Without further ado, let’s look at our top picks of the best antivirus programs.

1. Norton – Best Overall Antivirus Provider


  • 100% malware protection on Windows, macOS, and Android
  • Excellent parental controls
  • Full identity theft protection 
  • $1 million identity theft insurance option
  • Money-back guarantee


  • Mac users miss out on parental controls, cloud backup options, and more
  • Identity protection features only available to US citizens

Norton 360 is one of the best antivirus protection programs in the industry. The company is known for its state-of-the-art bonus features and cross-platform capabilities with its support of macOS, Android, and IOS.

The program offers protection against online and offline threats, and the Norton 360 deluxe paid version offers total security in the form of phishing protection.

Additionally, Norton adds a password manager, doesn’t spam customers with notifications, and has a platform that runs smoothly with minimum lag on windows, macOS, Android, and other devices. The top three features that Norton 360 offers are:

Outstanding Security Features

Should you choose Norton 360, you will receive a software system based on five core security features. These features include device security, secure VPN, a password manager, cloud backup, and parental control.

Cloud-Based Backup

Norton offers a cloud backup feature whereby you can remotely store all your important files. Their most inexpensive plan includes up to 10GB of cloud storage, while their most expensive plan will give you up to 75GB of cloud-based storage.

Password Manager

Possibly one of the most attractive extra features in Norton’s arsenal is their password manager. Customers can impressively auto change their password on various compatible sites. They can also store usernames and card details through secure 256 bit AES encryption.

What Consumers Say

Norton has numerous positive online reviews from customers and experts alike for security, ease of use, and support. The average overall satisfaction rating across the board was a competitive 9 out of 10.

2. McAfee – Best Allrounder with Affordable Pricing


  • Four pricing options available 
  • Excellent customer support
  • Industry competitive security features
  • Compatible with Android, Windows, Mac, and IOS 
  • Free version available


  • Interface not as user-friendly as other programs
  • Limited total protection features

McAfee total protection is affordable while still retaining essential safety features that protect against malware, spyware, and it is compatible with Android and IOS. This antivirus also offers a file shredder feature, which is a big positive for many people. These are the notable features McAfee comes with: 

Fast and Efficient Virus Scan Function

The McAfee antivirus software gives customers two different virus scan tools, either a quick scan or a full scan. The quick scan feature is ideal if you don’t have the time to do a full scan as it only takes 5 minutes as opposed to the full scan, which takes an hour.

Unique McAfee WebAdvisor

The unique McAfee WebAdvisor extension feature allows for a secure browser and adequate internet security. WebAdvisor will tell you if there are any malicious malware issues detected and alert you of suspicious activity.  

Simple Mobile App

The free antivirus app offers real-time protection through scanning functions that allow you to check if wi-fi connections are secure and analytical reports of your scans and data.

What Consumers Say

Amongst customers, McAfee is a provider they trust due to its free antivirus version. The free version offers many of the perks that the paid version supplies. 

However, customers have complained that the features are hard to use, and some get irritated with all the system pop-up notifications.

3. Panda – Best Free Antivirus


  • USB protection
  • Free VPN included
  • Improved password manager
  • Excellent malware detection tools
  • Doesn’t affect your device speed negatively


  • No internet security, malware, or phishing protection on IOS
  • VPN limited to 150mbs/day

Panda software is perfect for home and business users. This program is of middling quality as it isn’t as comprehensive as some of its industry competitors.

However, the program does offer parental controls, a full security suite, performance optimization tools, and a gaming mode. Moreover, the company offers an attractive 30-day money-back guarantee should you decide they are not the antivirus provider for you. Below are three of Panda Domes tools:

Panda Rescue Kit

This is a desirable Panda software component; if you have an infected PC with malware and viruses, you can save your computer and files using the Panda rescue kit. You would do this by creating a rescue USB drive and then use their cloud scanner tool to clean the PC.

File Encryption and Shredding

These tools allow you to delete files completely by shredding them, and you can create a file extracting archive that will allow those without the tool access to them.

Panda Mobile App

Panda supplies customers with a superb Android mobile app; however, the iPhone app leaves much to be desired. The app houses family tools like parental controls and child tracking. Additionally, it also has an antivirus scanner, call blocker, and anti-theft tools.

What Consumers Say

The Panda antivirus software is a contender on this list. However, it doesn’t hit the mark completely in the customer support and pricing arenas. Consumers enjoy the free VPN and the extras but have issues gaining support from the company when they have issues with the software.

4. BullGuard – Best In Performance


  • Ideal protection for safe browsing
  • Innovative and intuitive design
  • Doesn’t affect your PC’s speed
  • One of the highest scores on Trustpilot
  • 30-day money-back guarantee


  • Does not support iOS
  • Only basic protection for Mac users

 Although BullGuard doesn’t offer as many options as its competitors, the tools they do have on offer do very well. In 2021 BullGuard has seen many key improvements that make the software stand out in the industry. Below are a few of their key components that perform well:

Improved Vulnerability Scanner

The vulnerability scanner that BullGuard provides will identify suspicious practices, and it will alert you to unsecured wi-fi networks and certain drivers with no digital signature.

Premium Home Network Scanner

This premium feature will prevent all unauthorized devices from connecting to your network. They take it one step further by tracking all device network activity to warn you of any suspicious behavior.

Newly Introduced Firewall

A huge point of contention before 2021 was surrounding the fact that BullGuard did not offer a firewall. This is now a concern of the past as they have introduced a capable, fully functioning firewall for users.

What Consumers Say

Most consumers are happy with BullGuard as they are easy to use and also have decent customer service and pricing across all their plans. However, some users who use the software with children are not overly fond of the privacy filter tool.

5. Vipre – Best For Businesses


  • High accuracy rating at AV-Test
  • Top tier plan grants uncapped VPN
  • Caters to businesses
  • Consistent high ratings at independent testing labs
  • 30-day money-back guarantee


  • High pricing after initial sign-up discount
  • Limited firewall protection

The limited features make this antivirus program more suitable for businesses. The program works well for businesses because of its software patching capabilities, auto-installs, and management tools.

Vipre has relatively advanced security with its firewall and spam filters. However, these components don’t fully measure up to industry standards as many of the firewall features are disabled by default. Despite this, their dark web scanner, webcam, and microphone protection somewhat make up for what the program lacks. Noteworthy tools include:

Antivirus Functions

Although the antivirus functions are basic, they are straightforward to use. The dashboard is easily navigable, and the scan capabilities are functional.

Patch Control

The manage patches tool automatically detects any new updates for common applications and auto-installs them saving users time.

Spam Filter Capabilities

Vipre’s Advanced Security plan includes a basic spam filter that scans POP3 and SMTP traffic for any mail that presents junk status potential.

What Consumers Say

Some swear by this antivirus software for businesses, while others state that the program needs some big improvement. Many consumers have been drawn to the introductory discount price. If you’re looking for a low-priced antivirus for your small business, this one could be the best alternative for you.

6. Kaspersky – Easiest to Use


  • Offers Kaspersky cloud protection
  • Affordable 
  • Excellent malware and ransomware protection
  • Virtual keyboard for on-screen commands
  • Free protection tools available


  • Password manager store 15 passwords max
  • Poorly written and unorganized FAQs

Kaspersky antivirus offers many extras like malware identifying tools, an easy-to-use interface, and works well with most operating systems.

Despite the limited VPN capabilities and some hard to enable tools, this software is still prevalent amongst gamers and avid internet users. We have listed below a few of the noteworthy items the software comes with:

Kaspersky Mobile App

The Kaspersky mobile app has a wide array of free tools, such as many anti-theft tools that include locking your phone if your sim has been removed. There is a real-time on-demand malware scanning function if you’re worried a site has breached your phone.

Kaspersky Safe Money

The safe money tool can prohibit attackers from accessing your payment information. The virtual keyboard they use will prevent your payment information from being logged.

System Usability

For many years, customers have put their trust in Kaspersky due to its straightforward interface and ease of use. More and more people are attracted to Kaspersky’s fast installation times and scanners that don’t slow down computers or other devices.

What Consumers Say

Many customers are pleased with the easy-to-use system and well-developed privacy and security components, but many are unimpressed with the customer support. Some have complained that they have emailed and tried to make contact with no response or a late one from the support team at Kaspersky.

7. Avira – Good Free Antivirus


  • A free security suite
  • Reliable password manager
  • Exemplary anti-phishing and anti-malware protection
  • Ideal entry-level antivirus program


  • Many features require the paid version
  • Slow on-demand scanning feature

 Should you seek an antivirus compatible with a Windows operating system while having a large range of system optimization tools such as a file shredder, disk defragmenting, and file encryption, then Avira could be the best bet. Avira is not only user friendly but also provides a free version of their antivirus product.

The advanced Avira Prime paid plan option offers an excellent anti-malware engine that provides exemplary security against spyware, ransomware, and most viruses, with some users reporting a 100% effective rate. Some of the top tools by Avira virus protection include: 

Unlimited VPN

Unlike other antiviruses, Avira’s Prime version offers unlimited VPN browsing data capabilities and follows a strict no-logging policy ensuring your data isn’t sold to third parties.

Web-Based Password Manager

Avira’s password manager is wholly web-based, which is a huge positive for some customers. Additionally, Avira antivirus uses bank-grade encryption to ensure all your passwords are kept safe with their simple and efficient password dashboard.

What Consumers Say

Avira antivirus has proven to be an option that many consumers opt for when it comes to an antivirus plan for their PCs due to their free version. Many are more than happy with the wide array of capabilities that this program’s free version has.

8. TotalAV – Best In Security Protection


  • 7-day free trial
  • 30-day money-back guarantee
  • Defends against 99% of malware attacks
  • Four different virus scanning options
  • Impressive premium security features

Virus Scan Capabilities

TotalAV has an almost perfect 100% detection rate when it comes to malicious threats. This is well above the industry standard that falls in the 90% range.

What Consumers Say

Arguably the only downside that many users report is the high pricing on TotalAV’s plans. Consumers are frequently unimpressed with the so-called special limited-time deals that other providers offer for one fee in their premium plans.

9. Bitdefender – Best Entry Level


  • Excellent privacy features.
  • Great discounts available
  • Doesn’t slow your computer down
  • Scores high in performance tests

The BitDefender Antivirus Package Plus packs quite the punch when it comes to value for money, with their services being on par with much of their competition. This entry-level software is ideal for people who don’t have children and don’t require parent control tools. The software has many impressive tools, such as:

How To Choose the Best Antivirus Software?

Choosing the perfect antivirus software for a secure browser can be somewhat challenging.

Malware protection, parental controls, anti-phishing, a free trial, and unlimited VPN capabilities are not the only essential factors to consider when deciding.

Take Antivirus Testing Labs Seriously

Antivirus testing lab results will give you a good indication of how well an antivirus program truly runs and how it comes to the other ones on the market. Often the results from a lab are a good indication of an unbiased opinion on how well an antivirus performs across the spectrum of services and tools offered.

Ensure Total Protection

There are many plans from various providers that don’t offer everything you might need. Be sure to choose the right pricing plan when signing up, as the most expensive one usually offers the most tools and functions. Without adequate tools, your devices could fall victim to threats that you could prevent.

Look for Additional Features

Many providers will have a wide variety of additional features from which you can choose. Try to narrow down your wants and needs, and if you need a free version, monthly or per year subscription, and take it from there. Look for VPN services, password managers, parental controls, and if the provider offers a free version. 

Check for Regular Updates

Failing to check for regular updates can have catastrophic consequences to your data and computer. Without regular updates, the antivirus you have installed won’t run smoothly or properly.
