It was a virus for Macs written in 1982 by a high school student named Rich. but another on of the first type was a worm called the creeper worm was created as an experimental virus by Bob Thomas in 1971. It infected PDP-11 systems. the leader of the Internet in the early 1970. Creeper was an experimental self replicating program Designed. Creeper used the Arpanet to infect PDP-10 computers running the Tenex os. Creeper got access via the Arpanet and replicated itself to the a remote system. but there r many different opinions on this factor.

History on viruses? I am going to go over the history of computer viruses in 1945 Grace Murray Hopper was the first to discover a moth trapped between two switches in a Navy computer. She calls it a bug which is the term used nowadays since the late 19 century to refer to problems with electrical systems. Murray Hopper was also the one to helped name a computer bug a computer bug. The typical viruses common to us now came to are ayes in the 1980s when a computer system runs programs that allows users to dial into the internet over a phone line or modem. In 1990 a new virus was brought to our eyes it was called a micro virus. Microsoft Word was a program that allowed the macro virus to multiply and gain blank information. This can cause major problems to a system. but today it is a lot harder to get rid of viruses with any portion of technology but the new fastest virus is called the Virus.Win32.Virut according to a recent studies an reports. This virus is very good at injecting itself into software of files on a computer on your computer in such a way that it is difficult to remove.

But these viruses can do any kind of damage it wants to a PC. They are a program that pretends to do something when they are really doing allot damage to that program that it is running on when the user starts it that's when it infects. Trojan attacks are one of the most dangerous threats of all so these types of viruses can be spread in literally everything. Which makes it almost impossible to notes when you are looking for them? The worm is the most common types of computer viruses these also work by using a computer networks and security to be able to create copies of itself via tracking ip addresses and then copying the same worms and it will continue to scan all the ips till it infects the computer network for any other security Problems. Worms are definitely more defined than Trojan viruses and a computer worm does not need a program run it is able to infect and replicate of its self. When ever and ware ever it wants to or sees a computer hole in security.
