Hey
I have problem regarding antivirus and firewall. I installed avg antivirus on my pc, but virus attacked on my system again, somebody told me to install any firewall. I am using cable internet. Can anyone help me with the difference between anti virus and firewall? Thanks in advance.

The packet firewall blocks attacks or attacks port or Intrust people in the Internet.Where asAnt Virus program control or protect against malware already on your computer to do bad things, or attempt to reverse the damage caused by them, and the removal of bad programs.

A firewall is a software component, adjust the program installed on your system using the Internet. Most firewalls do not stop there. Anti-virus tools to scan your computer detect and clean viruses and other malicious software, files and registry. Its real-time components to prevent the installation or start the malicious program for the first time.

The Difference between Antivirus and Firewall is

- Antivirus software is used to prevent, detect, and remove malware, including computer viruses, worms, and trojan horses.

- Firewall is a part of a computer system or network that is designed to block unauthorized access while permitting authorized communications. It is a device or set of devices configured to permit, deny, encrypt, decrypt, or proxy all computer traffic between different security domains based upon a set of rules and other criteria.

This is nice difference between anti virus and firewall that you provide in this thread. I really like it very much. It is too useful for me to know about the anti virus and firewall. As per my knowledge firewall protect from spy and anti virus will help you from virus.

A firewall is a program that is located between you and the Internet, analyze the incoming and outgoing traffic, trying to block threats to your security. It is mainly looking for hacker attacks. As long as your Internet connection is open it like a door hackers. A good firewall makes your PC will not be visible most of the hackers. If they can not see you, they can not break it, it is not foolproof, so the anti-virus, anti trojan, anti-adware and anti-spyware software is your next line of defense. They scan your system for malicious software, is all forward-looking in order to install or run.

A firewall is a software component, you use the Internet to adjust the program installed on the system. Most firewalls do not stop there. Anti-virus tool to explore your computer viruses and other malicious software to scan files and registry clean. The real-time components to prevent installation or first start for the malicious program.

I would simply say that firewall is that software which protects while online, its like a "wall" which stops attacks to your computer. anti virus is that software, which remove virus which are already on the pc

A firewall helps you block unauthorized access for outside to your computer.
An antivirus helps you scan, clean and detect viruses-a kind of malicious computer code.

The prime job of an anivirus is protect your system from computer viruses. Your computer may be standalone or part of network or connected to Internet you need an antivirus program. It actively monitors when you are using your system for any virus threat from different sources. if it found one it tries to clean or quarantine the virus ultimately keeping your system and data safe.

Firewall is in other hand a program which protects your system from outsider/intruder/hacker attacks. These attacks may not be virus type. In some cases hackers can take control of your system remotely and steal your data or important information from system. If your system is directly connected to internet or a large network than you can install a software firewall in your PC to protect your self from unauthorized access. Firewall is available either in software or in hardware form. For a single PC you may need a software firewall while a large corporate implements hardware firewall to protect all of their systems from such attacks.
