Your device can get attacked by a software which is capable of remaining undetected and cause a lot of damage to the system. Even if you have already installed you cannot consider yourself to be safe.
This is because cyber threats are also evolving with evolving technology. If a company is using the latest technology to tackle cyber crimes then the cybercriminals are also using the technology to commit cybercrimes. So it is very essential to always have updated antivirus software. Even if there is a small crack in the security system the cybercriminals will find a way to get in the system. The antivirus software acts as a shield for your computer. Not only that but the antivirus software also scans for malware and destroys if it finds any. Antivirus software is an integral part of the online and offline security of a computer to prevent any kind of data breaches and security breaches. Because this malicious software actually acts like a virus as they spread from one computer to another. These viruses infiltrate a computer then they start replicating and damage the operating system.
What the software does is it selects specific files to see if those files have any kind of malicious software in them. The software does not ask for any type of permissions it automatically schedules the scanning of files. But the software also scans a file or the entire system on your command. It then deletes the malicious programs and software then confirms the safety of your computer. Even people are getting more aware of this problem and started installing antivirus software consciously. They are doing this because they do not want to leave their computer vulnerable to any cyber threats. Now let’s look at some of the advantages of using antivirus software.
Antivirus software blocks spams and ads
The sheer number of viruses that are being transferred to a computer system through the pop up ads will leave you astonished. According to sources pop up ads are one of the major sources through which computer viruses are transferred. Not only pop ads but websites are also a major cause of transmission of these viruses. These ads and websites act as a gateway for the malware to infiltrate your computer and cause damage to your files. Antivirus software blocks all the pop-up ads and websites that contain malware in them which ensure there is no direct access to your computer.
Protects your computer from viruses in removable devices
Removable devices such as USBs are the most common devices that people use to transfer data to and from the computer. If you have been using a computer for a long time then you must have noticed that your computer slowing down and crashing after you have connected a USB that you borrowed from a friend. Have you ever thought about why this would happen? This because of your computer getting infected by a virus that was present in the USB you have borrowed from your friend. Here the removable device acted as the source of transmission for the virus. But one cannot stop using USBs as it is the most efficient way of exchanging data offline. What to do in order to prevent your computer from getting infected by malware through removable devices? All you have to do is install antivirus software that can scan removable devices. This software has the ability to scan and remove the viruses from the removable devices so that your computer does not get any.

There is also some antivirus software that can automatically detect and delete files that are unnecessary which boosts the speed of a computer and clears up disk space.
Protection from contraction and transmission of viruses
The main function performed by any antivirus is a prophylactic function. The purpose of this function is to scan for any potential viruses and remove them if detected. One should know that this is mostly done before the virus harms the system. This means that most of the malware is dealt with even before affecting the system. Most of the antivirus software blocks and tackles many malicious software many times in a single day. If a system contracts any virus it can potentially transfer the virus to other systems. A computer does this through a common network between other systems. So if any of your friend’s system gets infected by malware then there is a high chance for your system to contract the same malware. This is because you have a common link in the network through which you communicate with each other. You can easily stop this if you have anti-virus software. With the help of this antivirus software, you can not only protect your system but also protect the systems of your closed ones by blocking the transmission of the virus.
Protection from hackers
The most common technique used by any hacker to infiltrate your computer is by planting malware in your system. They do this without the victim having any knowledge of it. The hackers do this by sending emails that have malware in them. Once you open the files the malware gets transferred to your system giving the hacker full control over your system. This will give the hacker access to all the files and programs in s computer. The hackers have all the information about the victim. They can damage, delete, and steal the data for demanding ransom. Antivirus software performs regular scans to ensure that there are no signs of hacking software’s presence. Some of these antivirus software also has an anti-hacking lock that blocks malware in a computer network. So if you have antivirus software then you are safe from hackers. Moreover, most hackers only go for easy targets. Even if a system has little protection they do not target it as it is a waste of time and effort.
Enhances web protection by limiting access
One of the major sources for contracting a virus is the accessing of unauthorized websites. Unauthorized websites expose your computer to various kinds of cyber threats like hacking, ransomware, spyware, and many more. All of these threats put your entire files and data at risk. But if you install antivirus software then access to these types of websites gets limited. The antivirus software restricts all kinds of actions in an unauthorized network. It does so to make sure that your computer is safe from malware present on the website you want to access.
Firewalls are one of the common features that are used to prevent any unwanted software or program from entering a system. A firewall’s function is to monitor the incoming traffic and outgoing traffic of your computer. The firewall checks each and every file and data that is sent from the computer. It also checks all the files and data that is received by the computer through the internet. People often unintentionally open an email or a website that has malicious software in them. These emails and websites are often the cause of phishing attacks. A phishing attack specifically targets a person’s credit card information, logins, and other data related to the person. These types of attacks are mainly aimed to rob the victim’s money through online transactions. If you install an antivirus software then it blocks all those files and emails that try to harm your computer.
Each and everyone has accounts in social media, banks, e-commerce websites, and many more. All of them protect the information in these accounts through passwords.
