Do I Really need a FIREWALL?

Hi friends,

Merry Christmas to all! I'm thinking all of a sudden if 1 really need a firewall? If my browsing is very limited, If I have AV in place with latest update, doesn't linger in the unknown & dark corners of WWW, Do I still need A FIREWALL?

P.S. I have been using Comodo Firewall since its launch in 2005.

Windows 7 has its own firewall, and to the contrary of XP's firewall it is actually useful.

The point of a firewall is keeping doors closed so stuff does not get in. An AV kills what is already inside.

The best defences are always layered, each layer independent of the other.

Do you need a firewall? Maybe not. But you should be asking yourself: can I afford the increase of risk for little or no benefit? (as win7's firewall is not particularly heavy on resources like XP's firewall was)
It would be foolish imho.

Thank you for the above info. @bobafetthotmail. I never had an virus/Trojan attack or PC hacked in the last 10 years. Even though I have been using Comodo since its Day 1. It has been a really satisfactory journey. But I 'm thinking of dumping the idea of using a firewall at all.

Are not firewalls known to give away your own information?? Some giving certificates to Malwares etc.

Here is an example:

I wouldn't go anywhere on the net without one. Your choice I guess, but why take the chance? As bobafetthotmail said 7's firewall is very good. I haven't used a 3rd party one since installing it.

Hmmm may be! I'm not too sure about Windows 7 Firewall. XP firewall was really good though it was heavy on resources.

But here is myth buster on Firewalls:

Didn't see anything to change my mind. Knew all that and nothing in life is "perfect". (except maybe Jennifer Anison )

But look at it this way...... if you were going into a war zone wouldn't you like to have all the protection you could get?

Sunimar if you want to believe in the stories not to use a firewall, thats fine. Its your computer. If you are one of those lucky ones that will never need one that is also okay.
If you are looking for a quality free firewall the one built into Windows 7 works well for millions of people all over the world and might be what you are looking for.
If you are looking just to argue the point, well,
Have a nice day

Win7 Firewall is perfected, should be kept up to date with Windows Updates set to Automatic. It works best in tandem with http://www.microsoft.com/security_essentials/

Any 3rd party Firewall (or AV) will almost always slow down Win7 by comparison. Why do this to the first perfect OS?

All that said, I do not run an AV on my home PC with superior router firewall and Win7 firewall engaged, and I have never been infected. But when friends try this they do sometimes get infected. And with no speed difference to run all three, there's no reason to shy away from the extra protection.

Are you behind a router? A router has its own built in firewall already setup to block all non-internet routable protocols like Windows File Sharing. As well as uninvited inbound connections.

gotta be kidding me.

1. no duh! Btw, hardware firewalls inside a router are generally better and consume 0% system resources (as they are in another device).

2. Kinda obvious. Firewalls filter traffic passing through them, whatever traffic does not pass through them... they do nothing about.

3. this repeats the same point as 2.

4. Obvious. But this does not mean that older threats aren't as real as new ones, and a firewall can keep them at bay with less effort than a AV. (that anyway can destroy only known threats as well). Not to mention that good firewalls based on whitelists (like win 7's) do a decent job at keeping unknown stuff a bay (as they deny access to all stuff they don't know) while AVs do nothing unless they kinda know the threat.

5. correct, note the last line: "Most businesses use a firewall in tandem with a robust anti-virus package for the best possible use."
