Antivirus programs are designed to protect your computer from malware, a term used to describe malicious software malicious software, including viruses, trojans and keyloggers, may delete your files, slow your computer and steal your personal data. This article's aim is to offer readers basic knowledge about computer viruses and confidence in protecting their computers an important thing to keep in mind is that viruses can infect anything in your computers at anywhere, anytime. 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.

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. What is a computer virus a computer virus is a piece of malicious code that adds itself to other existing programs, including operating systems computer viruses spread quickly and wreck havoc on. Computer viruses come in a variety of types breaking them into categories is not easy as many viruses have multiple characteristics and so would fall into multiple categories. In general, there are five main morphological virus types: viral structure: an outline of the structures of some common viral types helical – these viruses are composed of a single type of capsomer stacked around a central axis to form a helical structure, which may have a central cavity, or hollow tube.

A direct action virus is one of the two main types of file infector viruses (the other being a resident virus) the virus is considered “non-resident” it doesn’t install itself or remain hidden in your computer’s memory. There are many characteristics of viruses, which can be discussed here, but major characteristics of viruses are as follows: 1 viruses are extremely small infectious agents, which are only visible under electron microscope. Virus: like its living counterpart, a computer virus infects your computer, taking control over some or all of its functions the virus destroys data or looks for things like passwords, credit card numbers, or other sensitive data.

One of the characteristics of viruses is that they can infect other fungi, microbes, plants, animals and humans viruses that infect fungi are called mycophages, whereas bacteriophages are viruses that infect only bacteria 7 host range. A computer virus is a program that is unique and different from one another a virus can we know of its existence as easily as it causes the effect of which is easily known, but there are also viruses that effect is not seen directly but results in a very severe data damage. If a computer is infected with boot sector virus, when the computer is turned on, the virus launches immediately and is loaded into memory, enabling it to control the computer • file deleting viruses: a file deleting virus is designed to delete critical files which are the part of operating system or data files. The point of today's lesson, of course, is to help you teach your friends and family more about the different types of malware, and debunk a few of the common myths about viruses. A virus can live in two different phases – the lytic phase (where the virus actively replicates in a host cell) and the lysogenic phase (where the viral dna incorporate itself into the cell’s dna and multiples whenever the cell multiplies.

Computer viruses and their effects on your pc this page intentionally left blank table of contents what is a virus 1 how a virus infects your system: 2 how does a virus spread 3 biggest myth: i buy all of my programs on cd rom from the store store bought software never contains viruses. A trojan or trojan horse is a non-self-replicating malicious program that often disguises itself as legitimate software while some trojans have the same payloads as viruses and worms, others open backdoor ports to allow crackers access to a remote computer and to cause the computer download programs without the user's consent. Another enveloped virus, the influenza virus, is engulfed by the cell some non-enveloped viruses, such as the polio virus, create a porous channel of entry and burrow through the membrane. Despite being categorized as the simplest microbes, the characteristics of viruses are very distinct from other microorganisms be it size, genomic content or reproduction, viruses are characterized with unique attributes.

  • A computer virus has 2 major characteristics: the ability to replicate itself, and the ability to attach itself to another computer file every file or program that becomes infected can also act as a virus itself, allowing it to spread to other files and computers.
  • This lesson details the impact of computer viruses and some of the most common types of viruses quiz & worksheet - characteristics of computer covers the financial cost of dealing with.
  • When a virus encounters a cell, a series of chemical reactions occur that lead to the production of new viruses these steps are completely passive, that is, they are predefined by the nature of the molecules that comprise the virus particle.

The main purpose of antivirus software is, of course, to protect the computer from getting a virus it does this by scanning downloads and attachments for viruses, and by running in the background when the user is surfing the internet. Blended threats combine the characteristics of viruses, worms, trojan horses, and malicious code with server and internet vulnerabilities to initiate, transmit, and spread an attack by using multiple methods and techniques, blended threats can rapidly spread and cause widespread damage. The damage caused by a virus can vary, affecting your personal computer as well as overloading email servers and networks in order to protect your devices from infection, it is important to understand the characteristics of virus emails and hoaxes, and the importance of updating the anti- virus software installed on your devices on a regular. Computer virus is a malicious software program “malware” that can infect a computer by modifying or deleting data files, boot sector of a hard disk drive or cases a software program to work in an unexpected manner.
