Antivirus software is an essential investment in today’s digital world. Around 32% of people use antivirus technology for business and personal use, while 41% use it for personal protection alone. As people continue to spend more time online since the 2020 pandemic, and the number of reported cybersecurity issues continue to skyrocket, Antivirus tools are more important than ever.

The question is, which antivirus software is best? There’s plenty of options to choose from. You can choose between all-in-one security suites with malware protection and VPN support, as well as simple, budget-friendly anti-virus tools.

Today, we’re going to explore some of the top antivirus software options to help you protect your digital presence.

What is Antivirus Software?

Antivirus software is a program or technology suite designed to protect against computer viruses. Today’s technology can set defenses to reduce your chances of being hit by viruses, search for evidence of virus issues, and remove malicious content from your PC.

The exact features of your chosen antivirus software will depend on the product you choose. Most will scan specific files and directories on-demand, and automatically for attack symptoms. You should also be able to schedule scans according to your needs, collect information on discovered viruses, and remove malicious code whenever its discovered.

Some virus software will also show you the “health” of your computer, by tracking things like how many protections you have in place.

Let’s check out some of the top Antivirus options.

Ideal for customers who want to invest in a more comprehensive form of protection, McAfee Total protection offers a lot of features with a lightweight system fingerprint. In other words, you won’t lose a lot of space on your device. There’s also the option to get multi-device coverage if you’re looking for safety for the whole family.

What Makes a Great Antivirus Software?

The best antivirus software will be the one that gives you absolute peace of mind when you or your family is browsing online or using a digital device. Today’s antivirus tools come with a host of fantastic features to make your life easier and safer. Here are just some of the things you’ll need to consider to ensure you’re getting a great product.

  • Quality antivirus engine: The most important feature of any antivirus software is a good antivirus engine. A highly rated engine will be able to scan your PC quickly and effectively, finding potential threats, without wasting your time on false positives. You can usually find basic insights into the accuracy and performance levels of antivirus software online.
  • Budget: You do get what you pay for when it comes to antivirus protection. While free services do exist, it’s often much safer to choose a premium package with more extensive coverage. Make sure you think about your budget carefully and consider trying a free demo or free trial versions of the products you like before you spend your cash.
  • Protection level: If you just need a core antivirus solution and some basic protection against malware, then you can buy a pretty simple antivirus solution without spending a lot of money. If you need more in-depth features like access to a VPN and extensive configuration options, then you may need to spend a little more.
  • Number of licenses: Most antivirus software providers will allow you to choose between buying one license to cover a single computer or device, or multiple licenses. Typically, you’ll be able to get a slight discount if you’re buying multiple instances of the software at the same time.
  • Extra security: It’s rare for most of the top antivirus products on the market today to come with antivirus protection and nothing else. There’s a good chance you’ll also be able to find things like malware protection, phishing protection, safer shopping and financial features, and even parental controls on your antivirus system.
  • VPN access: Although not all antivirus software options come with VPN technology built-in, it’s becoming an increasingly common feature. If you want complete privacy when you’re shopping or browsing online, a VPN can be a nice extra feature to have. It means you don’t have to go shopping for a VPN separately.
  • Ease of use: If you’re extremely digitally savvy and know your way around technology like antivirus software already, you probably don’t need to worry too much about ease-of-us. For everyone else, a clean, simple and easy-to-use interface will come in handy. Check out customer reviews to see if your software choice is easy to use.
  • Device optimization: A lot of modern antivirus tools come with device optimization features to ensure your computer or smartphone is working at its best. These tools allow you to clear out old files and get rid of malware whenever possible.

Don’t forget to check out some of the special benefits you can get from certain antivirus tools too. Products sometimes come with things like vault file protection for your secure files, or free cloud storage. These factors will definitely make a difference when you’re choosing the right item.
