The term "computer virus" is used to describe a computer program that can be replicated and infect a computer. Like its namesake, the biological virus, a computer virus must rely on the user of one computer to spread it to another computer. Download Norton Security Setup.
Even though the conditions have become somewhat interchangeable , specifically by personal computer beginners , not every dangerous programs are infections , but a malware is a form of virus . A few creators can distribute a part of the malware to numerous computers , which is replicated while computer consumers involuntarily transfer the software , usually via infected emails.
Computer malware virus and non-viral malware
Two examples of the different between viruses & many types of malware are spyware & adware. Normally, these 2 types of malware are used to learn the patterns of use of individual PC users & report them to their creators so that they can benefit from the findings. In general, they are not intended to deliberately attack a computer, although it can be a side effect, & the user must not transfer them to other computers either.
Viruses , on the other side , are made to cause interruptions in regularly processes on as numerous computers as is possible with an executable program . Viruses is often as simple since several lines of text created as a practical joke , and as harmful as a program which could completely remove the material of a hard drive.
Computer Virus Today
Along with email and network viruses, current viruses can also be spread through portable USB drives. While this is an easy way to share files, especially in commercial environments, it can also detect viruses from unprotected computers and propagate them to every computer the owner uses with that unit.
Some people think that computer viruses are harmless, which is known as crime without victims, such as graffiti. However, like graffiti, it can cost time, effort and tons of money to remove viruses from a computer or from a complete network. It can also affect the flow of commerce, whether it freezes computers that operate in an online store, to a large company that has to extract resources from an area of ??their business to concentrate on cleaning or replacing damaged computers. When this happens, often a company will have to pass the cost of the damage to its consumers.
The Evolution of Computer Viruses
Academically, early theories of viral computer attacks were recognized as early as the late 1940. Then, in the 1970, Then , in the 1970 , the very first infections that were incorporate , usually as tests , were conducted in confined conditions. These early "attacks" , for example the Creeper malware , which only infected computer systems with a playful type of text , were essential , as they also assisted programmers discover ways to fight viruses .
In addition, he showed that the theories were correct, that it was possible for a person to invade a series of computers.
As the popularity of home computers increased in the 1980, so did the popularity of virus creation. Before the widespread use of the Internet, viruses were distributed more frequently on floppy disks, the support of disk-based operating systems, popular software titles and editable floppies purchased in the store. This was an easy method because all the software on diskettes (even those directly from the editor) was easy to modify and, therefore, easy to copy and share with friends. This specific method of spreading a virus almost gets in the way, since operating systems have increased in size and no longer fit on one disk, plus the fact that all software titles are now on CD or DVD, which can be done in a read only format
Prevention and Protection of Computer Viruses
There is no way to avoid creating viruses. There will always be a young programmer who wants to show that he can "play with the big guys" or a hacker who simply wants to see the chaos and the damage. And, like vandalism in the real world, someone who creates a virus can start his "career" with a harmless joke, but grow up to cause millions of dollars of damage by eliminating massive files from multiple corporations.
The best way to protect your home computers from viruses is to update your antivirus software, keep your computers and software updated with the latest patches, and monitor the behavior of all users of a computer, including the type of files that may contain viruses There will always be viruses, but staying alert will help prevent a computer from becoming infected.
