Well here is another FREE service if you are looking to obtain an Internet Firewall to protect you from hackers from invading the confines of your PC. Now, you can settle for Windows Service Pack 2 Firewall however, I have found this not to be so advanced nor that effective.

However, I have found a Free solution, that not only protects you from hackers, but also scans for viruses and spyware. Its Called Comodo Firewall service and you can obtain this at http://www.personalfirewall.comodo.com/

Here are some of the features you get, and yes all for FREE:

• Complete protection from Hackers, Spyware, Trojans and Identity theft
• Host Intrusion Prevention System stops malware from being installed [NEW]
• Clean PC Mode registers your current applications then will allow only applications that you approve to be installed on your computer [NEW]
• Malware Scan Feature checks your computer for viruses, spyware and trojans before you install Comodo Firewall Pro [NEW]
• Free Download. No charges or license fees ever.
