Kaspersky vs Avast what is better? Don’t know? With this article, you will choose the antivirus. Viruses. Malware. Internet Security. Privacy Protection. All of these are buzz-words used by Internet Security companies to sell antivirus software.

In this article, we’ll cover the critical aspects of two industry favourites and, hopefully, help you decide who wins in the battle of Kaspersky vs Avast.

To compare these two products, we’ve compiled information on four different categories: Features, Malware Protection, System Performance, and User-Friendliness.

Kaspersky vs Avast: Features

While both Internet Security companies offer a wide range of services, Kaspersky edges out a win in this category.

Kaspersky antivirus


Like many of its competitors, Kaspersky offers a free version of its program called Kaspersky Free. It provides malware protection, but it does not offer advanced security-related features and utilities. The other downside of Kaspersky Free is that it is only compatible with Windows.

Kaspersky Antivirus is the next step up from Kaspersky Free and is the least expensive

Offering from the company. It offers the following features:

  • Protection from digital threats.
  • Vulnerability Scanner- a tool that checks for patches and loopholes in your system.
  • Silent Mode- a tool that silences all background programs while watching movies or playing games.
  • Advanced, multi-layered Ransomeware Protection.
  • Only for Windows PCs

The next level of protection is Kaspersky Internet Security

Features included:

  • Two-way firewall
  • Email Filter- keeps your inbox clear of junk/spam.
  • Protects against Webcam Spying
  • Hardened Browser- secures financial records during online banking or shopping.
  • Limited-use VPN
  • Windows PC, Mac, and Smartphone compatible

For an even higher level of security, they offer Kaspersky Total Security

Features included:

  • Password Manager- stores and manages all your passwords
  • File Encryption Utility- secures essential data
  • File Shredder- fully erases sensitive files in a way that makes them non-recoverable.
  • Parental Controls

Lastly, the top-tier from Kaspersky called Kaspersky Security Cloud, which includes the following features:

  • Personal and Family packages
  • Adapts to the personal settings of each individual user to give them the best experience.

AVAST antivirus


Again, just like Kaspersky, Avast offers a free version of its product called Avast Free Antivirus (incredibly unique product name). It costs nothing to download and install but lacks any of the features and functions necessary to protect against more sophisticated malware. One big positive for Avast is that it comes compatible with PC and Mac, free or paid versions.

Avast’s first, for-profit, upgrade is called Avast Internet Security

Features included in the upgrade:

  • Two-way Firewall
  • Email Filter
  • Sandbox Mode- allows you to open any suspicious files or apps safely.
  • Real Site- prevents fake DNS routing.

The next upgrade in services is Avast Premier which includes the following features:

  • Anti-spying Tool- prevents webcam hijacking
  • Shred Tool
  • Software Updates

Avast Ultimate is the highest level of protection offered by the company, and it includes:

  • VPN
  • Avast Clean-Up- helps improve computer performance by removing junk files.

Both of these companies offer an impressive list of features. Still, in the battle of Avast vs Kaspersky, Kaspersky takes the lead. Kaspersky takes this lead because of its larger variety of packages available and simply offering more services. However, Avast Free is compatible with Macs, so it may be a more attractive product for Mac users.

Kaspersky vs Avast: Malware Protection

Preventing malware attacks is the primary function and the hallmark of any antivirus software worth it’s salt.

According to data collected in unbiased tests conducted by AV-Test and AV-Comparatives, Kaspersky consistently outperforms Avast in the category of Malware Protection.

Results of the June 2021 AV-Test, Protection Test, show Kaspersky scoring a six out of six in the categories of real-time detection of web and email threats and detecting widespread malware discovered over time. Kaspersky outperformed Avast by only a narrow margin, who scored a five-point-five out of six.

AV-Comparatives June 2021 Real-World Protection Test, also had Kaspersky beating Avast. Kaspersky was given the highest possible ADVANCED+ rating. Avast was rated as second-tier level with a two-star ADVANCED rating.

In both tests, Kaspersky appears as the clear winner.

Kaspersky vs Avast: System Performance

Kaspersky Vs Avast

In the battle between these two antivirus products, we have to consider System Performance.

Based on the ratings from AV-Test and AV-Comparatives, both companies received scores of six out of six on their system performance tests. Both companies also received the highest possible ADVANCED+ ratings.

For the category of System Performance, Kaspersky and Avast are neck-and-neck.

Kaspersky vs Avast: User-Friendliness

In this category, it’s a no-brainer. Avast is the clear winner.

All it takes is one look at the interface for each company to see the difference.

Kaspersky’s interface is easy-to-use and straightforward; however, it leaves much to be desired. Its one-panel design makes the Kaspersky an at-a-glance interface that shows you the user very simply whether their system is secure or not. A big green checkmark at the top of the panel indicates clearly whether everything is okay. If there’s an issue, that checkmark will turn into a red X.

While Kaspersky’s interface does have options for customizing your interface, those options are limited.

On the other hand, Avast offers a sleek, modern interface that instantly pops out to the user from the moment they turn it on. The Avast interface is more visually appealing, but it’s also super intuitive. It offers a side rail with icons for all operations which open into the large viewing window. That said, Avast’s free version, which is not even close to the nearest paid-upgrade, comes with a host of annoying pop-up ads.

Overall, both companies offer simple platforms that make navigation a sinch. But, when it comes to interface design and the whole visual package, Avast puts out a prettier product.

The Wrap-Up

As previously stated, both Kaspersky and Avast offer great products.

Avast offers broader compatibility across all levels of its platform and a much more visually appealing interface. According to a study of customer satisfaction conducted by the Better Business Bureau, Avast has an A+ rating. Customer reviews across multiple websites show that customers seem to have more positive remarks for Avast than Kaspersky.

With all that said, Kaspersky may not have all the bells and whistles offered by Avast’s interface, but it provides far better functionality and malware protection. After a careful review of the utilities offered by both companies across all levels of their platforms, Kaspersky is objectively the superior product.
