What is an Antivirus Software?

An antivirus is a software program designed to detect and remove malware from a computer or mobile device. Traditional antiviruses scan your files against a built-in malware database, flagging unsafe files that match the database. More advanced antivirus programs use machine learning, heuristic analysis, and cloud-based malware directories to detect and remove zero-day threats and very sophisticated malware. All of the best antiviruses offer real-time protection, so they scan every file before it executes to ensure malware never even starts running on your device.

Why do you need an Antivirus?

In recent years, people have become increasingly reliant on electronic devices. It is crucial now, more than ever, to have adequate security to protect your personal information from viruses and hackers. That’s where antivirus software comes in. Antivirus software, also known as anti-malware, is a computer program used to prevent, detect, and remove malicious software from your computers, tablets, and mobile devices.

There are many different types of malware, viruses being the most well-known. Here we have highlighted some of the lesser-known types of malware that all security-conscious users should be familiar with. To learn more, follow our blog for the latest updates and information.

An Introduction to Antivirus Software

The recent news of hacking in the US serves as a reminder of what happens when we don’t secure our information. With digital predators wreaking havoc across the globe, it is all too easy for a teenager halfway around the world to gain access to your bank account, credit card number, and even your identity. As hackers develop increasingly sophisticated means of capturing your personal information, it becomes critical to protect yourself.

Your best defense against hacking is high-quality antivirus software. Today, around 2.1 billion people use the internet worldwide. This growth in online activity has led to an increase in the number of active hacker syndicates who make a living by stealing and selling your personal information. Despite claims that antivirus software is dead, it has never been more relevant. In fact, according to Marketwatch, the antivirus industry is expected to grow by over 11 percent over the next four years with over 5.4 billion users by 2021. People are demanding more security in an insecure age, which is why we have compiled this comprehensive review of the best antivirus providers available.

The Growth of the Antivirus Software Industry

But with so many different types of antivirus software appearing on the market, choosing the right one can be overwhelming. An enormous amount of trust needs to be placed on your software, as you’re relying on it to keep your personal information and your money safe. That’s why we’ve compiled a list of the best examples of antivirus software on the market today. For each brand, we’ve developed a review page that judges each type of software by different factors, including special features, pricing, and a detailed summary. This way, you can make an informed choice about which type of antivirus software works best for your particular needs.

Why You Still Need Antivirus Software

While most devices now come with antivirus software, it doesn’t guarantee that they are strong enough to withstand a hacking attempt. Just like stock speakers in a new car, the built-in version is usually of lower quality compared to the premium version. Programs like Windows Defender will find malware and viruses on your computer, but they won’t be able to remove them. Good antivirus software will not only be able to remove malware, but also protect your files against ransomware which is used by hackers to lock you out of your computer until you transfer the ransom money. The antivirus software reviewed on this site includes additional perks like spam filtering, password management, and phishing scam detection.

Tips for Finding the Right Antivirus Software

To determine which product best fits your needs, you will first need to specify which of your electronic devices you use to access personal information. Are you a casual user who keeps a limited amount of information on your device or do you use you regularly store large amounts of private information on your device? If you run a business, you will most likely need a more comprehensive program than an average person. However, keep in mind that even the average casual user accesses sensitive information such as credit card numbers and online banking passwords on their mobile phones, tablets, and personal computers.

You will also need to take into account the system requirements for each type of antivirus software. Do you use a Mac or PC? Computer, tablet, or phone? Each of these devices runs on different operating systems and you will need to know if your system can accommodate the software. Our comprehensive guide will provide you with the operating system requirements for each type of software.

If you’re smart, you will want to do some serious research before you choose an antivirus provider. The best places on the web (besides our review!) can be found on cybersecurity forums. The users on these sites really know their stuff and will provide you with testing reviews and other information that will lead you to the right pick. Some examples of good antivirus software forums include Windows Secrets and Wilders Security. Quora is another excellent resource for finding regular users’ opinions on the best antivirus software on the market. You can also try free trials of software you are considering, or rely on an expert who’s already tested the software. Some reliable sites which can perform a test include AV-Test.org and AV-comparitives.org.

If going through all the antivirus software options sounds like too much of a hassle, you’re in luck! Simply check out our reviews to get a sense of what each type of antivirus software provides, including operating system requirements, features and price. While we always advise you to conduct your own thorough research, we can still provide you with a basic comparison so you can narrow down the types of antivirus software that will best fit your needs and keep you safe from hackers.
