The best free file and website malware scanners

The malware scanner you use could depend on the situation. For instance, you may want to check websites that you frequently visit or you may need to remove malware. With computer viruses becoming more prevalent, it’s understandable to use as much security on your devices as possible. We’ll look at some examples and use cases for our top five malware scanners.

Sucuri SiteCheck: Best for a quick website check for malware

Who it’s best for

A Sucuri SiteCheck malware scan for target.com

Sucuri is great if you want to scan websites fast and get some technical information along the way. SiteCheck, its web security scanner, shows you the IP address and website blacklist status. A blacklisted website means it is deemed unsafe, so it’s not one you want to access.

You can get a pretty clear picture when you run a web address on SiteCheck. It also informs you of the firewall status and if there’s website monitoring. In addition, it can check for redirects, iframes, and JavaScript to help you determine if a website is unsafe to use.

You’ll be able to see the malware security risk, which can help you decide if you want to continue visiting the website. That’s a great tool to have if you spend a lot of time browsing different internet sites.

What we liked

We liked how fast the malware scanner checked the website we tested. The scan only took a few seconds and gave us all the data we mentioned above. We also liked that the more technical-minded user can dig a little deeper to find out more about the website’s security. This is also a great product for someone who has a website. You can run a scan whenever you want and see if there’s anything unsecured listed.

Sucuri SiteCheck pros and cons

Pros
  • Results are fast
  • Detailed data is available
  • Users can also check websites they own
Cons
  • Some info can be more technical
  • Chatbox pop-ups after each scan can be annoying

SiteLock: Best for users who may have websites

Who it’s best for

SiteLock scan results for malware, vulnerabilities, CDN, and platform used.

SiteLock may be best for the user who has their own website and wants to check other websites for malware. If you have a website, you know how hard it can be to keep malware from bogging it down. This product not only offers malware detection, but it also displays if any plug-in vulnerabilities are showing. That is especially useful if you have a small website that doesn’t get lots of traffic. If that’s the case, the free version can give you much-needed peace of mind.

What we liked

We liked using this free tool to perform a basic scan, which gives us enough information to know the website looks safe. It’s a clean interface that doesn’t offer extra technical details. SiteLock also lets you know the platform a website uses, which can be nice if you want to know how a site was put together and if it’s known for a positive user experience. If you want a tool to check for malware without a lot of fuss, SiteLock could be a great option.

We also liked the transparency you get upfront with the product. It lets you know that the free scan may not detect if the website is entirely free of malware because it checks for external website files, unlike the paid plans that scan code and files connected to your website.

SiteLock pros and cons

Pros
  • Clean, no-frills interface
  • Lets you know the platform the website uses (e.g., WordPress, Squarespace)
  • No technical information that you may not want
Cons
  • Mostly basic reviews without in-depth search information
  • Doesn’t show if a site is blacklisted

Norton Power Eraser: Best for Windows users who don’t want to install software

Who it’s best for

Norton Power Eraser page clarifying that it only works on Windows devices.

Norton Power Eraser is best for Windows users who want to scan for malware but don’t want to install more software onto their devices. The program appeals to many users who want to save room on their computers and not bog down system resources with more software applications. Power Eraser is not available for anything other than devices compatible with Windows.

What we liked

We think the ability to use Norton Power Eraser without having to install it is a plus. Every installation takes up resources on your device, so you want to be sure you aren’t overloading it with too many programs.

The product also scans for potentially unwanted programs (PUPs) and potentially unwanted applications (PUAs), which can be a pain. If Power Eraser finds malware, it will remove it for you, so your device can be more secure.

Norton Power Eraser pros and cons

Pros
  • Runs without needing to be installed
  • Looks for PUPs and PUAs
  • Removes malware immediately when found
Cons
  • Only works with Windows
  • Since it removes suspected malware immediately, it could remove valid programs

Bitdefender Virus Scanner: Best for Mac users who want to scan apps and the entire system

Who it’s best for

Bitdefender Virus Scanner indicating that the Mac in use is clean.

Bitdefender is best for the Mac user who wants plenty of scanning options. This program lets you scan the most critical locations of your device, complete a deep system scan, or create a custom location scan. If you want an interface that’s easy to use and gives you straightforward status updates on your device security, Bitdefender Virus Scanner is a great option.

What we liked

We had a blast testing Bitdefender Virus Scanner. What we liked right away were the options you get to choose from, like the deep system scan or merely scanning critical locations if you’re more pressed for time.

Bitdefender Virus Scanner also stands out because it scans running applications while you’re on your device. Before Bitdefender scans your programs, it updates to check for any new viruses. That makes it more valuable because you get protection against the latest security threats.

With the features you get from Bitdefender, we don’t think you can go wrong with this program. If you want more security and don’t want to pay for it, this offers a lot of value without a hefty price tag. You can also get Bitdefender for Windows if you don’t use a Mac.

Bitdefender for Mac pros and cons

Pros
  • Scans running apps while you work
  • Removes or quarantines threats
  • Updates before scanning to ensure the most protection from new threats
Cons
  • Doesn’t allow you to check a URL for security issues before using it
  • Doesn’t offer phishing protection

Trend Micro HouseCall: Best for users wanting customization features with threat removal

Who it’s best for

Trend Micro HouseCall's summary after a malware scan.

Trend Micro HouseCall, from the makers of Trend Micro antivirus, is a good software for those users wanting options for Windows or Mac platforms. You can get this software for your home network, too, but that feature is only compatible with Windows 11.

It also functions with existing security software you may already have on your device. Sometimes that can be a hassle because running two similar programs can cause your device to lag. Being able to have two security systems run simultaneously gives you more protection. With HouseCall, you can remove viruses and spyware, and you can add a reminder to scan weekly if desired.

What we liked

There’s a lot to like about this program. You get custom scan options, so you can run a full scan or a quick scan. HouseCall removes any threats it finds, and you can scan your files to make sure they’re safe. Although it’s available for Windows and Mac users, keep in mind the option to use the home network feature is only compatible with Windows 11. We hardly felt that was a dealbreaker with all the features you get with HouseCall. Of course, we liked that you can use it with your existing antivirus software if you’d like. Some people prefer to use anti-malware vs. antivirus software, so you can use both with HouseCall.

Trend Micro HouseCall pros and cons

Pros
  • Works with Windows or Mac
  • Lets you run custom scans
  • Can run simultaneously with other security software
Cons
  • Home network protection only works with Windows 11
  • Some full scans may take several hours to run
