A firewall is a program that sits in between you and the
internet, it analyses incoming and outgoing traffic to try
to intercept threats to your security. It's mainly looking
for hacking attempts. As long as your internet connection is
open its like an open door to hackers. A good firewall will
make your pc invisible to most hackers. If they can't see
you they can't break in.
Its not foolproof, so an anti virus, an anti trojan, an anti
adware and an anti spyware are your next line of defence.
They scan everything on your system looking for malware (
malicious software) that is installed or running.
Some security programs have 'real time' scanning so also
watch for changes as they happen, like a firewall does.
You need a number of different security programs to deal
woth different problems. Here are some good freeware ones.
