A firewall is a tool or a number of tools made usually to protect networks from unapproved access. Many PC’s operating system has firewall built in to protect against threats from the internet. There are several types of firewall features such as packet filter, application gateway, circuit level gateway and proxy server. Some of the things that firewall can not prevent are e-mail viruses. A firewall can’t see what is inside an email so it can’t protect you from these types of viruses. By using an up-to-date antivirus program and being careful about opening file attachments and clicking links in messages, you should be able to avoid polluting your computer with a virus from nasty e‑mail.
