Antivirus software and firewalls are critical for your computer's security.
Antivirus programs protect your computer from viruses that can get installed on your computer. However, nowadays, most antivirus programs protect your computer from more than just viruses, they also detect and remove worms, Trojans, rootkits, etc.
Firewalls protect your computer from hackers and malware that may want to connect to your computer and cause havoc. They do this by using a packet-sniffing technology that detects malicious patterns in your network traffic.
If you don't have a good antivirus and firewall installed on your computer, you may be infected and not even know it.
