What is a Computer Virus and How Can I Protect My Computer?
Secure your endpoints and servers with industry-leading protection, detection, and response solutions. A computer virus is malware attached to another program such as a document , which can replicate and spread after an initial execution on a target system where human interaction is required. Many viruses are harmful and can destroy data, slow down system resources, and log keystrokes. Cybersecurity Basics. Computer virus. Most computer viruses target systems running Microsoft Windows.

What is a computer virus? A computer virus is a small software program that spreads from one computer to another and interferes with computer operation. A computer virus might corrupt or delete data on a computer, use an email program to spread the virus to other computers, or even delete everything on the hard disk. Computer viruses are frequently spread by attachments in email messages or by instant messaging messages. Therefore, you must never open an email attachment unless you know who sent the message or you are expecting the email attachment.
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. In order for a virus to infect your computer, you have to run the infected program, which in turn causes the virus code to be executed.
Social implications – The society will also benefit by attaining knowledge about the different types of computer viruses and the measures of.
9 types of malware and how to recognize them
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.
Computer virus – Virus protection & removal
People tend to play fast and loose with security terminology. However, it's important to get your malware classifications straight because knowing how various types of malware spread is vital to containing and removing them. This concise malware bestiary will help you get your malware terms right when you hang out with geeks. A computer virus is what most of the media and regular end-users call every malware program reported in the news.
A computer virus is a malicious piece of computer code designed to spread from device to device. A subset of malware, these self-copying threats are usually designed to damage a device or steal data. Think of a biological virus — the kind that makes you sick. A computer virus is very similar. Designed to replicate relentlessly, computer viruses infect your programs and files, alter the way your computer operates or stop it from working altogether. Some computer viruses are programmed to harm your computer by damaging programs, deleting files, or reformatting the hard drive.
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. The purpose of creating a computer virus is to infect vulnerable systems, gain admin control and steal user sensitive data. Hackers design computer viruses with malicious intent and prey on online users by tricking them. One of the ideal methods by which viruses spread is through emails — opening the attachment in the email, visiting an infected website, clicking on an executable file, or viewing an infected advertisement can cause the virus to spread to your system. Besides that, infections also spread while connecting with already infected removable storage devices, such as USB drives. It is quite easy and simple for the viruses to sneak into a computer by dodging the defense systems.
Computer viruses attack systems by tricking an authorized user into executing them. The virus infects other programs, and spreads throughout the system. Computer viruses are related to other types of programs such as Trojan horses and computer worms. These programs are forms of malicious logic.
