Windows 7: Do I need a firewall, and if so, what kind?

Do I need a firewall, and if so, what kind?

I keep hearing about "firewalls" for my computer and that there are different types. Do I need one? If I do, what kind of firewall do I need?

The very short, very easy answer is: hell yes! Absolutely, positively you need a firewall.
With all that happens on the internet these days it's simply too risky to let your computer sit "naked" on the internet unless you really know what you're doing.
The real question is then: what do you need?
Heck, it's even possible you already are behind a firewall and don't need anything more.

I think for many, the use of a hardware based router with NAT translation coupled with the built-in Windows firewall is often enough. Then, obviously the use of an AV app and a malware/spyware scanner app and you should be set.

To prevent a virus and other bad things, depend on yourself not your A/V.

So, what happens in the event that a trusted site that you frequently use, gets hacked and a normally trusted .exe file is replaced with something that isn't trustworthy. What is a DNS hack happens and you are directed to a fake site that looks just like the real site. This is where your Anti-Virus app comes into play. Unfortunately, being knowledgeable doesn't always save you.

Bad things can happen to anyone. I am suggesting to be careful. I try my best, and I was saved once by my A/V. It happens to everyone.

Inbound Protection....

An absolute need. Prevents things from getting access to your computer. If you are behind a router then you are most likely protected from the internet. However if not, or if you want to protect yourself from other computers on the network (like the Starbucks wireless, etc) then you need a locally installed Software Firewall to block Inbound queries.

Outbound Protection....

There is alot of controversy about this but don't listen to it... you NEED this. This prevents programs that are on your computer from getting out to the internet. All those spyware programs you hear about that collect data, or passwords, key loggers, etc and then send that data to the bad guys.... well outbound is the only thing that will stop them. (Of course hopefully your AV and AntiSpyware programs prevented these from getting installed but that is not always the case)

well someone said above...bad things can happen to anyone...he is right.
but i tell u something.it all depends on u... i dun use AV,its almost 3-4yrs,just a simple firewall to prevent pinging and hacking(although hackers can do anything,firewall doesnot matter) but just for mental satisfaction,i use zonealarm,i trust it too much,it is dam good.but it is complex,it annoys too much to a new user, one has to be expert to use it,it asks every single single process to proceed with it.but if u once got to know how it works,its best.
now AV,i didnt try much,but in my opinion if u have a good system which can hold mcafee,it is best AV,i recommend it,but it is little heavy on system resources so all systems cannot hold it well...
rest depends on u.
