Malwarebytes launches free scam link checker ahead of major shopping events

Malwarebytes has launched a free web tool called Scam Link Check that allows users to verify whether a website link is safe before clicking it. Users paste suspicious URLs into the tool at malwarebytes.com/scam-check/link, and it returns a safety verdict within seconds, along with explanations and recommended actions. The tool analyses links using Malwarebytes' threat intelligence ecosystem, checking for phishing pages, counterfeit stores, and malicious redirects. It provides a screenshot of the website so users can preview it without visiting, and offers an option to report suspicious sites. The launch comes as Malwarebytes research found that 85% of people say they can no longer reliably distinguish scams from legitimate content. The tool is part of Malwarebytes' broader anti-scam ecosystem, which includes similar free tools for checking phone numbers and personal data exposure.

New Browser Guard features add protection before and after you click.

New Browser Guard features add protection before and after you click. Most of Malwarebytes click on search results without knowing much about the website Malwarebytes is about to visit. And once Malwarebytes is there, it's not always obvious when something isn't quite right. Now, Malwarebytes has added two new features to Malwarebytes Browser Guard that will do even more to keep you safe online. Search Reputation gives you a quick read on your search results, before you even click on anything. And with Scam Guard Lite, you can analyze the contents of a webpage directly from the Browser Guard extension in Google Chrome. These new features build on Browser Guard's existing protections against scams, malware, ads, trackers, and plenty of other threats while you browse. So, from the moment you begin a search to when you land on a website, Malwarebytes has got you covered. Check a website before you click. Search results don't always make it easy to tell a legitimate website from a malicious one. Scam sites are uncannily good at imitating brands, and one misleading link can send you down a dangerous rabbit hole. Browser Guard's new Search Reputation feature gives you more information before you click. When you use Google, DuckDuckGo, Brave, or Bing, Search Reputation will display a rating alongside your search results. A green "Good" rating means the website appears safe based on Malwarebytes' reputation database, while a red "Malicious" rating tells you Malwarebytes has identified the site as unsafe. But that green check mark is only the first layer of protection. A "Good" rating isn't a guarantee that a website is safe. New threats appear all the time, and no reputation database can catalog every malicious site on the internet. For as long as you're online, Browser Guard will continue working in the background and checking for other signs of danger. It may block or warn you about a site even if Search Reputation initially gave it a "Good" rating. Already on a website? Ask Scam Guard Lite. If you're already on a website and something feels off, Scam Guard Lite can help you take a closer look. Available directly in the Browser Guard extension on Google Chrome, Scam Guard Lite analyzes the contents of the webpage you're viewing without asking you to copy a link, take a screenshot, or leave the page. Just open Browser Guard, select Scam Guard Lite, and it will immediately examine the page for signs of a scam. (The first time you use the feature, Browser Guard will download Gemini to your device to power it.) The analysis happens on your device using a large language model (LLM). And if you're concerned about privacy, Malwarebytes has got your back: Your browsing history isn't saved or sent to an AI cloud. More questions? Open the full Scam Guard. If you have other security concerns, you can open the Browser Guard dashboard and use the full version of Scam Guard. There, you can ask Scam Guard to review suspicious emails and links, or ask questions about something you've encountered online. Something feel off? Check it before you click. Malwarebytes Scam Guard helps you analyze suspicious links, texts, and screenshots instantly.

Malwarebytes for Windows 5.7.0 brings free VPN access to everyone.

Malwarebytes for Windows 5.7.0 brings free VPN access to everyone. The headline feature is one that changes the value proposition of the free tier significantly: built-in VPN access with no upgrade required. Malwarebytes has released version 5.7.0 for Windows and the headline feature is one that changes the value proposition of the free tier significantly: built-in VPN access with no upgrade required. What's new in Malwarebytes for Windows 5.7.0. Privacy VPN for Free and Standard users. Previously a premium-only add-on, Malwarebytes Privacy VPN is now available to users on Free and Standard subscriptions, including 10GB of secure browsing data every 30 days at no extra cost. Malwarebytes says the rollout is happening gradually, so if you don't see the option in your app yet, it should appear in the coming days as the feature reaches your account. Hybrid team software Why it matters: for casual users who just want occasional protection on public Wi-Fi - coffee shops, airports, hotels - this removes the biggest reason to look at a separate free VPN app. 10GB a month won't cover heavy streaming, but it's a meaningful amount for browsing, email, and light use.

As with most point releases, 5.7.0 also includes the usual round of stability and reliability fixes rolled up from the beta channel that preceded it, though Malwarebytes hasn't published an exhaustive line-item changelog for this release beyond the VPN rollout. Download. Malwarebytes for Windows 5.7.0 is available now from the official Malwarebytes download page, or via its UpdateStar listing for update tracking and version history.

Malwarebytes has pushed out version 5.6.5.306, a maintenance update to its all-in-one antivirus and anti-malware suite. The release doesn't bring flashy new features, but it squashes a handful of annoyances that were affecting real-world users, including an app-crashing bug and issues with the Scam Guard and quarantine tools. What's new in Malwarebytes 5.6.5.306. Issues fixed: * Fixed an issue causing Malwarebytes to repeatedly open and close. * Improved messaging in the modal for deleting quarantined items. * Fixed an error preventing the "Report" button from showing in Scam Guard. * Miscellaneous bug fixes. Malwarebytes 5.6.5.306 continues to ship as a full antivirus replacement rather than a simple on-demand scanner.

The company says recent versions in the 5.x line scan up to four times faster than older releases, and the app is designed to run alongside other security software as an extra layer of protection.
