Malwarebytes Premium
"Malwarebytes is the best tool available for removing existing malware infections and makes a strong second-layer addition alongside a primary antivirus. As a standalone primary antivirus, it's outperformed by Bitdefender and ESET in prevention tests."
Pros
- Best-in-class malware removal — removes infections that other tools miss
- Browser Guard extension blocks malicious sites, ads, and trackers in real time
- Free version available for on-demand scanning (no real-time protection)
- Low false positive rate — doesn't flag legitimate software
- Ransomware and exploit protection modules in Premium
- Clean, straightforward interface with minimal complexity
Cons
- Real-time protection weaker than Bitdefender or ESET in lab prevention tests
- Not ideal as a standalone antivirus on an uninfected machine vs. dedicated AV
- Premium price ($44.99/yr) is higher than ESET ($39.99/yr) for weaker prevention
- Mobile apps are basic compared to desktop versions
- No parental controls, VPN, or identity monitoring features
What Malwarebytes Does Better Than Traditional Antivirus
Remediation vs. Prevention
Traditional antivirus products are built primarily to prevent infections before they happen. Malwarebytes was built from the ground up to remove infections that have already occurred — a meaningfully different technical problem. An infection that has established persistence, modified system processes, and hidden from the OS file system requires different removal techniques than blocking an incoming threat at the network or file layer. Malwarebytes's scanning engine uses behavioral analysis, heuristic detection, and a proprietary threat intelligence database optimized for removing stubborn infections including rootkits, browser hijackers, adware, and ransomware remnants. Independent testing by organizations like MRG Effitas has consistently shown Malwarebytes removing infections that Bitdefender, ESET, and other prevention-focused tools leave behind after an infection has established.
Browser Guard Extension
Browser Guard is a free browser extension available for Chrome, Firefox, Edge, and Safari that blocks malicious websites, known phishing pages, advertising networks with a history of serving malware, and third-party tracking scripts. Unlike the VPN-based blocking in NordVPN's Threat Protection, Browser Guard operates as a traditional browser extension — it sees all traffic passing through the browser and can block at the individual URL level. In independent testing, Browser Guard blocked over 98% of known malicious URLs in test sets. It works independently of the Malwarebytes desktop application and is free regardless of whether you have a Premium subscription.
The Layered Defense Model
The most defensible use case for Malwarebytes Premium is running it alongside a primary antivirus product as a second layer of defense. Windows allows multiple real-time protection tools to run simultaneously (as long as Windows Defender is set to passive mode), and many security professionals run Malwarebytes alongside their primary AV specifically because its detection heuristics catch different threat patterns than signature-based prevention tools. If Bitdefender prevents 99% of threats and Malwarebytes catches a different 99% — overlapping heavily but not perfectly — the combination provides meaningfully broader coverage than either alone.
Where Malwarebytes Falls Short as a Standalone Antivirus
Prevention Lab Test Scores
AV-Test's Protection scores measure how many real-world malware samples and zero-day threats an antivirus blocks. Bitdefender and ESET consistently score 6.0/6.0 — maximum protection. Malwarebytes Premium scores in the 5.5-5.8 range, indicating it misses a higher percentage of novel threats than the top prevention-focused products. This doesn't mean Malwarebytes is weak — a score of 5.5 still means blocking 97-98% of threats — but for users choosing a single primary antivirus, Bitdefender or ESET offer better prevention rates at a similar or lower price.
Feature Depth
Norton 360, Bitdefender Total Security, and McAfee Total Protection all bundle features beyond antivirus: VPNs, password managers, parental controls, identity monitoring, cloud backup. Malwarebytes Premium is a focused product with real-time protection and malware removal — and that's it. Users who want an all-in-one security suite will find Malwarebytes insufficient as a standalone product.
Free vs. Premium Value
The free version of Malwarebytes is a genuinely useful tool — on-demand scanning for users who suspect an infection, or as a second-opinion scanner after their primary antivirus hasn't found anything. For users who only need occasional scanning, the free tier is sufficient. The $44.99/year Premium upgrade adds real-time protection, which is necessary for use as a primary antivirus but less compelling if you already run another real-time AV product.
Recommended Use Cases
Cleaning an Infected Machine
If you have a machine that behaves strangely — unexpected redirects, new toolbars, unfamiliar programs starting at boot, antivirus disabled without your action — Malwarebytes Free is the first tool to run. Download from malwarebytes.com (being careful about the many fake Malwarebytes download pages in search results), run a full scan, and let it quarantine everything it finds. After removal, run a second scan with a traditional antivirus like Bitdefender or ESET to confirm the system is clean. This two-tool workflow catches the broadest range of infections.
Pairing with Another Antivirus
Running Malwarebytes Premium alongside Bitdefender or ESET provides a genuinely layered defense. Configure your primary antivirus as the active real-time scanner, add Malwarebytes's real-time protection as a second layer targeting different threat categories (ransomware protection, exploit mitigation), and use Browser Guard in your browser. This combination provides broader coverage than either product alone.
Who Should Skip Premium
Users who have a modern primary antivirus (Bitdefender, ESET, Norton) installed, practice good security hygiene, and don't regularly download software from untrusted sources will gain little from Malwarebytes Premium as a second layer. Their existing protection is already strong. The free version is worth having available as an on-demand scanner in case something looks wrong, but the Premium upgrade is hard to justify for low-risk users who already run a good primary AV.
Who Should Buy It — And Who Should Skip It
- You have an infected machine that your current antivirus hasn't cleaned
- You want to add a second layer of protection alongside a primary AV
- You want Browser Guard for browser-level malicious site blocking (it's free)
- You need ransomware and exploit protection as a supplement
- You want a single primary antivirus with the best prevention rates (use Bitdefender)
- You want a full security suite with VPN and identity monitoring (use Norton 360)
- You're a low-risk user who already runs a strong primary AV
- You primarily use macOS — the Windows version is significantly more capable
Frequently Asked Questions
Can I run Malwarebytes alongside another antivirus?
Company Background & Trust
Notable Incidents & Disclosures
Threat actors behind the SolarWinds supply chain attack (suspected Russian state-sponsored group Cozy Bear) targeted Malwarebytes' internal systems via a dormant Office 365 email product. Limited access to internal email and some Azure infrastructure — no customer data compromised, no product code accessed. Malwarebytes disclosed this proactively.
Trusted. The 2021 incident affected internal Microsoft infrastructure only — no customer data or products were compromised, and disclosure was proactive. Clean record otherwise. Malwarebytes is most valuable as a free supplemental scanner alongside a primary antivirus.
Yes. Windows supports running multiple security tools simultaneously. Configure your primary antivirus as the active real-time scanner and enable Malwarebytes as a second layer. The two tools use different detection methods and complement each other well.
Is the free version of Malwarebytes useful?
Yes — the free version allows on-demand scans (manual scanning when you suspect a problem) and is one of the best tools for investigating a potentially infected machine. It does not provide real-time protection in the background.
Does Malwarebytes remove ransomware?
Malwarebytes Premium includes behavioral ransomware blocking that can detect ransomware activity (mass file encryption) and stop it. For removing ransomware that has already encrypted files, Malwarebytes can remove the ransomware process but cannot decrypt files locked by sophisticated modern ransomware — those require either a known decryption key or restored backups.
