Why Do You Really Need A Firewall? Together with antivirus and antispyware, it is a "must" to protect your PC. Firewalls protect you from many Internet hazards. Be alert, the bad guys can get pretty creative at what they are launching. Here are some rather frightening examples of what might be coming your way. But remember as with all antimalware, your protection is totally based on your own diligence, and that is why firewalls are so important because they do protect your computer. Here are some examples:
Remote login - Allows someone to connect to your computer and control it, look at files and run programs
Backdoors - Some programs you may have downloaded could have hidden features that allow for remote access. Many others contain bugs that allow outside control of your PC
Mail hijacking - Taking over your contact list and using your computer to send out spam.
Now you just might think, Windows XP has a firewall, why don't I just use that? Good idea but you need more oomph. The firewall built into Windows XP could be called 'firewall lite'. It's pretty bare bones. For instance, it does not block outgoing traffic! In other words, it allows your confidential information straight out to the Internet (you get what you pay for). Utilizing a full personal firewall gives you a lot more control and defensive fire power.
