ILOVEYOU is one of the most well-known and destructive viruses of all time. It’s been 15 years since ILOVEYOU was let loose on the internet. By today’s standards it’s a pretty tame virus, but in 2000 it was the most damaging malware event of all time. Likely, ILOVEYOU inspired many hackers to wield their keyboard as a weapon.Fred Cohen, who published one of the first academic papers on computer viruses in 1984,began to develop strategies for antivirus software in 1988 that were picked up and continued by later antivirus software developers. In 1987, he published a demonstration that there is no algorithm that can perfectly detect all possible viruses.The term computer virus, coined by Fred Cohen in 1985, is a misnomer.
Here's a quick sample of some famous viruses that had time triggers: The Jerusalem virus activated every Friday the 13th to destroy data on the victim computer's hard drive The Michelangelo virus activated on March 6, 1992 -- Michelangelo was born on March 6, 1475.
Computer virus history. The first true computer virus was Elk Cloner, developed in 1982 by fifteen-year-old Richard Skrenta as a prank. Elk Cloner was an Apple II boot sector virus that could jump.
Malware and security Malware is a general term that describes lots of different programs that try to do something unwanted to your computer. Anti-virus software prevents malware from attacking.
Computer virus, a portion of a program code that has been designed to furtively copy itself into other such codes or computer files. It is usually created by a prankster or vandal to effect a nonutilitarian result or to destroy data and program code. A virus consists of a set of instructions that.

Do you know that the first generation of computers used vacuum tubes for processing? This trivia questions quiz will help you refresh your memory on how far computers have come since then.
Virus - Virus - Evolution of new virus strains: Viruses that infect animals can jump from one species to another, causing a new, usually severe disease in the new host. For example, in 2003 a virus in the Coronaviridae family jumped from an animal reservoir, believed to be horseshoe bats, to humans, causing a highly pathogenic disease in humans called severe acute respiratory syndrome (SARS).
The Stuxnet virus is widely reported in the media due to attacks centered in Iran. The virus attempted to damage uranium enrichment centrifuges used in Iran’s nuclear development program by causing damaging speed variations. Although it was recognized that some centrifuges were rendered inoperable by the virus, the full extent of the damage.
The first computer virus was created on an Apple II computer in 1981, by a 9th grader. Richard Skrenta was that smart and mischievous 9th grader who knew a lot about computers. He first wrote code on his friends’ pirated computer games (on floppy disks, well before the unified internet) to prank them.
A computer virus, much like a flu virus, is designed to spread from host to host and has the ability to replicate itself. Similarly, in the same way that flu viruses cannot reproduce without a host cell, computer viruses cannot reproduce and spread without programming such as a file or document.
A computer virus is a program that is able to copy itself when it is run. Very often, computer viruses are run as a part of other programs. Biological viruses also work that way, as they copy themselves as part of other organisms.This is how the computer virus got its name. In addition to copying itself, a computer virus can also execute instructions that cause harm.
