As it was mentioned before, Kaspersky offers products and tools across all the major operating systems, for users and businesses. When it comes to Windows home users, Kaspersky offers users four different packages that can cover up to 5 devices:

  • Kaspersky Anti-Virus
  • Kaspersky Internet Security
  • Kaspersky Total Security 
  • Kaspersky Cloud Security 

Kaspersky also provides a free 30-day trial version, to try one of the Kaspersky products.[3]

Kaspersky Antivirus

Malwarebytes provides users with a free version of the application that scans the system for malware, viruses and other similar cyber threats and PUPs, and cleans infected devices. Malwarebytes Free complements antivirus, while Malwarebytes Premium is able to replace antivirus.


Malwarebytes home users offer proven Malwarebytes antivirus technology for various devices:

  • Malwarebytes for Windows
  • Malwarebytes for Android
  • Malwarebytes for iOS
  • Malwarebytes for Chromebook

All Malwarebytes Antimalware products:

Products for Home users Price / Devices / 1-Year Get it
Malwarebytes for Mac $39.99 / 1-device / 1-year
Malwarebytes for Windows $39.99 / 1-device / 1-year

Once the software is downloaded and installed Malwarebytes provide users with a 14-day trial of the full version.[4]


As was mentioned before, Kaspersky offers Windows users various packages including Kaspersky Anti-Virus, Kaspersky Internet Security and Kaspersky Total Security.

  • Kaspersky Anti-Virus delivers essential virus protection for PCs and includes basic features, such as Security, Performance and Simplified security management.
  • Kaspersky Internet Security is developed to provide users with security that also protects privacy and can cover multiple devices. It includes all the Anti-Virus’ features and is compatible with PCs, Mac, and mobile includes privacy feature and protects users while they are shipping or banking online.
  • Kaspersky Total Security is a premium package by Kaspersky and also includes Parental Controls, Password Manager and File Protection.

When it comes to Malwarebytes, this anti-malware product is not a full-featured antivirus application, even though Malwarebytes Premium can replace antivirus software for Windows, Mac, Android and Chrome OS.

Malwarebytes Premium adds anti-malware and anti-ransomware features, protects from malicious and fraudulent websites, stops malware that decreases computer performance, cleans up infected computers, and protects Identity and Privacy from hackers.

So, that's probably it, when it comes to Malwarebytes features. It is an Anti-malware application that focuses on detecting and removing malware and other threats from your PC. 

Antivirus protection

Kaspersky uses popular antivirus technologies and combines a digital-signature matching engine with heuristic monitoring. Utilizing these two methods, the application is capable of detecting both, known and previously unseen malware threats.

All suspicious items are sent to cloud-based servers for further investigation.

Kaspersky has detected all the threats we have installed in our test PC running Windows 10, while Panda missed some malicious samples.

The independent AV-TEST[5] testing lab tested Kaspersky in its the most recent tests. Kaspersky demonstrated one of the best malware detection rates and detected 100% of both, zero-day malware attacks, including web and email threats and 100% of widespread and prevalent malware.

Malwarebytes is very powerful and demonstrated pretty good malware detection rates, as it detected more than 98% of malware on our test computer.

However, we cannot compare our test results to any independent testing labs’ results, such as AV-TEST because Malwarebytes was not tested by any of them. So we do not know how the application would be rated in bigger tests.

In this case, the winner is Kaspersky that demonstrates 100% detection rates.

System-performance impact and scans

According to our test results, Kaspersky Anti-Virus can slow down your system by a maximum of 10 percent, which is a perfect score.

In addition, AT-TEST also rated Kaspersky 5.5 out of 6.0, as it delivered better results than the industry average.

  • Slowing-down a system while launching popular websites – 36% (19%)
  • Impact on a system while downloading frequently-used applications – 0% (1%)
  • Impact on a system while launching standard software applications – 9% (8%)
  • Impact on a system during the installation of frequently-used applications – 13% (25%)
  • Impact while copying of files – 4% (3%)

Kaspersky ProtectionThe first scan took about 30 minutes, the subsequent scans were finished in less than ten minutes, which is pretty fast. In addition, its quick scan only took about 2 minutes to complete. During the full scan, the OpenOffice tool finished about 30% slower than the baseline, which is in the middle.

Malwarebytes Anti-malware has a relatively heavy impact on system-performances and can cause lags and interruptions. The application uses more system resources than most of the antivirus products. As we tested, Malwarebytes Anti-malware had an impact by 30% on our test computer which is more than the industry average.

Malwarebytes Anti-malware offers users quick and stable scans. The application offers users three types of scans, including the full system scan or the Threat Scan, Custom Scan and Hyper Scan.


Malwarebytes Anti-malware was not tested by any of the independent testing labs, it is unknown how the application would perform on bigger tests, this is why the winner is Kaspersky again.

User interface

Kaspersky has a modern design and the user interface is easy to use. However, despite this, there is an issue with navigation. If you move away from the Home screen, you will not have many choices – to use another feature, you will have to press ‘Return’ and only then you can choose another option.

At first sight, Malwarebytes can seem a bit complex, as it hosts of status details, multiple icons, assorted buttons, and five tabbed areas. However, once you use it, you will see that actually, the program is very simple and intuitive. The interface is easy to understand and navigate


According to OPSWAT’s streamlined Windows Anti-malware Market Share Report[6], which includes the most recent data collected for 6 months from June to December, Malwarebytes appears in the third place and takes 12.23% of market share, while Kaspersky is only in the seventh place with 6.65% of the market share.[6]

Antivirus popularity report

As you can see in the graph above, other popular products include AvastMcAfee Inc., BitdefenderESETWebrootSafer Networking Ltd with SpyBot Search & DestroyAvira, and Symantec with Norton.

The final verdict

Kaspersky is one of the best choices in the market. It offers flawless antivirus protection, 100% malware detection rates, and great features. However, its interface could seem a bit confusing and it does not offer a VPN service.

When it comes to Malwarebytes, This application will protect your computer not only from the usual malware, but from ransomware, infected sites, and various small threats. Malwarebytes is a great anti-malware software and worth its price after all if you need real and reliable protection against the latest threats on the Internet.

Final thoughts

As we tested both antivirus applications, we would say that Malwarebytes is a great choice for those who want to fulfill their security with an additional layer of an antivirus. In addition, it is great for those, who do not need that many additional features, instead focus on anti-malware protection.

For those who want to protect their entire household or family and are looking for full-featured security software, Kaspersky is a better choice.

The table below summarizes our test results. As you can see both programs have similar malware detection and removal rates, performance and usability results.
