Why do i need antivirus if i have Firewall??

Hi Branden,

Antivirus a software used to prevent and remove malware or any other computer viruses.

Firewall is a barrier designed to prevent unwanted programs in a network. 

There are three types of firewall:

• Software firewall.
• Hardware firewall.
• Wireless router.

You can determine which type of firewall you are going to use: How many computers and what Operating System did you use?

I think you mentioned about your personal computer. Since you are using Windows XP SP2, so you have to turn it ON by default.

Then now you are using a software firewall package from your operating which is Windows.

Yes, it is necessary to have Anti-virus even if you have the firewall. The scenario would be like this; the firewall you are using is to prevent unwanted programs in a network so if you are connected with (LAN) local area network and a (WAN), your PC is free from viruses and a malwares because it can't enter through the firewall BUT everyday (daily or anytime) reported that there is an update of the virus, malware, spyware, etc. and you do not update your software into Windows higher version and also the firewall your are using, so possible this time unwanted programs can enter through you firewall.

That is why you need also to install your Anti-virus software and be sure it is updated also for its purpose is to scan whatever unwanted programs infected in your personal computer.

Because of the fast update of any software, I can't determine what is the best between the firewall and the anti-virus. However, I can recommend to use that two tools as security and maintenance of your PC.

The job of Firewall is to prevent meaning it wont allow any programs that can harm your computer.

Ex.  

• A man with a bulletproof.
• Bulletproof is the firewall while the bullet is the virus.
• So the bullet  cant destroy the man because he has a bullet proof.

The job of the Antivirus is to remove or kill the virus in your computer.

Firewall has importance even if it can't delete virus in the since that it will inform you that there is a virus entering your computer. So your anti-virus will be able to scan your computer for prevention.

I hope I can share you basic things.
