Computer virus is a malicious program, which has the ability to replicate and execute itself. An antivirus software is a computer program used to scan files. It detects, prevents, identifies and eliminates computer viruses and other malicious softwares.

Antivirus is a kind of software used to prevent, scan, detect and delete viruses from a computer. Once installed, most antivirus software runs automatically in the background to provide real-time protection against virus attacks.

Antivirus is a program that is created to search, detect, prevent, and remove software viruses from your system that can harm your system. Anti Malware is software designed for scanning, detecting, blocking, and preventing malicious programs from accessing our system.

The terms malware and virus are often used interchangeably because they have significant overlap. A virus is a specific type of malware, but malware is a general term that also includes many types of malicious software that lack viruses' ability to self-replicate.

Malignant computer programs are often called viruses because they share some of the traits of biological viruses. The computer virus requires a functioning “host machine” to replicate, works only with the proper “host,” and passes from computer to computer like a biological virus passes from person to person.

An antivirus product is a program designed to detect and remove viruses and other kinds of malicious software from your computer or laptop. Malicious software - known as malware - is code that can harm your computers and laptops, and the data on them.

Virus. Viruses are microscopic organisms that can infect hosts, like humans, plants or animals. They're a small piece of genetic information (DNA or RNA) inside of a protective shell (capsid). Some viruses also have an envelope.

Antivirus programs use signature detection to look for specific pieces of code that are found in known viruses in order to contain and remove them. Signature detection is a core component of most antivirus software, but it's reactive – a virus must be known for its signature to be added to antivirus software.

Broader scope: Anti-malware software usually has a broader scope than antivirus software. It's designed to detect and remove a wide range of malicious software beyond just viruses, and often includes specialized features like email scanning, additional firewalls, and even password protection.

Antivirus software is designed primarily to prevent infection, but also includes the ability to remove malware from an infected computer. Stand-alone malware remover provides a convenient way of finding and removing malware from a computer or device in case the product already installed is unable to do so.

A virus is a computer program that can replicate itself and infect your computer. Antivirus software is used to prevent, detect, and remove malware like computer viruses, worms, spyware, Trojan horses, adware, and spyware.

What is the difference between malware and a virus? All viruses are malware, but malware can also include threats like spyware, ransomware, and worms.

Yes, antivirus software can remove some existing viruses. Antivirus software is typically designed to prevent your device from getting a virus, so you need to know what features come with the security software. If you want to know how to remove existing viruses, running an antivirus scan is your first step.

00:00. A virus is an infectious microbe consisting of a segment of nucleic acid (either DNA or RNA) surrounded by a protein coat. A virus cannot replicate alone; instead, it must infect cells and use components of the host cell to make copies of itself.
