The debate goes on as to whether a firewall or antivirus program is more crucial and vital to protect your system. It normally depends upon the work and the system's requirements. For this reason antivirus applications have more weight age than any other program.
The reason behind this is that most of the systems are generally protected from any kind of outside intrusions because of the firewall control and router capabilities. On the other hand, using Windows® Vista and Windows XP as the operating systems is still safe as they both have integrated firewall capabilities.
