These two products solve different problems, which is why a head-to-head comparison confuses so many people. Here is where each one wins.
What Kaspersky does better
Kaspersky is a complete suite: detection among the best in independent tests, ransomware protection, protected payments, parental controls, VPN and password manager included in the Premium plan.
It is built to prevent: it blocks the threat before it gets in, and covers more devices and more people on a single licence.
What Malwarebytes does better
Malwarebytes was born as a removal tool, and that is where it stays unbeaten: already infected computer, hijacked browser, pop-ups appearing on their own, a system gone painfully slow. In those cases it fixes things in minutes.
It is also much lighter, and on Mac it is one of the most recommended choices.
Point by point
- Everyday prevention: Kaspersky wins
- Cleaning an already compromised system: Malwarebytes wins
- Parental controls: Kaspersky only
- System impact: Malwarebytes wins
- Included features: Kaspersky wins
- Price: Malwarebytes costs less
Can you run both?
Yes, and it is one of the few advisable combinations: Malwarebytes is designed to coexist with other antivirus products, which almost no suite allows. Many people keep Kaspersky as continuous protection and Malwarebytes as a second opinion when something feels off.
Features compared in detail
Kaspersky Premium includes real-time antivirus, ransomware defence with file restore, protected online payments, a firewall, VPN, password manager, parental controls, data breach monitoring and a check for outdated apps on the PC.
Malwarebytes Premium includes real-time protection against malware and ransomware, web protection against scam and malicious sites, removal of adware and unwanted programs, and a browser extension that blocks malicious ads and tracking. Bundles are available that add a VPN and privacy tools.
The difference is clear: Kaspersky is a complete toolbox, Malwarebytes is a specialised tool that does a few things very well.
Performance: which one slows you down less
Both have a modest impact on the system. Malwarebytes is lighter because it does less in the background, so it is preferable on older computers or machines with little memory. Kaspersky, in independent performance tests, still scores very well for such a complete suite.
On Mac, Android and iPhone
- Mac: Malwarebytes is one of the most appreciated names on macOS, especially against adware and unwanted extensions. Kaspersky also offers complete protection on Mac.
- Android: both have good apps, with app scanning and protection from scam links.
- iPhone: on iOS classic antivirus software has little room to act; web protection, VPN and password manager matter most, and Kaspersky offers more there.
The typical case: an already infected computer
If the computer is already compromised, the recommended sequence is: disconnect external devices, run a full scan with Malwarebytes, remove everything it finds, restart and scan again. Then change your important passwords from a safe device. Only afterwards install continuous protection, which can be Malwarebytes Premium itself or a suite such as Kaspersky.
The real price
Malwarebytes generally costs less, but it also covers fewer features. Kaspersky Premium costs more, but includes a VPN and a password manager you would otherwise pay for separately. For an honest comparison, add up what you would need to buy separately and always look at the renewal price, not just the first year.
How to decide
If your computer works fine and you want it to stay that way, with several devices at home to cover, take Kaspersky. If the problem is happening right now and the machine is slow or odd, start with Malwarebytes.
