Unless you’re currently running a computer completely disconnected from the web, you’re going to need protection against viruses and malware. If you’re landing on this page, there’s a good chance you fit one (or more) of the following:
- You, a family member, or a friend installed a virus and you’re now looking for how to get rid of it inexpensively
- You just got a new computer that you want to protect against viruses
- You’re simply tired of paying high prices for virus and malware removal and protection
Even if none of those descriptions quite fit, we’ve still got you covered. This list explores some of the best free malware and virus removal tools currently available to consumers. We’re not dealing with low-quality, fly-by-night software here either.
Best free virus and malware removal tools
Of the many options you could download, we trust the following free malware removal tools:
- Comodo Free Anti-Malware BOClean: Surprisingly easy to use malware removal tool
- Adaware Antivirus Free: Offers a well-rated AV scanning engine and real-time protection
- Norton Power Eraser: Designed specifically to identify and delete deep-rooted malware
- RegRun Reanimator: A human-powered service that offers a personalized malware removal approach
- Bitdefender Antivirus Free Edition: Award-winning free version of Bitdefender’s popular tool
- eScan Anti-Virus Toolkit: Requires no installation; can be run directly from a USB to help clean infected computers
- Avira Free Antivirus for PC: A traditional AV tool with a surprisingly large number of free features
- FreeFixer: Lightweight tool with few features, but effective for its purpose
- SUPERAntiSpyware: Impressively loaded free malware removal tool
We fully vetted each program against a set of rating criteria of our own. Among the most important factors we considered with each of these is how they define “free.” Whereas some software only offer free trials, or “free” virus removal tools that don’t work unless you pay up first, all of the options on this list are legitimately free-to-use and can be used to remove viruses and malware without paying a dime.
We’ve found that some of the best free malware, rootkit, and virus removal tools come from highly respected companies in the software security industry.
Our software list below covers only Windows computers. If you’re a Mac user looking for virus and malware protection, please check out our article on the best Mac antivirus programs.

It’s important to note that all free virus and malware removal tools will have some limitations over paid versions. For example, some free software may not remove all forms of viruses, including certain types of spyware. And most free antivirus tools are feature-limited compared to their paid alternatives, so they won’t include advanced features like anti-tracking browser extensions. While free tools can get the job done most of the time, there may be an occasion that requires just a bit more *umph* than a free tool will provide.
1. Comodo Free Anti-Malware BOClean
Comodo is a leading brand in internet security. Not only does the company offer a large suite of security software, it’s also one of the more respected dealers in SSL certificates for websites.
Comodo offers their Free Anti-Malware BOClean software without any strings attached. Unlike some of the other options on our list, you’re not getting a slightly neutered version of a paid option. Instead, BOClean is a standalone product from Comodo designed to rid your computer of unwanted programs.
BOClean is also one of the most feature-rich free virus and malware removal tools we’ve discovered.
With BOClean, you get all of the following features:
- Real-time malware detection and elimination
- Removes all forms of malicious files and applications (many ransomware excluded)
- Limits false alarms
- Regular malware detection reports
- Detects and deletes new and updated malware variants
- Free virus definition updates
- Hidden configuration for businesses and schools to avoid unauthorized tampering with the software
With so much packed into one small package, it’s easy to see why Comodo is a leader and the industry and why their BOClean is a popular choice. Should you want more, BOClean is included in Comodo’s Internet Security software. However, if all you need is a free tool, BOClean is hard to beat.
2. Adaware Antivirus Free
Adaware has three antivirus software tools to offer. Its two paid versions offer a large library of features, including parental controls and a digital file locker (Total package only) as well as an enhanced firewall and online shopping protection (Pro and Total versions).
However, all of that is a moot point. If you have an immediate virus problem and need action now, their free version is a solid option.
With Adaware free, you’ll get:
- Adaware’s award-winning antivirus tools
- Real-time protection against viruses
- Download scanning to protect your computer against threats
Contrary to the name, Adaware offers more than just adware removal. Perhaps the biggest limit to this program is the fact that you don’t get any tech support with the free version. You’ll need to upgrade to the paid Total or Pro versions in order to access any real-human support should things go wrong with the software. There is a forum and an FAQ section on the site, but from our experience, these are often unhelpful.
Overall, Adaware really is a no-frills antivirus and malware removal solution. If all you need is something simple and free, it’s a good option to entertain.
3. Norton Power Eraser
There’s a very good chance you’ve heard of Norton. Their primary paid option, Norton Security, not only received top marks from AV-Test, the independent testing lab gave it a coveted “Top Product” stamp of approval.
By consequence, Norton’s internet security measures are fairly trustworthy. That includes their Power Eraser, which takes some of the winning security methods applied to their paid software and packs them into a powerful malware removal tool.
Note that Power Eraser is specifically designed for “crimeware,” e.g., ransomware or other identify-stealing viruses. Norton also claims that their Power Eraser tool is designed to get rid of viruses that most other programs won’t get.
Power Eraser is feature-limited given its somewhat targeted purpose. That said, it has a fairly healthy list of scanning functions, which include:
- Scanning for risks (viruses, malware, etc.)
- Unwanted programs scanning (PUPs)
- Single file or folder scanning
- System scanning
- Multi-boot scanning
- The option to undo a previous fix
This tool is actually fairly aggressive, although relatively light on system resources, given its singular purpose. However, that aggression means it may result in a number of false alarms. If you opt for Power Eraser to get rid of your virus or malware problem, make sure to carefully review the report before fully deleting anything. Certain types of software, including VPN software or other virus software, may get wrapped up in Norton’s sticky snare.
4. RegRun Reanimator
RegRun Reanimator from Greatis Software takes a vastly different approach to malware and virus removal. Greatis expressly states that RegRun is not an antivirus software tool. In fact, unlike most of the other options we’ve listed, RegRun Reanimator does not include real-time protection.
Instead, RegRun Reanimator is designed to remove:
- Some rootkits
That’s where its similarity with antivirus programs ends. When you run Reanimator, it creates a log detailing what viruses it’s discovered on your system and where they are located. Users then send that log file to RegRun’s tech support team which analyzes the file and sends back another file that executes the cleaning and virus removal produces through the REAnimator software.
Sound complicated? It is, at least compared to more common AV tools. But RegRun Reanimator is one of the only options available that puts a human touch on the virus removal procedures. That said, if you need something more immediate, RegRun Reanimator may not be for you. The company says it takes 1-2 days to get a response from tech support with your executable file.
RegRun does utilize a more traditional antivirus software option through its Security Suite. The Reanimator is what the company describes as a “function limited version” of their commercial software.
Consider RegRun Reanimator an option if the other more traditional virus removal programs fail.
5. Bitdefender Antivirus Free Edition
Bitdefender is an interesting option. The highly respected internet security company not only has a Top Rated stamp from AV-Test comes highly rated by AV-Comparatives as well. The free software offers a large array of free tools alongside its paid antivirus suite. While the paid version is particularly worthy of attention, the free tools are capable of standing on their own.
Bitdefender Antivirus Free Edition highlights four features that make the program worth using:
- Powerful virus scanning and removal for viruses, worms, all forms of malware, rootkits, zero-day exploits and spyware
- Threat detection for suspicious app activity
- Website blocking (anti-phishing);
- Anti-fraud system for sites that may be potential scams
That’s not all. Should Antivirus Free Edition find malware it can’t clean, Bitdefender may still have a virus removal option for you. Bitdefender offers free virus removal tools for specific named viruses. You can just type in the virus name that into the search engine and see if there’s a tool available to remove that virus.
Bitdefender does offer an upgraded version of its software for a price. However, the free version is so inclusive that it’s somewhat hard to justify paying full price for the complete software suite.
With a free virus removal tool and even more free options for particularly troublesome viruses, Bitdefender is a go-to option for troublesome malware.
6. eScan Anti-Virus Toolkit
If eScan Anti-Virus is new to you, you’re in good company. Prior to researching this piece, I’d never heard the name before either. But research interestingly reveals hidden treasures, and eScan appears to be one of them.
A small name compared to some of the much bigger enterprises on this list, eScan more than proves its worth. AV-Test gave eScan’s main product one of its few Top Rated stamps alongside high ratings for performance and functionality. The Anti-Virus Toolkit offers many of eScan’s virus removal tools and offers them free for users trying to save a buck.
eScan Anti-Virus Toolkit is purely a scanner and removal tool. The program takes up almost no presence on your system and doesn’t go through an installation process.
After you download this tool, you can use it to do the following:
- Scan for malware
- Scan individual folders
- Remove viruses
- Check network activity for unusual behavior
The benefit to this program is that you can run the software from anywhere, including a USB flash drive. That makes eScan Anti-Virus Toolkit worth having on a separate flash drive just in case you get a virus that shuts off access to your programs.
We highly recommend Anti-Virus Toolkit as a viable option to add to your virus and malware removal toolbox.
*Note: eScan has a primary antivirus program that offers a free, limited trial. This is NOT the same thing as the toolkit, and is somewhat difficult to locate on their website. Use the above link to go there directly. Otherwise, you can find the Toolkit under the “Support” section from eScan’s main homepage.
7. Avira Free Antivirus for PC
Avira is fairly clear in what if offers. The “free forever” version of its software provides all of the following features:
- Quality malware and virus scanning and removal tools
- Real-time protection
- Protection against ransomware
- Privacy protections to secure your personal data
With Avira, scanning occurs in the cloud, which helps identify unknown viruses and computer exploits, disregarding the need for a downloaded library of virus definitions (which Avira does also include).
Avira Free Antivirus for PC can also identify and remove potentially unwanted programs (PUPS), also known as potentially unwanted programs (PUAs).
Negatively, Avira helps support the free version of its program by including ads.
Should you decide you want a little bit more out of Avira, or just want to do away with the ads, a paid subscription to Avira Antivirus Pro may be up your alley. Not only does the paid version remove ads, it also allows you to install the program on up to 5 devices with the same license, alongside guaranteed phone and email support.
Avira Free Antivirus for PC offers an award-winning option with a high-powered virus removal tool.
Those who don’t want something too complicated might want to consider the considerably lightweight FreeFixer AV tool.
That said, FreeFixer takes a rather heavy-handed approach. Instead of distinguishing between wanted and unwanted programs or files, FreeFixer will offer a list of potential malware. It’s then up to the user to go through the list and delete the bad ones.
This AV tool focuses its sights on:
- other forms of potentially unwanted programs (PUPS)
Because this service gives you a list of every PUP it identifies, make sure to double-check each file that comes up in the scan before removing it. Accidentally removing legitimate files can damage your Windows operating system or apps. If you want the option to quarantine and restore deleted files, you’ll need to pay $9.95 for the Pro version.
Although the name says “anti spyware”, the SUPERAntiSpyware AV tool is actually far more encompassing than that. Not only can you use this tool to remove spyware, but you can also run its scanner to check for and remove most other forms of malware.
There’s both a free and paid pro edition with this tool. However, the free edition offers thoroughly robust features, including:
- Detection and removal of malware, spyware, adware, keyloggers, ransomware, and more
- Multi-dimensional scanning
- Process interrogation that examines system processes for potential malware
Although there’s no real-time scanning available for free, the scans provide free malware identification and removal. Updates aren’t automatic with the free version, either, but you can still update the virus definitions manually. The only features missing from the free version are different scanning options (such as scan scheduling or quick scans) and email notifications for completed scans.
