Well, you've made it to the firewall page.   I'm also going to include a few links to other security utilities here as well.   It is essential that you have a firewall as well as anti-virus.   This will protect your computer from any threats from hackers.

The Internet is still a great place, you just need a few layers of protection to make your experience a safe and pleasant one.   I have links to reviews on which is the best firewall, to security checks for your computer so you can see if there are any security leaks you need to take care of.  

Here I have a few miscellaneous apps that might make your Internet experience a little more pleasant.   There are links to free Pop-up Stoppers to a Mailwasher utility that will keep Spam and viruses from ever being downloaded to your computer.
