What is antivirus let's know?
Antivirus Software is a data security utility which is installed in a computer system with a purpose of protection from viruses, spyware, malware, rootkits, Trojans, phishing attacks, spam attack, and other online cyber threats.
Let’s know a bit about the Virus.
A virus is any unwanted program that enters a user’s system without their knowledge. It can self-replicate and spread. It performs unwanted and malicious actions that end up affecting the system’s performance and user’s data/files. A computer virus can be thought of as an illness of the computer, just like human viruses that cause diseases in humans.
And what about Antivirus?
An antivirus software, as the name indicates, is a program that works against a virus. It detects or recognizes the virus, and then after detecting the presence of the virus, it works on removing it from the computer system. Antivirus software works as a prophylactic so that it not only eliminates a virus but also prevents any potential virus from infecting your computer in the future.
A system without an antivirus is just like a house with an open door. An open and unprotected door will attract all the intruders and burglars into your home. Similarly, an unprotected computer will end up inviting all the viruses to the system. An antivirus will act as a closed door with a security guard for your computer fending off all the malicious intruding viruses. So, will you leave your door open for intruders?
