When we connect our computer to a
private LAN or
Internet, we open a door to the exterior that can be used by hackers to attack us or steal our private details.
To fight against this type of threats we have
firewalls. This type of tool control all the
incoming and outgoing connections of our PC, keeping us informed of all of them and avoiding the one that start and we don't want.
Before the Windows systems and the majority of antivirus included firewalls,
ZoneAlarm Free became popular as a competent security server with a user friendly interface, that to improve it was completely
free.
ZoneAlarm Free is still one of the best firewalls that exists. The little brother of the protection products developed by ZoneAlarm doesn't include an antivirus nor antispyware functions, centering all its power in detecting and blocking strange connections.
If you complement this application with one of the
free antivirus and antispyware programs that we can find in Internet, we can achieve the
same protection levels we would have with a paying solution.
As a firewall application, it has as many options available and the same efficiency of even the most expensive programs on the market, allowing us to establish all kinds of rules by means of a friendly interface.
It capacity to control our
email is very interesting, because it can avoid a bot from sending unwanted mail to any of our friends without our permission.
One of the best existing firewalls, and to improve it, its
completely free.
