A computer virus is not that different from a real-life virus like, say, the flu. When contracted, they can both remain dormant in the system only to become active when you least expect them to. If you detect the threat early and take appropriate measures on time, you will be able to keep the symptoms under control and recover very quickly.

A computer virus is a malicious program that self-replicates by copying itself to another program. In other words, the computer virus spreads by itself into other executable code or documents.
What is a Computer Virus?
Malware a portmanteau for malicious software is any software intentionally designed to cause damage to a computer , server , client , or computer network   by contrast, software that causes unintentional harm due to some deficiency is typically described as a software bug. Programs are also considered malware if they secretly act against the interests of the computer user. For example, at one point Sony music Compact discs silently installed a rootkit on purchasers' computers with the intention of preventing illicit copying, but which also reported on users' listening habits, and unintentionally created extra security vulnerabilities. A range of antivirus software , firewalls and other strategies are used to help protect against the introduction of malware, to help detect it if it is already present, and to recover from malware-associated malicious activity and attacks. Many early infectious programs, including the first Internet Worm , were written as experiments or pranks. Malware is sometimes used broadly against government or corporate websites to gather guarded information,  or to disrupt their operation in general.
The purpose of this paper is to discuss various types of computer viruses, along with their characteristics, working, effects on the computer systems and to suggest measures for detecting the virus infection in a computer system and to elaborate means of prevention. The author undertook an extensive study and review of the literature available online and on relevant web sites on the present topic. A large number of viruses were found during the study, which are causing serious damages to computer systems. The author suggests ways to detect and prevent the different computer viruses. The research is based on and limited to the study of the relevant literature available on different relevant web sites.
The dangers of malware are something you can't put lightly. After all, there is around , new malware developed every day. In any case, there are a lot of other things you need to worry about like receiving PC repair messages. But recognizing the types of computer viruses out there is vital if you want to maintain your computer's stability. When it comes to the ordinary user perspective, this type of virus is one of the most dangerous ones out there. Their infection spreads on the master boot record.
What is 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. In more technical terms, a computer virus is a type of malicious code or program written to alter the way a computer operates and is designed to spread from one computer to another. A virus operates by inserting or attaching itself to a legitimate program or document that supports macros in order to execute its code. In the process, a virus has the potential to cause unexpected or damaging effects, such as harming the system software by corrupting or destroying data. Once a virus has successfully attached to a program, file, or document, the virus will lie dormant until circumstances cause the computer or device to execute its code.
Computer viruses are a lot like biological ones. Once they find a suitable host, they can replicate themselves and spread their disease to others. Both types prey on weakened defense systems and the best way to fight them off is to render them non-infective and then build up immunity. For computers, the best way to do this is to periodically replace outdated antivirus software. To date, computer engineers have identified three major types of viruses, which can be further divided into many separate subcategories. They include:.
A virus is a computer code or program, which is capable of affecting your computer data badly by corrupting or destroying them. Computer virus has the tendency to make its duplicate copies at a swift pace, and also spread it across every folder and damage the data of your computer system. A computer virus is actually a malicious software program or "malware" that, when infecting your system, replicates itself by modifying other computer programs and inserting its own code. This is a computer program that replicates itself at a swift pace. Unlike a computer virus, it is self-contained and hence does not need to be part of another program to propagate itself.

No one enjoys being sick. It might sound silly, but your computer can catch a cold just like you. Doctors can usually diagnose a virus based on symptoms exhibited by the body. IT professionals can do the same with computers. Typical signs of computer virus infections include:.
Попробовал добрести до двери. Меган скрылась во вращающейся секции, таща за собой сумку. Беккер почти вслепую приближался к двери. - Подожди! - крикнул .
Она шагнула вперед, но и там была та же пустота. Сигналы продолжались. Источник их находился где-то совсем близко.

Пора. Она должна немедленно поговорить со Стратмором. Сьюзан осторожно приоткрыла дверь и посмотрела на глянцевую, почти зеркальную стену шифровалки.
