What is the Meaning of Virus (computer science) | Definition and Concepts
One of the first symptoms that a virus we have is that the operating system begins to have errors, now would be a good idea to let your antivirus to do a scan in depth of our PC. Operating systems such as windows xp are particularly vulnerable, due to lack of support from Microsoft. Computer viruses are a very appropriate name, since they emulate quite well what makes a virus in the human body: first, infecting it and then kill you or make you chronically sick. This computer would translate as: first, the infected machine and then let it worn out completely, do not load the operating system or causing to go slow and be very difficult to manage.
A computer virus is actually a program that is slowly making changes in vital systems from the operating system to have full control of the computer. There are cases in which when a virus takes control of your computer, the virus calls for amounts of money to the person owner of the infected computer to release valuable files, for example, a company.
The solution is an antivirus, this solution is sometimes a problem especially when our machine it is a little old and we see that after installing the anti-virus computer is a bit slow. Before you pay for an antivirus solution, it is advisable to try a demo of the program and see how it will respond to our system.
There is some confusion with regard to viruses and worms, the latter are intended to replicate if same and sent via the internet to infect other computers on the network. The worms were in fact the reason for the creation of the firewall.
Making a little history of the virus, the first was created in 1972, sent a message on the screen at certain intervals of time saying "I am an enredadora, catch me if you can". The answer was the first antivirus called 'cutter' English reaper. Be the term adopted virus there by 1984, although the first virus of all those who have been around, was developed much earlier by four programmers of Bell Labs. They developed a game called Core War, game consisted of filling the RAM memory of the opposite in the shortest possible time, with what the opposite computer was useless and I had to restart.
A virus is spread when the user runs a program and the virus is contained in this program. The basic function of a virus to infect, destroy and spread, not always in that order. Some people may feel that having two antivirus will be more secure but with two antivirus at the system only they were successful in that the system slows down to the limits in our machine is virtually useless for work.
