Many computer users adopt the ‘it will never happen to me’ policy, but there are a number of computer viruses out there just waiting to infect and destroy the information contained on their hard-drive. This is why companies invented anti-virus software, which is a program that automatically helps to detect the presence of viruses on a computer or in a file before it is opened.

Anyone who spends a considerable amount of time surfing the internet, visiting unfamiliar websites or downloading photographs is at a higher risk for computer viruses than those who do not. Computer viruses are typically attached to word processing documents, computer programs and images which, if downloaded, may instantly affect the computer’s performance.

If a computer virus infects a computer, the owner may immediately lose everything in their computer and may be forced to use the factory restore disk. This CD, which is accompanied by most new computers, will restore the computer to it’s original factory settings.

Anti-virus software is quite affordable considering it’s wealth of use. Without it, computer users are at constant risk for computer viruses. Anti-virus software can generally be found at any computer manufacturer’s website, retail store’s electronic department or online at many retailers selling computers.

Anyone who suspects that their computer may be infected with a virus should refrain from sending any e-mail messages or uploading photos to family or friends. Otherwise, the virus may spread to infect their computers as well.

Sample of Improvement

This site is proof that Spanish speakers now have more options than they ever had before. This site can be found similar to other sites that feature sports and games information. After comparing them with other sites that offer similar information, I find very little difference. In fact, the layout looks suspiciously similar except that the main advertisements on the home page on games and sports are probably those that they sponsor. Each ad comes with descriptions about a line or two long. At least, they do not crowd the main page but gives the user enough time to take in the information without straining his eyes.

Neat Graphics

Web and FTP Servers

Every network that has an internet connection is at risk of being compromised. Whilst there are several steps that you can take to secure your LAN, the only real solution is to close your LAN to incoming traffic, and restrict outgoing traffic.

However some services such as web or FTP servers require incoming connections. If you require these services you will need to consider whether it is essential that these servers are part of the LAN, or whether they can be placed in a physically separate network known as a DMZ (or demilitarised zone if you prefer its proper name). Ideally all servers in the DMZ will be stand alone servers, with unique logons and passwords for each server. If you require a backup server for machines within the DMZ then you should acquire a dedicated machine and keep the backup solution separate from the LAN backup solution.

The DMZ will come directly off the firewall, which means that there are two routes in and out of the DMZ, traffic to and from the internet, and traffic to and from the LAN. Traffic between the DMZ and your LAN would be treated totally separately to traffic between your DMZ and the Internet. Incoming traffic from the internet would be routed directly to your DMZ.
Therefore if any hacker where to compromise a machine within the DMZ, then the only network they would have access to would be the DMZ. The hacker would have little or no access to the LAN. It would also be the case that any virus infection or other security compromise within the LAN would not be able to migrate to the DMZ.

In order for the DMZ to be effective, you will have to keep the traffic between the LAN and the DMZ to a minimum. In the majority of cases, the only traffic required between the LAN and the DMZ is FTP. If you do not have physical access to the servers, you will also need some sort of remote management protocol such as terminal services or VNC.
