There are tens of thousands of macro virus is floating around in the internet and they can be picked up very easily with the simple opening of a document. Once the document opens and the system becomes infected then all documents created there after are infected. The user inadvertently will pass the macro virus on to everyone who belongs to the network.

The second type of virus occurs when you open an email attachment. The attachment contaminated destroys your system and all the files that you created. Knowing how the virus works helps you to be able to combat any virus but what about the newly created virus. The ability to keep your system safe and secure depends on the programs that you use to fight any virus that may come your way. It also depends on how careful the user tries to be when opening programs. We are now going to present scenario of computer virus that explains how a computer virus may take place and then spread to others in the network.

Jane who is a freelance writer obtains all her articles from one source then she passes the assignments on to her network for completion. The supervisor Greg received a large group of assignments from a new client and in haste forwarded them on to Jane without opening or checking for any virus. Greg gave the instructions that he was about to leave for vacation and Jane would now take over, however, before distributing the assignments please open assignment B-12 and complete returning it instantly. It seems that the new client was desperate for a short blogs in order to open up his new website. The new client not being familiar with the use of anti-virus programs or personal a hacker had compromised firewalls and this particular request contained a very dangerous virus.

Jane trusting that Greg had checked the article for a virus and knowing the urgency opened the article request and began creating a 200-word document for the new client. When the document was completed, she forwarded a copy to Greg and to the new client. Jane then downloaded all the requests formatted them, divided them into categories and sent them on to those who were in her network.

When Jane created a new document in her excel program to enable her to be able to track the assignments this document became contaminated from the 200-word document she created previously. Jane now had a ticking bomb in her system but not a clue what was about to happen. Jane made the assignments to everyone in her network passing on their work sheet to enable them to receive assignments and returned completed for payment.

Each person in her network now had the virus. Jane had a network that consisted of twelve writers each of these writers had their own network of about six more writers. The first twelve writers were able to infect about 72 more writers plus friends and family members that they emailed on a daily or weekly basis. The number infected spread in a matter of hours losing count by the time the virus had become full-blown destroying systems, documents, and networks. The problem had to be contained and the person who spread this virus stopped. Naturally, no one expected Jane or Greg not even Jane and Greg.

Greg returned from vacation fresh and relaxed ready to begin. He opened up the emails sent to him by each of his providers, which numbered about 100. When Greg opened his emails and responded to each of the 100 people in his network and they in turn responded to their people you could see the terrible act that the whole network now faced.
