The Difference Between Firewalls and Antivirus Software – And Why You Need Both

Protecting computers and networks are at the forefront of every business owner’s mind. Without sufficient protection from outside threats, a computer and/or network can be crippled, shut down, or remotely operated by a hacker (as with a Trojan horse). Not many businesses today can afford that risk, since computers are crucial to everyday business operations. To protect against such risks, businesses turn to firewalls and antivirus software. However, these two defenses are not the same, and should be combined to ensure your business is protected.

Firewalls

Firewalls are either software or hardware, and offer blanket protection for your computer or network. A firewall acts as a filter between your network and the Internet by analyzing data and determining if it should be allowed to pass either in or out of the firewall. A firewall can protect your computer from Trojan horses and viruses entering your network. However, it cannot scan for viruses or remove malware (including worms, viruses, and Trojan horses). Even though firewalls are a crucial part of your computer and network protection, it can’t do everything. That’s why you need…

Antivirus Software

Antivirus software does have the capacity to scan for, and remove, malware (including Trojan horses and viruses) on your computer. It can also check incoming data, like email. It isn’t perfect, however. You must renew it, which can cause a lapse in protection if you don’t time it correctly. Also, they can sometimes detect a problem when one does not actually exist.

Using both a firewall and antivirus software provides a double layer of protection that prevents your business from having to deal with a compromised network.
