The CDs we give out with our power point presentation include free software for PC security (Spyware, Adware, Virus etc) but I had not found a free Firewall until yesterday. I found a free suite called Comodo Internet Security. Wakcopa describes the software: Comodo Internet Security is the free, multi-layered security application that keeps hackers out and personal information in. Built from the ground upwards with your security in mind, CIS offers 360° protection by combining powerful Antivirus protection, an enterprise class packet filtering firewall, and an advanced host intrusion prevention system called Defense+. I have installed Comodo Internet Security on three of our computers. The Antivirus Software found a couple of items my other software missed. The firewall appears to be sophisticated and for the advanced user yet simple for the novice. I will be adding this software to our CD and replace the AVG AntiVirus we currenlty have on there. Nobody should be without good AntiVirus Software and a good firewall. Comdodo takes away your excuses.
