Computer Viruses Overview
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 its 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​ bootsector 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 bestknown 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​ fastinfector that possessed the​ capability to​ infect new files despite the​ presence of​ antivirus 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​ antivirus products began to​ rise. the​ threat of​ computer viruses was finally taken seriously. McAfee,​ IBM,​ Digital Dispatch and Iris all introduced their antivirus products and software in​ 1990. Despite their efforts,​ computer viruses grew faster,​ stronger and sneakier. Symantec Norton antivirus was introduced was introduced in​ 1991.
The introduction of​ Windows 95 brought both relief and discomfort to​ antivirus companies when it​ was released in​ 1995. at​ that time,​ most common computer viruses were still boot viruses that worked on​ DOS,​ but couldnt replicate on​ Windows 95. Then micro viruses were discovered in​ late 1995. These computer viruses performed in​ the​ MSWord environment,​ rather than DOS. Again,​ the​ antivirus 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 networktodo 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 email 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 email. When the​ receiver opened the​ attachment,​ the​ virus was automatically sent to​ everyone in​ the​ users 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​ antivirus programs.
Like people,​ getting sick is​ an unfortunate fact of​ life for computers. Using uptodate antivirus software is​ a​ sort of​ preventative medicine,​ helping to​ keep computers healthy and computer viruses at​ bay.
