Do you really need to install Antivirus Protection?
The response to this question is "yes" without any hesitation, and there are several explanations why, namely:
Malware
Definition: Software that is specifically designed to disrupt, damage, or gain unauthorized access to a computer system.
Aftereffect:The biggest problem, by far, is that the most powerful forms of malware will quietly find its way into your Computer or smartphone without you knowing it's there. It will most likely lie dormant, hidden from view, but it can cause a number of different problems, which can affect you in a variety of ways.Computer Virus
Definition: A computer virus is a program or piece of code that is loaded into your computer and runs against your wishes, without your knowledge. With a particular insidious agenda in mind, all computer viruses are man-made. Viruses can also replicate themselves.
Aftereffect: Similar to the common flu virus or Covid19 virus, a computer virus is engineered to spread from host to host system and has the ability to replicate or mutate itself. Likewise, just as viruses are unable to replicate without a host, computer viruses, as is the case with a file or text, are unable to reproduce and spread without programming.Phishing
Definition: Phishing is the misleading practice of sending emails that pretend to be from reputable companies or individuals to tempt individuals to disclose personal information, such as account passwords or credit, account numbers, current or account accounts, or savings accounts.
Aftereffect: Phishing is a cybercrime in which, via email, telephone or text message, someone posing as a legitimate institution approaches a victim or target to attract people to provide confidential data such as personal information such as banking and credit card details and passwords.
Adware
Definition: Software that displays ads and is available at low cost or free of charge and is incorporated into another application. Adware is a form of spyware that collects data about an internet user's browsing habits and displays targeted or contextual advertising to entice users to participate in the hoax.
Aftereffect:The advertising functions within legitimate software are built into or bundled with the application. Typically, the developer sees Adware as a means of recovering growth and other costs and generating revenue. In certain situations, the developer can offer the software to the user free of charge or at a reduced price in the hope of obtaining an arrangement.
Trojans
Definition: A Trojan is software that displays or downloads advertising material such as banners or pop-ups automatically when a user is online.
Aftereffect:A Trojan horse or trojan is a form of malware that is often masked by cyber criminals and hackers as legitimate software that can be used in an effort to gain access to user systems. Users are usually tricked by some form of social engineering into loading and executing Trojans on their systems. Trojans allow cyber criminals, once enabled, to spy on you, steal your confidential information, and gain backdoor access to your system that can be exploited at a later point in time. Acts of this kind may include:
Internet Bots
Definition: A software program that uses the Internet to perform automated tasks is an Internet bot, a web computer, a robot or simply a bot. Usually, bots perform tasks that are simple and repetitive, far faster than a human could do. The most comprehensive and common use of bots is web crawling, where an automated script fetches, analyzes, and files web server information. Over half of all web traffic is produced by Bots.
Aftereffect:Internet robots are often called spiders, crawlers, and web bots. While they can be used, such as search engine indexing, to perform routine tasks, they also come in the form of malware. Malware bots are used to gain absolute control over a machine or network or other digital devices.
Computer Worms
Definition: A computer worm is a type of malicious software program whose primary purpose is to infect other computers while remaining active on infected systems until it is triggered. A computer worm is self-replicating malware with the intention of causing confusion, duplicating itself to spread to uninfected computers.
Worms are vicious computer virus that made its occurrence in 2000's. It sends out an email with a subject line – ‘230 dead as storm batters Europe’ targeting people interested in news. As soon as the user clicks on it the worm starts to create problems.
Aftereffect:strong> Worms usually cause damage to their host networks through bandwidth usage and overloading of devices and web servers. Computer worms may also contain 'payloads' that, once delivered, damage the host devices. Payloads are computer code pieces written by hackers to perform acts that go beyond just spreading the worm on the computers affected.
