Use a firewall

Use a firewall

A firewall is a security unit that keeps people from taking control of your PC.

It is especially useful for people with a permanent DSL connection, cable modem or dial-up access (temporary connection or remote hookup to a network).

Computer barriers like this are practically impossible to penetrate, which is why for the most part, thieves try to get a hold of access codes and passwords.

Make sure that your operating system firewall is activated or that your antivirus software allows for firewalls.
