Check how good your firewall (firewall) is securely
protected computer from intruders.
What is a Firewall?
Firewall can be translated to English means a burning
wall (fire - fire, wall - a wall), and you can often find the name of the
firewall (firewall is a designation only in Russian letters) or Brandmauer it
in German it means the same thing (brand - burn, mauer - Wall ), most often

Imagine that your computer is your apartment. The
apartment has windows and doors. I am sure that all windows and doors you keep
under lock and key and I do not think you would be happy if every passer-by
could come to you through an open door or climb through an open window.
By
analogy, you might be interested in the fact that no stranger could not just
log into your computer and take what he wants or what ever remove your
important data.
On windows and doors have locks of your home, you lock
them and feel safe. If you need to get out or let in to my friend, you open the
door and lets you or release the right people. By installing a firewall, you
can configure it so that he missed out on the Internet or run from the Internet
only to those programs that you let him. Everything else will be blocked as the
input and output.
In fact, you put a filter between your computer and the
Internet, which allows only a necessary and important to you, everything else
is filtered.

firewall and that is in the network is not infected by a maximum of 2 minutes.
After this time you will definitely get his share of malware.
