Do i really need a Firewall?

post #1 of 37
Thread Starter 
I currently have McAfee at the mo but its not like it has stopped anything, its just an annoyance when installing softwares...
to allow things all the time

I been thinking of getting norton now, seeing how much its changed
http://www.symantec.com/norton/produ...on.jsp?pcid=mp

but wat i dont understand is does anti virus 2009 include a firewall?
or only the internet security?


and will i really need a software firewall?


i can see why, if a virus does get past the AV atleast it wont be able to receive or send info if i block it on the firewall... but wat are the chances of that, and if it cant get past AV why cant it get past the Firewall

NO! Don't get Norton! It will infect your system just as bad as any virus. It will suck up resources, nag you left and right for permission to do things, and uninstalling it requires additional "cleaner" downloads from Symantec. Norton was good 10 years ago but now there are much better alternatives.

AVG is a great anti-virus and is free! http://free.avg.com/

And spending the money on a a 3rd party firewall software is completely unnecessary. With Vista, you get Windows Defender which is a surprisingly good firewall and doesn't get overly protective and annoying.

From the Norton page, it looks like it has some sort of firewall with the Anti-virus 2009. Hard to tell though.

Do you need it? Well, we can't answer that for you. You have to decide what level of risk you are willing to accept. Is there anything on your computer that you don't want to be freely available on the internet? That might seem a bit severe, but we don't plan for the simple and easy stuff. Sure it will block a virus, but what if some flaw in vista is found next year that allows someone on the outside to access your C:\\. Maybe a firewall would mitigate this attack. I dunno.

If you don't want to run a firewall, then don't. I know my Comodo annoys the hell out of me but I put up with it. I spent about 4 years without anti-virus, firewall, or anti-spyware and I never had any problems. /shrug

The new 2009 norton stuff is very good, its no where near the same as it was before, as for a software firewall, well you could probably get away without having one, if you are behind a router which uses a NAT firewall. The only real reason for a software firewall is to prevent things from leaving your pc (i.e. keyloggers, malware) the incoming stuff is blocked by the router.

Windows Defender is not a firewall. its for spyware and such.


if you have a router then you really dont need a firewall. they usually have one built in.

These guys do a good job testing software firewalls. There are some really good free tools out there.

Well I think my answer was clear, but I'll try to explain it a little better, if you have a router, it will prevent any unauthorized traffic from entering your network from the outside using network address translation (NAT). However they allow unlimited out going traffic as long as it is initiated from inside your LAN. So the router has no way to tell what is coming out from your pc, it only blocks things that come from the outside (WAN). So if you are not worried about spyware and trojans on your machine sending stuff out to the net, then you don't need a software firewall. Basically all a software firewall does is prevent stuff from leaving your pc, like keygens sending out cc info etc. They usually leave standard ports open like 80 for web browsing, 21 for ftp etc. If you have games or apps that need different ports you can manually specify which ports need to be opened so the firewall won't block them. However if you don't do any file sharing or browse bad sites you can probably get away without having one.

Are you kidding me? I just spent an hour trying to remove it from my wife's new laptop.

IMO Norton is just as bad as any virus

Software firewalls are completely unnecessary and simply marketed to prey on people's fear. In the 15 years I've been using computers, I've never used a 3rd party software firewall. And you know how many viruses or other forms of malware I've gotten? None.

My bad...I stand corrected. The Windows Firewall is separate from Defender.
