About Securing Economical Application on our System by Protecting our Computer from Intruders

Computer security is one of the most important issues in the computer world. With the number of viruses and other malicious software that prey on exploits in the Windows operating system increasing, we need to take preventative measures to make sure that our computer does not become infected. The days of only having to worry about e-mail attachments and documents on a floppy disk are over. Nowadays, viruses or worms actively seek out computers to infect without the computer user even doing anything. Once a virus or worm has gained entry to a system, the invaded computer can turn into a virus distribution centre. Often, the computer sends copies of the virus to all of the people in its address book. Even worse, the infected computer may begin to scan a block of IP addresses (that is, computer addresses) to try to find more machines that it can infect.
