Best firewall software to protect your computer

What is difference between firewall and antivirus software?

Antivirus and firewall software both performs the function of protecting your data from intruders who try to use your data and personal information unintentionally. But they work in different conditions with different context.

Antivirus program tries to find the harmful software on your computer by scanning already installed programs and data on your hard disk and attempts to neutralize the effect of this harmful software, which is commonly known as virus. Antivirus program does not intend to watch and protect your internet connection and thus if you have only antivirus program installed on your system, some virus may affect your system, which could be cleaned using the antivirus.

On the other hand, the basic function of a firewall is to watch your internet connection. If firewall finds something suspicious in your incoming or outgoing data, it terminates that connection and gives warning to the user. Firewall also scans a file when it is being downloaded but antivirus can scan a file when download is completed and thus antivirus may allow some viruses to be installed on your computer. So to protect your PC completely from attacks and to prevent intruders to steal your information you must have a good combination of antivirus and firewall software.
