Okay so what’s the difference between a firewall and antivirus software? A firewall is like a fence. It’s designed to keep people out where antivirus software is already if they get in and it looks for unusual and suspicious activity. When a virus gets in, they’re looking to infect computers, to steal data or create zombie or bot computers. Lots of times viruses like to create a network of infected computers to do specific tasks. When you get a firewall, you’re usually going to spend in a small business between 500 to 1500 dollars. For antivirus software you’re usually going to spend about 30, 40 bucks at endpoint. You can often get small business packages which include multiple endpoints and sometimes a server for a few hundred bucks.
