Our job is to protect people from online threats, and independent testing is one of the best ways to measure how well we’re doing.
Malwarebytes nabbed AV-TEST’s Top Product award after scoring 17.5 points out of a possible 18 in the research organization’s most recent Windows security test. The award is the latest in a string of endorsements from third-party testers whose ongoing evaluations help keep us sharp.
Here’s a closer look at the results.
AV-TEST Windows Consumer Security Product Test
AV-TEST’s Windows Consumer Security Product Test, which took place in March and April, assessed 14 security applications across three categories: how well they protected Windows PCs from malware, how much they slowed down a device, and how often they raised false alarms.
AV-TEST noted in its synopsis:
“We focused on realistic test scenarios and challenged the products against real-world threats. Products had to demonstrate their capabilities using all components and protection layers.”
To receive the Top Product award, companies had to score 17.5 points or higher out of a total of 18, earning a maximum of six points in each category. Malwarebytes has received a Top Product endorsement from AV-TEST more than a dozen times since it first began taking the test in 2018.
MRG Effitas Consumer Assessment Certification
Malwarebytes once again came out on top in the MRG Effitas Consumer Assessment Certification, which tested eight security products to measure their ability to block malware, protect against phishing, and avoid false positives.
Malwarebytes was the only company to achieve Level 1 Certification, meaning we succeeded in stopping all 300 in-the-wild infections without causing damage to the device or its data, generated zero false positives, and blocked at least 79% of phishing attempts. Our phishing detection rate was 100%.
This certification is particularly impressive because the test used newly discovered malware samples, meaning most security products had not encountered them before.
AVLab Advanced In-the-Wild Malware Test
Continuing our winning streak, Malwarebytes received a perfect score (421/421) in AVLab’s Advanced In-The-Wild Malware Test, earning an “Excellent” certificate. The test applied existing threats currently circulating online, delivered the way a real user would come across them.
To receive the “Excellent” certification, a security product had to stop at least 99.6% of malware threats, either before they could run or during an attack. We detected and blocked every single real-world threat in an average of 0.508 seconds—a full 3 seconds faster than the industry average.
These types of independent assessments are important. They keep us on top of our game, which in turn keeps our customers safe.

Have you ever gotten a phone call and had a gut feeling that those random digits looked extra suspicious? It happens to millions of people every day. While many people have trained themselves to ignore such calls, they still pose a threat across the US. In fact, scammers stole more than $21 billion from Americans last year, according to the latest IC3 report.
That’s why we created Scam Number Check.
Now, instead of risking a call with a scammer, you can look up a number and get a clear answer in seconds.
How to use Scam Number Check
We know scam calls happen every day, and they can cost victims a lot of money. So we designed Scam Number Check to be really simple to use. It’s free, private, and instant.
If the number looks suspicious, you can choose whether to block or report it. Remember, reporting suspicious numbers helps protect others.
Understanding the results
Scam Number Check can provide one of three verdicts when you check a phone number. Here’s what each means and how you should proceed:
Do not trust this number. Multiple people have flagged this number as a scam. Don’t call back, don’t share personal info, and don’t send money if they ask.
This number seems safe. Based on available data, this number has not been associated with suspicious activity. It is our recommendation that you proceed with caution in this case.
We don’t have enough info. No information is available in the threat intelligence database. This doesn’t mean it’s safe, so proceed with caution.
Why it matters
Scammers like to pile on the pressure and create fake urgency so you don’t have time to think. If you don’t recognize a number, let it go to voicemail first. Then check the number with Scam Number Check to see if it’s been linked to scams or suspicious activity. This simple extra step might help you avoid sharing personal information, sending money, or falling for impersonation scams.
Scams are getting harder to spot every day. By making Malwarebytes even better at catching threats, we’re helping you stay one step ahead of scammers and cybercriminals.

You’re working hard late at night, replying to emails and planning the week ahead. Then suddenly, a PDF file requests access to your camera. Why would a PDF need camera access?
Cybercriminals often disguise spyware inside seemingly harmless files and programs. An unexpected request for access to your webcam can be a red flag that something is amiss.
Malwarebytes Windows Webcam Monitoring alerts you if a program tries to access your camera, so you can allow trusted programs to continue or block suspicious ones instantly.
Spyware doesn’t just steal passwords. Some malicious apps try to access webcams to secretly spy on victims or capture sensitive information.
What does Windows Webcam Monitoring do?
Sends you an instant alert when a program tries to access your webcam.
Allows only the programs you trust to access your camera, blocking everything else.
Lets you manage notification preferences in Privacy Controls. A dedicated “Webcam Monitoring” table shows recognized programs and gives you control over which apps trigger alerts, and which don’t.
With the benefit of real-time alerts, Windows Webcam Monitoring gives you visibility into which programs are trying to access your devices. And when it’s something you don’t recognize, it may even help you stop spyware before it can spy on you.
At Malwarebytes, we believe security shouldn’t be complicated. Windows Webcam Monitoring is another step toward giving you simple, proactive protection that works automatically, so you can stay focused on pretty much anything else.
Ready to take control?
Update Malwarebytes for Windows, go to Privacy Controls and enable Webcam Monitoring.
Some Malwarebytes users have recently noticed frequent web protection alerts while reading email in Yahoo Mail’s web interface. These alerts are caused by background connections from the Yahoo Mail page to a set of third‑party domains that our products and other security tools currently classify as risky.
What we are seeing under the hood
When you open Yahoo Mail in a browser, the page loads various embedded components for navigation, features, and metrics. As part of this, the interface makes calls to domains such as cook.howduhtable.com and related subdomains, sometimes in the context of URLs that include /ybar/mail.yahoo.com/ and a long encoded parameter. That encoded string often resolves to a URL like:
This suggests the traffic is being routed through what appears to be a sandboxed web component that Yahoo can use for things like telemetry, testing infrastructure, or mail features. It may also be part of an advertising or tracking flow, but at this time we cannot say with certainty exactly what purpose Yahoo is using it for.
Regardless of intent, multiple security systems have observed these redirect domains and assigned them poor reputations. Characteristics include:
Frequently changing, opaque subdomains that do not resemble normal consumer‑facing Yahoo addresses
Use of encoded parameters and chained redirects that make it difficult for users, and sometimes defenders, to see the final destination at a glance
Existing detections and blocklists from other vendors that classify the infrastructure as suspicious or potentially malicious
Because of these signals, Malwarebytes Web Protection and Browser Guard have been blocking a growing list of related subdomains to protect users, which is why some people see repeated alerts while using Yahoo Mail.
What we are not saying
It is important to be clear about what we do and do not know.
We have not established that Yahoo Mail itself is compromised or that Yahoo is deliberately distributing malware through its mail platform. What we can say is that third‑party or internal components invoked from within the Yahoo Mail web interface are making connections through domains that behave very similarly to infrastructure commonly associated with malicious or deceptive advertising and tracking.
From a security standpoint, this creates unnecessary risk. Any mechanism that injects content or runs sandboxed components via opaque redirect chains could, if misused or subverted in the future, expose users to harmful content without them ever clicking a suspicious link.
Blocking these domains is a precautionary step in line with our normal protection standards.
Why Malwarebytes blocks these redirects
Our decision to block these connections is based on a combination of technical behavior and third‑party reputation data:
The redirects are triggered by embedded components in the Yahoo Mail interface, not by users intentionally browsing to those domains
The infrastructure relies on frequently changing, non‑descriptive domains and subdomains, a pattern we often see in malicious or evasive advertising and tracking systems
Multiple security vendors and automated reputation feeds already flag these domains as risky or malicious, and some have seen them associated with unwanted or harmful activity
Because of this, Malwarebytes products currently block connections to these third‑party domains when they are invoked as part of Yahoo Mail’s web experience. This does not mean that all of Yahoo Mail is considered malicious. It means we are specifically interrupting a narrow set of background calls that present elevated risk.
What this means for users
If you use Yahoo Mail in a browser with Malwarebytes enabled, you may see:
Web protection or MWAC alerts referencing domains like cook.howduhtable.com or similar names while you are reading or composing email
Multiple alerts in a short period, because the mail interface may retry or rotate through different subdomains or IP addresses in the same family
In most cases, your email content itself still loads, though certain embedded elements, metrics, or ad‑related content may fail to load or behave differently.
How to stay safe and reduce interruptions
You should not need to lower your protection to continue using Yahoo Mail. Here are some practical steps you can take:
Keep Malwarebytes protection enabled Leaving Web Protection and Browser Guard on ensures blocks remain in place if these redirects change behavior or begin serving harmful content in the future.
Avoid allowlisting the suspicious domains While it’s technically possible to add exclusions for individual domains, doing so would allow their traffic to load unfiltered in your browser. We don’t recommend this unless you fully understand and accept the risk.
Use private/incognito windows for Yahoo Mail Accessing Yahoo Mail in a private/incognito session can help reduce persistence of certain tracking and advertising data because the browser discards cookies and local storage when you close the window.
Clear cookies and site data periodically If you see repeated alerts, clearing Yahoo‑related cookies and cached data may reduce some of the underlying tracking behavior that triggers these redirects.
Consider fewer‑ads options Yahoo offers paid plans that reduce or remove ads, and users can also use reputable content‑blocking extensions alongside Malwarebytes to cut down on ad‑driven behavior in webmail interfaces.
Our ongoing monitoring
The domains and infrastructure involved in these redirects are operated outside Malwarebytes, and their configuration or behavior may change over time. We are actively monitoring telemetry, sandbox reports, and reputation data for these domains and related infrastructure, and we will adjust our detections if new information emerges.
Our priority is to keep users safe while being transparent about why protection events occur, especially in widely used services such as webmail. If we learn more about the exact role of this component within Yahoo Mail, or if Yahoo provides additional clarity, we will update this article accordingly.
Stop threats before they can do any harm.
Malwarebytes Browser Guard blocks phishing pages and malicious sites automatically. Free, one click to install. Add it to your browser →
Have you ever been on a website when a pop-up suddenly asked for access to your camera, microphone, location, or notifications? Whether you clicked “allow,” dismissed it, or just wondered why it appeared, those permission requests aren’t always harmless. Some sites can abuse those permissions.
With Access Control, a new feature in Browser Guard, you decide exactly which websites can access your device and stop the rest. That means you choose which websites can:
Use your camera
Use your microphone
Access your location
Send you notifications
Further, not only can you control which websites have access to your devices, but you can also block websites or even require those specific sites to request permission every single time they try to gain access to your machines. You can always allow trusted sites to access your camera or location while blocking everything else.
Access Control is now available for Malwarebytes subscribers using Chrome and Edge browsers on a Windows device.
How to use Access Control
We designed Access Control to be both powerful and simple because we know every moment you spend getting set up is another moment you’re left unprotected.
How to use Access Control:
Install/Open Browser Guard: Click the Malwarebytes icon in your browser’s header
Access Dashboard: Click the Dashboard tab at the bottom of the extension panel.
Navigate to Access Control: On the left sidebar of the web page, select Access Control.
Manage Permissions: See visited websites, click “Allow” to enable or disable Malwarebytes’ ability to see visited sites.
Access Control requires some access to your browsing to protect you online
Access Control lets you choose individual sites to block and allow
This feature is rolling out in beta first, so you might see improvements and updates as we refine it. Currently, the feature works across Chrome and Edge, but will roll out to other browsers soon.
Access Control is another step toward making privacy simple and accessible. Not a subscriber yet? Check out Malwarebytes’ plans today to unlock this feature and more.
We don’t just report on threats—we remove them
Cybersecurity risks should never spread beyond a headline. Keep threats off your devices by downloading Malwarebytes today.
You have done it a thousand times. Right-click. Delete. Empty Trash. Done.
Except it’s not done. That file, your tax return, your private photos, that EmbezzlementPlan.doc… it’s all still sitting on your drive. Invisible to you, but not to anyone with a $30 recovery tool downloaded from the internet.
The problem: Your deleted files aren’t actually gone
Most users assume that deleting a file removes it permanently. In reality, standard deletion only removes the file’s reference from the file system. The underlying data often remains intact on disk until it is overwritten by other files. Think of it like tearing the table of contents out of a book while leaving all the pages intact. The operating system forgets where the file is listed, but the data itself is still there.
The space the file used gets marked as available for new data. Until something else writes over it, the original file may remain fully readable on the disk. Depending on how you use your computer, that could take days, weeks, or even months.
Recovery software exploits this. It scans your drive for data that still exists but is no longer listed in the file system. If you’re trying to recover a file you accidentally deleted, this is a lifesaver. But if you’re trying to permanently dispose of sensitive information, it’s a serious problem.
The answer: Overwrite, don’t just delete
To address this privacy gap, we’ve introduced File Shredder for Windows. It permanently destroys the files and folders you’re trying to delete so they can’t be recovered.
When you overwrite a file, you replace every single byte of its contents with new data. The original information is physically altered on the disk surface. Once overwritten, the original data no longer exists. There is nothing left to recover.
But one overwrite is not always enough. Advanced recovery techniques can sometimes detect traces of previous data, especially on older hard drives where magnetic patterns leave subtle residue. That’s why File Shredder doesn’t just overwrite once. Depending on your chosen security level, it overwrites multiple times, using different patterns each pass.
How it works
File Shredder uses DoD 5220.22-M, a data sanitization standard developed by the US Department of Defense for securely destroying classified data stored on computers.
The standard overwrites data using specific patterns:
Zero-fill passes (every byte set to 0x00)
One-fill passes (every byte set to 0xFF)
Cryptographically random data passes
Verification to confirm the overwrite was successful
Why these specific patterns? Zeros and ones represent binary data. Random data adds unpredictability. By cycling through these patterns multiple times, the original magnetic or electronic state of the storage medium is thoroughly disrupted, making forensic recovery impractical.
When File Shredder finishes, that file isn’t just deleted. It’s gone.
Three levels of shredding
File Shredder overwrites a file before deleting it, helping prevent recovery after it is removed. This is most meaningful on traditional hard drives, where overwrite passes are more direct and predictable. On SSDs, storage works differently, so multiple passes do not provide the same level of assurance. File Shredder offers a few levels so you can choose the right balance of speed and confidence for your device and use case.
Not every file on your computer will need military-grade destruction. Shredding takes time because each pass means reading and writing the entire file contents. File Shredder gives you three options, so you can balance security against speed.
Basic (1 Pass)
The entire file is overwritten with zeros. This is the fastest option and is effective for everyday file deletion where you want to prevent casual recovery. If someone ran a recovery tool after a Basic shred, they would find nothing but empty data where your file used to be.
Best for: Temporary files, downloads you no longer need, general cleanup where speed matters.
Thorough (4 Passes, DoD 5220.22-M)
The file is overwritten with zeros, then ones, then random data, then zeros again. After these passes complete, File Shredder performs a verification step, reading the file back to confirm the overwrite patterns were successfully written. This catches any disk errors or write failures that might have left original data intact.
Best for: Financial documents, tax records, personal identification documents, medical records, anything you would not want exposed in a data breach or if your computer were stolen.
Paranoid (8 Passes, Extended DoD 5220.22-M)
This runs the full zeros-ones-random-zeros sequence twice, with verification after completion. The additional passes provide extra assurance against advanced forensic recovery techniques.
Pattern: Zeros > Ones > Random > Zeros > Zeros > Ones > Random > Zeros
Best for: Highly confidential business data, legal documents, intellectual property, anything subject to regulatory compliance, or situations where you need absolute certainty.
A note on SSDs
Solid-state drives (SSDs) behave differently from traditional hard drives because wear leveling and flash translation layers may redirect writes to different physical blocks. This means overwriting a file once or multiple times does not guarantee the original data was overwritten. Multi-pass shredding methods were designed for HDDs and are less predictable on SSDs.
How to get started
File Shredder lives in the Tools section of your Malwarebytes desktop software, alongside other system utilities. We designed it to be straightforward while ensuring you understand the permanence of what you are about to do.
Select
Choose individual files, entire folders, or multiple items at once. File Shredder automatically protects critical system files, so you cannot accidentally shred something that would damage Windows or your Malwarebytes installation. Before anything happens, you’ll see a complete list of every file that will be shredded, with full visibility into file names, locations, and sizes.
Confirm
Clear warning dialogs explain that destruction is permanent. You must explicitly acknowledge before anything is destroyed. Once a file is shredded, it cannot be recovered.
Shred
Choose your level (Basic, Thorough, or Paranoid) and confirm. During shredding, you’ll see real-time progress showing:
which file is being shredded
how far along the process is
estimated time remaining
You can pause or cancel the job. However, once File Shredder starts working on a file, it finishes shredding that file before stopping. This prevents files from being left in a partially overwritten state, which could leave them corrupted or difficult to delete properly.
Done
When shredding completes, File Shredder shows a report listing every file that was successfully destroyed. You’ll also receive a notification confirming the job is finished.
How File Shredder handles large files safely
Shredding large files or deeply nested directories can use a lot of CPU and resources on your machine. To balance security with performance, the implementation includes:
Buffered write operations for efficient disk access
Chunked overwrite processing to handle large files without excessive memory use
Recursive folder shredding that processes entire directory trees
Cancellation handling where feasible, without leaving partial data behind
Error reporting so you know if any file could not be shredded (for example, if it’s open in another application)
Preventing accidental shredding
Building a feature that claims to permanently destroy data is a serious responsibility. We did not just write the code and assume it worked. We tested aggressively.
Because shredding is irreversible, the UI incorporates multiple safeguards before execution:
Explicit file or folder selection
Clear warnings about permanent deletion
Confirmation prompts before shredding begins
Shredding prevention on protected system paths or Malwarebytes files
When you’re done with a file, it should really be done
For too long, “delete” has mostly meant out of sight, not out of existence. File Shredder changes that. By securely overwriting files before removing them, it helps ensure your sensitive data stays private even after you delete it.
We don’t just report on threats—we remove them
Cybersecurity risks should never spread beyond a headline. Keep threats off your devices by downloading Malwarebytes today.
Most of us think deleting a file means it’s gone for good. But “delete” on a Windows device often just means “out of sight,” not necessarily “out of reach.”
That’s where File Shredder, a new feature within Malwarebytes Tools for Windows, comes in. File Shredder lets you securely delete files from your hard drive or USB drive, so the files are not just removed—but completely unrecoverable, even with specialized recovery software.
What File Shredder does differently
When you delete a file by placing it in your Recycle Bin and emptying the contents, your computer typically removes the reference to it—but the data itself can remain on the drive until it’s overwritten. That leftover data can sometimes be recovered using basic digital tools, some of which can even be downloaded for free online. These data traces pose a problem if the file you want to delete includes personal, financial, or other sensitive information, like tax documents, scanned IDs, contracts, or anything else you would like to remain private forever.
File Shredder goes beyond standard deletion by instead permanently overwriting the file data, ensuring it can’t be reconstructed or recovered. Once a file is shredded, it’s gone for good—no undo, no recovery, no second chances.
That makes File Shredder especially useful when:
You’re cleaning up sensitive files before selling or donating a device
You need to securely remove files from a USB drive
You’re minimizing digital clutter without leaving data behind
You want peace of mind that private files stay private
How to use File Shredder
File Shredder is designed to be powerful without being complicated.
To use File Shredder:
Open the Malwarebytes app and select the “Tools” icon from the lefthand menu (the screwdriver and wrench icon)
From this menu, find and click on “File Shredder”
Once here, you can manually add files or folders to the list and then click on the button “Delete permanently”
You will be asked to confirm your request before File Shredder deletes the files
The Malwarebytes Tools screen
Manually select files and folders for deletion
Confirm your deletion requests
Done!
After your files are deleted by File Shredder you can move on, confident that the data can’t be accessed again.
Protection means your data is in your control
Cybersecurity isn’t just about blocking threats—it’s also about giving you control over your own data. File Shredder provides a way to do exactly that, helping you close the door on files that you no longer want on your devices.
Because when you’re done with a file, it should really be done.

This article explains why Chrome’s “preloading” feature can cause scary-looking blocks in Malwarebytes Browser Guard and how to turn it off.
Modern browsers want to provide content instantly. To do that, Chrome includes a feature called page preloading. When this is enabled, Chrome doesn’t just wait for you to click a link. It guesses what you’re likely to click next and starts loading those pages in the background—before you decide whether to visit them.
That guesswork happens in several places. When you type a search into the address bar, Chrome may start preloading one or more of the top search results so that, if you click them, they open almost immediately. It can also preload pages that are linked from the site you’re currently on, based on Google’s prediction that they’re “likely next steps.” All of this happens quietly, without any extra tabs opening, and often without any obvious sign that more pages are being fetched.
From a performance point of view, that’s clever. From a privacy and security point of view, it’s more complicated.
Those preloaded pages can run code, drop cookies, and contact servers, even if you never actually visit them in the traditional sense. In other words, your browser can talk to a site you didn’t consciously choose to open.
Malwarebytes Browser Guard inspects web traffic and blocks connections to domains it considers malicious or suspicious. So, if Chrome decides to preload a search result that leads to a site on our blocklist, Browser Guard will still do its job and stop that background connection. The result can be confusing: You see a warning page (called a block page) for a site you don’t recognize and are sure you never clicked.
Nothing unusual is happening there, and it does not mean your browser is “clicking links by itself.” It simply means Chrome’s preloading feature made a behind-the-scenes request, and Browser Guard intercepted it as designed. Other privacy tools take a similar approach. Some popular content blockers disable preloading by default because it leaks more data and can contact unwanted sites.
For now, the simplest way to stop these unexpected block pages is to turn off preloading in Chrome’s settings, which prevents those speculative background requests.
How to manage Chrome’s preloading setting
We recommend turning off page preloading in Chrome to protect your browsing privacy and to stop seeing unexpected block pages when searching the web. If you don’t want to turn off page preloading, you can try using a different browser and repeating your search.
To turn off page preloading:
In your browser search bar, enter: chrome://settings
In the left sidebar, click Performance.
Scroll down to Speed, then toggle Preload pages off.
