An Outline Of Computer Virus Issues

Computers have incredible capabilities. They can accomplish great tasks, communicate clearly, make things move and think beyond human measure. Computers have become like humans in nearly every conceivable manner, so it’s no surprise that computers can also get sick.

The computer revolution first began picking up speed in the late 1980s. Since then, it has evolved to be a vital element in our society, our corporate and our personal lives. Computers have become part and parcel to virtually everything we do day in, and day out. But with all good comes a little bad. Some users have maliciously created computer viruses that have grave effects. The range of computer viruses existing in our modern networks has a huge prominence in our lives, because of all the ways we depend on computers. Despite our need for dependable computers, some people have nothing better to do but exercise their computer knowledge in a destructive way, creating computer viruses.

The first computer virus, called “The Brain”, was created in 1986. The Brain is a boot-sector virus, which occupies unused space on the disk to eliminate further use of memory space. After it was created, The Brain quickly spread worldwide in 1987. The Brain virus was considered first to use stealth techniques, making the virus difficult to detect.

On November 1, 1987 another virus appeared. The Lehigh virus was named after Lehigh University, the place where this particular virus was first discovered. One Friday the thirteenth, in December of that same year, the Jerusalem virus was discovered at Hebrew University. This virus has also gone by the names “ArabStar”, “Friday the 13th” and the “Black Window”. This is one of the oldest and best-known computer viruses in the world.

Two more viruses surfaced in 1988: the Stone, which was the first bootstrap virus, and the Internet Worm. The Internet Worm caused mayhem in the corporate world as it crossed the United States overnight through a series of computer networks. Then in 1989, the Dark Avenger was introduced. This was a fast-infector that possessed the capability to infect new files despite the presence of anti-virus software. The Dark Avenger computer virus was designed to damage a system slowly. The virus would go unnoticed at first, and damaged files would not be backed up. Slowly it would consume more and more of your computer until it had created permanent damage.

Computer manufacturers and software engineers began the public war against computer viruses around 1990. Corporations began to respond to growing public concern and the number of anti-virus products began to rise. The threat of computer viruses was finally taken seriously. McAfee, IBM, Digital Dispatch and Iris all introduced their anti-virus products and software in 1990. Despite their efforts, computer viruses grew faster, stronger and sneakier. Symantec Norton anti-virus was introduced was introduced in 1991.

The introduction of Windows 95 brought both relief and discomfort to anti-virus companies when it was released in 1995. At that time, most common computer viruses were still boot viruses that worked on DOS, but couldn’t replicate on Windows 95. Then micro viruses were discovered in late 1995. These computer viruses performed in the MS-Word environment, rather than DOS. Again, the anti-virus industry faced challenges to fight against these new batches of viruses. With the introduction and growing popularity of the Internet in the late 1990s, viruses began to spread at a much faster rate.

Throughout 1998 there was no lessening of computer virus attacks MS Office, MS Windows, MS Office and network applications. New viruses continued to appear, and computers and advanced network-to-do applications continued to be affected. In 1999, another virus appeared, infecting computers using Microsoft Word. This computer virus may have been passed on via MS Outlook, or through Outlook Express e-mail programs.

The “Loveletter” virus, also known as “Love Bug” and the “I Love You” virus, is believed to have struck one in five PCs worldwide, making it the most widespread and the most costly computer virus the world had ever seen. The “I Love You Virus” created panic and discord around the globe. The virus was transferred by e-mail. When the receiver opened the attachment, the virus was automatically sent to everyone in the user’s address book. The “I Love You” computer virus spread at a dizzying rate of speed.

As long as we continue to use the Internet and share computer files, we are at risk of catching computer viruses. Even today, more and more viruses are still being discovered, leading to big problems for all users, and creating ongoing dilemmas for the creators of anti-virus programs.

Like people, getting sick is an unfortunate fact of life for computers. Using up-to-date anti-virus software is a sort of preventative medicine, helping to keep computers healthy and computer viruses at bay.

How Computers Have Revolutionized Our World

Personal Computer

Personal Computer

The world has been completely changed by the advent of personal computers. This is because they have radically transformed the way the world lives, works and conducts business. Computers actually arrived on the scene back in the 1930s and were the brainchild of one Konrad Zuse who produced what was then called the Z1 computer. While this was a giant innovation, this was far from the sophisticated machines that we have today.
That computer laid the groundwork for further research by others. In 1944, two men named John Atanasoff and Clifford Berry from Iowa University produced several innovations of the computer based on Zuse’s model. It was capable of producing simple to moderately complex arithmetic calculations and small but simple computing tasks.
Harvard University, then took it a notch higher and partnered with IBM, the business conglomerate in 1953 to produce what was then the world’s first sophisticated computer. Even then, computers were still gigantic and occupied huge spaces and used a lot of power.
The world as we know it today has been completely changed by computers. They now sit in almost every office space in most major cities of the world. It is hard to imagine business as we know it today without computers. Work would be grossly inefficient and cumbersome. Take for example calculations. It would not be possible for companies which hold a lot of material and inventory to process orders efficiently without computer power.
Computers have also made a giant impact in the field of communication. With the advent of the Internet, the World Wide Web or Information Superhighway, the world has become smaller and has even been referred to as a global village. Phrases such as “global market place” have also been coined to signify how computers have been able to link the world.
We mentioned communications and how computers have made a giant impact in this realm. Messages can now be sent and received via email instantaneously from one end of the globe to the other. This has almost rendered the regular snail mail obsolete. Then there are chat rooms, Instant Messaging and Video Messaging which have transformed the way people meet and interact across the globe.
All this has been made possible by computers connected to the Internet via wireless and wired networks. Large firms such as Microsoft, Yahoo and Google have contributed to this by running sophisticated web applications that have made it possible to chat in real time with someone on the other side of the globe. This has completely changed the way we conduct meetings and even run classrooms and training.
Businesses have benefitted tremendously owing to the advent computers. Companies can even open virtual branches in other countries without necessarily being there physically. Banks can even run on the Internet without possessing actual premises. Such has been the impact of computers to modern life. Sometimes they also have their own disadvantages in that some people accuse them of causing some to be thoroughly anti-social. It is also easy for some to develop multiple identities online to mask their true selves.
