2021’s Best Antivirus Software

They should probably sell Antivirus software in a pharmacy because, in the long run, it will save you a lot of headaches. 

As computers have become an increasing part of our daily lives, we have become increasingly dependent on them. Not only do we need them, but we also need them to work fast and without glitches.

So, basically, you really do not want to catch a virus on your computer. It’s just problems and hassles you don’t need. Luckily, there are several companies on hand to help protect you from these dangers.

The following list breaks down the best antivirus software on the market right now. 

1. Bitdefender Antivirus Plus 2020


This stalwart of the antivirus world is a top-three contender on anyone’s list and for good reason. The software is both reliable and precise in its virus detecting which means your computer is safe in Bitdefender’s hands. 

Features include web filtering, which blocks access to any malicious websites, and a secure browser for keeping card details safe. There is a password manager, an anti-phishing module and an excellent multi-layer ransomware protector.

On the downside there are a couple of issues – it takes beaucoup resources, and can conflict with other programs (although rarely). On top of that, it covers a maximum of one device at a time and mac users and will need a Mac-specific version.

Available Upgrades

  • Bitdefender Internet Security 
  • Bitdefender Total Security 

2. Norton AntiVirus Plus


Norton claims to offer an advanced level of privacy and financial security through its connection to the global civilian intelligence network. One thing’s for sure, It’s certainly one of the best antivirus software on the market.

Capable of blocking brand new malware, it also makes an incredibly minimal impact on your system resources. In addition to this, a URL blocker keeps you off mal-affected sites, and the file reputation service stops suspicious downloads before they do any harm. 

There’s no getting around it, Norton is the top of its class. Its intelligent behavior monitoring is second to none and can be used to scan for viruses in a number of sophisticated ways. 2GB of cloud backup and a password manager are thrown in for good measure, making this an excellent overall package. 

Not everything is roses, there have been problems reported with browser extensions. For example, the Chrome version has been known to stop suddenly without explanation. This is no isolated exception either as there have been multiple reports of this phenomenon. However, it is rare enough that it doesn’t take away from an otherwise stellar product.

3. Kaspersky Anti-Virus


With this offering, Kaspersky has developed one of the best performing security packages currently available. It’s super user-friendly and full of features such as Automatic scans, drive-by crypto mining, and real-time infection prevention. On top of that, it can cover five devices at a time.

Kaspersky’s accuracy in detection helps it identify and remove threats, it does this by utilizing web filtering to block dangerous URLs, and smart monitoring technologies to undo any malicious protocols.

Its well-designed interface comes with some pertinent on-screen explanations as you navigate through the set-up. This is the perfect choice for a beginner.

4. Webroot SecureAnywhere AntiVirus

Webroot offers a 70-day money-back guarantee on this product because they are confident that users will be satisfied. For the most part, they should be. This is an extremely lightweight, fast, and efficient software.

The always-on security protection layer helps protect you against everything from identity fraud to phishing. The firewall, as with everything Webroot does, is lightning fast and low maintenance. Unsurprisingly, it doesn’t take long to set up and it barely touches your memory. 

Webroot hasn’t gone through as much pro-testing as the other brands on this list so there could be some issues lurking in the background. For now, we will have to wait and see.

5. F-Secure Antivirus SAFE

Welcome to SAFE, the latest and greatest from F-Secure. This excellent software is available on all the major operating systems and can cover three devices at once. In addition, it is user-friendly and lightweight on your computer’s memory.  

It offers browsing and banking protection, enables a family rules measure for site blocking and round the clock ransomware protection. All this combines to make a package of great value for the regular surfer looking to bolster up their security. 

There is a minor negative, this software is a little too eager to catch the bad guy. In tech terms, that means it is prone to false positives and what it amounts to is that it blocks sites that are actually unharmful. This isn’t something that should disrupt the average user, and there are ways around it, but it can be bothersome for some.

6. Trend Micro Antivirus + Security


Trend might not be the most feature-laden and efficient software on this list but it does have several things going for it. Firstly, it does a good job of keeping you safe from viruses. Secondly, it’s very affordable. 

Although Mac users will need a Mac-specific version, and it only covers one device, it is in many ways an antivirus for the people. Why? Well, it’s easy to use and offers strong protection against ransomware and email scamming threats. It also runs on advanced AI learning algorithms and has an above-average anti-spam protector. 

There is a little confusion as to whether this software is guilty of false positives or not, with good arguments for both sides. However, a 30-day free trial should be enough to help you decide whether Trend does have a hair-trigger or not. 

7. ESET NOD32 Antivirus

Just by looking at the name you can tell there is something intensely technical going on with this software. Don’t be mistaken, all the software on this list is hi-tech, but this takes it to another level.

Given all this, it should come as no surprise that this software is aimed at the experienced user. It can cover five devices at once, has an impenetrable ransomware shield, and provides an extra alert UEFI scanner. It also boasts real-time malware protection, and one of the best heuristic detections around.

As you might expect from a techie friendly software, it is highly configurable and extremely powerful. Surprisingly, a lot of the standard features you find with other packages are missing from this one. There’s no firewall, file shredder, password manager, or vulnerability scanner, but there is some of the best protection around.

By focusing on the fundamentals, ESET has delivered above-average protection.  

Available Upgrades

  • ESET Smart Security Premium
