Windows XP has a built in Firewall. Turn it on. One free one is Zone Alarm if you are not running XP.
I have a very effective firewall on my computer that I downloaded for free from Sygate. It blocks any harmful computer viruses from coming in.
The best firewall software solely depends on a persons needs and price range. A good firewall software to use is Norton Antivirus, due to it being reasonably priced, offering free trials, and overall a good protector against computer viruses.
You have to use firewall. Windows firewall usually doesn't help in such case. You can find many free firewalls in internet.
The best free firewall is the one built on to most computers. Better firewalls cost a lot of money. Software that claim to be free and better than built-in firewalls are usually spam or malware.

CNET . Type in the combo box Comodo firewall and download for free.
You need to have a firewall installed on your computer. Activate the firewall that comes with windows, by clicking on it, in the control panel, or you also can get a free firewall, I use the free version of zone alarm. To find a free firewall, put "free firewall" into the google search engine, and many different ones will appear. You also need an antivirus program, again, you can get a free one online by the same method. I use the free version of AVG, which is a very good antivirus program. You can have 3 or 4 anti-spyware programs installed on your pc. I like windows defender (free) spybot-search and destroy, (free) online search will find more free ones. Remember, you can only have one anti-virus program, and one firewall installed on your computer, or they will conflict with each other. You should at least have two anti-spyware programs on your computer, and run them at least once a week. I hope this will help you, Good Luck..
The free version does not contain a firewall but you can use your windows firewall with it. You have to buy the full version if you want a firewall with the software. I found that Norton 360 is the best for me.
Some of the best free computer security options available are AVG Antivirus Free and Avast Free Antivirus. However, if you want complete protection with firewall and spyware protection included, you will most likely have to choose for the paid internet security suits.
First of all, ALWAYS have your firewall on, next, install avg free anti-virus, just Google it, youll find it, and just don't let any files you don't absolutely trust make changes to your computer. Your Welcome.
Yes. You at least need a firewall. Zone Alarm is an example of a firewall you can get for free.
