i'm not using any firewall at all... its slows down my laptop and that irritates me.. is it really important to use a firewall??

I currently use the default windows firewall and windows defender in VISTA. But the best firewall is COMODO. Never let anyone down. works like charm and its FREE too.

Kaspersky firewall gives a lot of problem so i switch it off.

I am using Windows firewall for both of my operating systems and I haven't faced any trouble since past three years(three years on windows XP)
I have tried some free firewalls like Zone alarm but I could not carry on with those applications because of some drawbacks over each other so I preferred to have window firewall only and now working very smoothly....

well me..i have disabled the windows fire wall and i'm using Comodo personal firewall...It's Free for personal use and it's really nice...Have been using this since the last 1 year and have never faced any problems...

BTW i advise everyone not to go for Zone alarm

Well, I feel the Windows Firewall is best for Personal Computers. I have it as well as Panda Firewall running simultaneously. However, some of these firewalls may pose as a nuisance to many of the users in many ways. I feel, a computer is protected well enough if it has Windows Firewall enabled.

Right now i'm using windows default one which comes along with SP2. i'm just using it for surfing and for chichat so i think i don't need any personal firewall.

Basically there are two good and free firewall. These two are:
1) comodo firewall
2) Zone alarm free firewall.

Both are very good, but I will give +1 to comodo firewall. It is great firewall, and even better than many paid firewall. I am using it for more than 2 years, and well satisfied with it.

I am using Nod32 antivirus wich has incorporated a firewall.

i use the windows firewall which comes pre loaded with XP
secondly my ISP has installed a firewall (i dont know which)
therefore double protection for my PC

Well, I used Mcafee and Norton firewall before. But I am afraid that using two programs at one time may cause conflict to my computer. So at the time being I stick with Norton.

i use zonealarm free firewall for security purposes. it's lite and easy and great for protecting against hackers and all that stuff! :)
