Malwarebytes Review 2021

Advertiser Disclosure

Malwarebytes has launched its latest product, Malwarebytes 4. This new version is the first whole-number update in four years and comes with some great features. The product’s claim to fame is being smarter than its competitors due to anomaly detection, behavior matching, and application hardening.

So, is this the best product to keep you safe from malware? Here’s what you need to know.

This Malwarebytes review found that while the product boasts new features, its ability to detect and eliminate malware, especially new threats, is what makes it stand out.

If you are looking for extra security, this might not be the product for you. There’s no firewall, no specialist banking protection, no password manager, and no backup or parental controls — just the basics: malware detection and blocking access to malicious code and links. It’s important that you don’t confuse this product for an antivirus solution; you should rather think of it as an added layer of security that works in tandem with your antivirus software.

Malwarebytes Free Review

If you’re not sure whether this is the product for you, Malwarebytes Free lets you try the system out without committing financially. This version does not block URLs or offer real-time threat detection, but it will provide on-demand scans for malware, spyware, and rootkits. Malwarebytes Free is useful as a second-option scanner. For a completely free solution, you could run Windows Defender as your primary antivirus and then carry out a daily Malwarebytes scan. While it’s not perfect, this will protect you from most threats without breaking the bank.

Malwarebytes Premium Review

On the other hand, Malwarebytes Premium adds real-time protection, URL blocking against malicious websites, and an extra layer of ransomware protection. It installs quickly and doesn’t take up too much space on your computer — the package comes in at around 400MB of files.  

The premium version even offers a free 14-day trial for customers who want to try before they buy. Downloading the free trial is a painless process and all you need is an email address to get started. Malwarebytes Premium allows you to stay on top of your device and can stop malware in real time before it causes any damage to your operating system.

When put to the test, the software was able to protect itself from attacks in most cases and perform well. Although performing impressively during tests, there are multiple reports of AV-TEST results being inconsistent. To put this into perspective, Malwarebytes Premium placed last out of 13 other software solutions in SE Labs’ most recent report. The top six products, including Kaspersky and McAfee, blocked 100% of threats while Malwarebytes only blocked 76%, making it vulnerable to a quarter of attacks.

Regardless, many businesses who report losing user productivity due to malware attacks have credited Malwarebytes to have solved this problem and increased their bottom line.
