With the increased use of computers and the internet across the globe, the threat of virus attacks on the systems has also increased. These attacks pose a risk to the data security of individuals as well as organizations, and data theft is a huge risk if a system does not have antivirus software.
When it comes to data security, antivirus software plays an important role in protecting confidential information. For individuals, antivirus is essential to secure financial transactions and privacy of any other data, and it is recommended for everyone to prevent threats from external drives, CDs, and browsing the web.
However, before investing in antivirus software, it is important to consider some factors to make an informed decision about which one suits your requirements the best.
A software program made to search for, detect, and prevent any virus threats to the computer is referred to as an antivirus. Without an antivirus, a computer is at the risk of a virus attack the moment it connects to the internet. These attacks are constant and thousands of new malware are created daily, so detection tools provided by antivirus companies need regular updates to keep up with and prevent the latest cyberthreats. With the advancement in technology, some new malware can avoid detection and cause permanent damage to the system, and privacy and data may be compromised. This is where antivirus software comes into the picture and prevents these attacks.
Once a computer is loaded with an effective antivirus, the software will start scanning the computer. All the programs will be scanned for certain known types of malware and any unwanted or suspicious behavior in the system that may indicate the presence of an undetected, new malware. Usually, an antivirus will use three scanning processes:
The cost of antivirus can vary based on the plan opted for. A basic antivirus used in home computers provides virus protection, firewall protection, and protection while browsing the web by showing a warning before entering malicious websites. This basic software cost less than the other premium software with advanced security features.
Antivirus that can boost the performance of a system are also available in the market. These packages are a little more expensive than the basic ones, but they also include anti-spyware and anti-virus software. These packages are designed to provide a diagnosis of any problem with the computer and even fix them.
Some more advanced antivirus software packages provide stricter security against malware that comes into the system through the web. These enhanced security features make these antivirus options expensive, but the additional levels of security are worth the price. This type of antivirus software provides antivirus security, firewall, anti-spam filters, firewall, chat, and file encryption, and file shredder.
Even the best antivirus can slow down the performance of a computer, and a computer can usually be slowed down by as much as 50%. Although advancement in technology has lead to the slowdown not being a big problem anymore, it cannot be ignored that having an antivirus on the system will hamper the overall performance of a computer.
When a computer has antivirus software, its programs keep scanning and working constantly, which puts the system to continual use. These scans can take place at regularly scheduled intervals, every time an app is downloaded, or every time a file is downloaded from the internet. These regular scans require power to function, and they affect the overall performance of the computer.
No protection makes a system a hundred percent safe from hacking, but having an antivirus loaded on the system can reduce the risk of everyday malware attacks, which can pose a serious threat to data security.
Antivirus software is typically built to prevent malware attacks on the system, and some software is also equipped with the feature to remove malware from an infected computer. However, a stand-alone malware remover is a more convenient option of detecting and removing viruses from the system, so ensure knowing the requirements is important before investing in an antivirus.
There are many modern antivirus software designed to offer a layer of protection against phishing attacks. Although these products do not prevent phishing emails from dropping into the inbox, they identify phishing websites and block the page, preventing them from loading.
Once ransomware has taken control over a computer, no antivirus can stop it, but there are many antivirus software that can prevent ransomware. Meanwhile, the existing antivirus software options are also being enhanced to enable them to overcome the threat of ransomware.
There are more than enough antivirus software available in the market, which makes picking the best one much more difficult. Listed here are some of the most popular antivirus software to choose from:
Norton Security is a product of Symantec and has been a pioneering leader in antivirus and malware protection business since 1989.
An intuitive, fair-priced antivirus system with advanced malware engine and a comprehensive suite of features to protect your device and data.
A popular and reliable antivirus solution designed for home users with useful features including identity theft protection and great customer support.
Although it cannot be foolproof security against malware, investing in antivirus can protect a computer from unknown attacks to a very large extent. Also, digital security is very important to prevent identity and data theft, so having an antivirus loaded on the system is beneficial.
