But the actual truth is that computer viruses have been around for longer than most people might think. This virus, which spread via floppy disks, was known only to infect boot records and not computer hard drives like most viruses today.

The virus also known as the Lahore, Pakistani, Pakistani Brain, Brain-A and UIUC would occupy unused space on the floppy disk so that it could not be used and would hide from detection. It would also disguise itself by displaying the uninfected bootsector on the disk. The Lehigh virus was the first memory resident file infector that attacked executable files and took control when a file was opened.

The Jerusalem virus also appeared around this time at Hebrew University in Israel. Like the Lehigh virus, the Jerusalem virus was also a memory resident file infector. It contained bugs to re-infect programs that were already infected. In Marchthe first anti-virus was designed to detect and remove the Brain virus.

The anti-virus also immunized floppy disks to get rid of the Brian infection. At the same time, the Cascade virus appeared in Germany.

The Cascade virus was the first encrypted virus, which was coded and could not be changed or removed. Magazines such a Business Week, Newsweek, Fortune, PC magazine, and Time began publishing articles about these destructive viruses running wild and demanded a solution for all these problems.

InSymantec released the Norton Anti-virus software. Hence, viruses are still common and still create chaos even today. It is hard to determine the reasons for all these actions and why virus writers create computer viruses.

Some do it for their personal gain, for research projects, pranks, vandalism, etc.Computer viruses can be vicious little blighters wreaking all sorts of damage and destruction; destroying files, corrupting hard drives, plundering personal details and slowing the Internet to a crawl. A computer virus is a type of malicious software that, when executed, replicates itself by modifying other computer programs and inserting its own code.

When this replication succeeds, the affected areas are then said to be "infected" with a computer virus. Sep 04,  · Computer Viruses are actually just one type of malware, a self-replicating programs designed to spread itself from computer to computer.

A virus is, in fact, the earliest known malware invented. The following is a history of some of the most famous viruses and malware ever:3/5(4).

A Brief History of Computer Viruses & What the Future Holds When it comes to cybersecurity, there are few terms with more name recognition than "computer viruses." Despite the prevalence of these threats and their wide-spread impact, however, many users don't know about the basic nature of viruses.

When talking about the most expensive computer viruses of all times its important to understand that from time to time the cyberspace experiences different security challenges. Computer viruses are just one kind of online threat, but they're arguably the best known of the bunch. Computer viruses have been around for many years.
