determined rules built into the software. For example, when you attempt to download a program from the Internet, a personal firewall may warn you or block the download of that program altogether if it is known to be detrimental to your computer's health. In addition, a personal firewall will prevent any outbound attempts by programs already on your computer to connect to the Internet without your knowledge. This is important because it is possible for hackers or identity thieves to access your personal information if you inadvertently download a program that allows them to transmit information from your computer through the Internet. There are other less nefarious programs that may just want to send the creator information about what websites you visit online or other behavior that you may want to keep private.
