The best ransomware removal tools of 2021

Ransomware is rampant in 2021: find the best tool to protect your computer

Learn about the best ransomware removal tools of 2020

Ransomware[1] is one of the most devastating cyber threats out there, and, since its first appearance in 2005, it improved the means of distribution, obfuscation and prevalence across all platforms. Crypto-malware authors started using sophisticated multi-stage infection schemes which devastated high-profile organizations, governmental institutions and even cities across the globe since 2016.

However, it is evident that contemporary society is riding the crest of technology and globalization. Likewise, it isn't going to go back to pen-and-paper. For example, imagine running a hospital or international business without technological devices and ability to transfer information between institutions. In fact, such large-scale companies or public organizations are more prone to ransomware infections since they have the ability to pay considerable amounts of ransoms in relatively short time.

While attacks against random users mostly rely on spam emails, security experts saw a rise in targeted manual attacks against companies in 2020.[2] Manual malware infection is not as efficient as it is not automated, but its much harder to predict and hackers can adapt to changes during the operation.

Therefore, the only way to protect both, individuals and institutions from financial losses is to get a professional security software which would defend networks and systems from ransomware attacks before the file-encrypting virus enters. While most of the robust anti-ransomware tools must be purchased, they have free trials for their customers to check and evaluate their effectiveness.

We have prepared a guide presenting the best ransomware removal tools of 2021 which are suitable for regular computer users as well as large corporations. Although, make sure that download the anti-ransomware software only from the official websites since scammers try to trick credulous people into purchasing fake dupes of legitimate programs[3]. Thus, we kindly ask you to be attentive.

1. Free Bitdefender Anti-ransomware tool vaccinates your computer against the cyber threats

This free ransomware removal software uses a vaccination technique[4] to protect your computer from specific ransomware families. Particularly, it helps to avoid TeslaCrypt, Locky, BTC-Locker and the original version of Petya crypto-malware. The method it uses is similar to vaccination in real life — the anti-ransomware tool tricks the virus that your computer is already infected.

Since criminals are not likely targeting to infiltrate their malicious programs on the computer which have been already infected, this ransomware removal tool actually does the job it promises to do. The thing is that reinfecting the PC might make the encrypted files undecryptable even for the hackers who created the ransomware. Thus, they try to avoid such actions to maintain even a drop of trust they have from their victims.

Bitdefender anti-ransomware tool creates a file which functions as an incentive that the targeted computer has been already infected. Likewise, deflecting the attack. However, this technique might not always work, and software developers designed it to launch at the startup and run in the background for extra protection.

Another great feature of this ransomware removal tool is that it is compatible with any computer and does not require any commercial setting. However, keep in mind that you are only protected from those four ransomware families. Therefore, it is advised to use another anti-malware software for other attacks.

Pros Cons Conclusion
Free for both, personal and business use. Cannot protect against other ransomware families and viruses. While Bitdefender Anti-ransomware tool definitely protects from original version of Petya, BTC-Locker, Locky and TeslaLocker, you must use another security software for protection against other cyber threats in general.
Protects computer from 4 specific ransomware families.
Uses effective vaccination technique.
Always operates in the background.

2. Free Malwarebytes Anti-ransomware Beta software detects crypto-malware based on the behavior

This is another free ransomware removal tool which is a great additional component to your primary security software. While it originally is one of the elements of full-scale Malwarebytes Antivirus which is offered at $39.99, users can also install the beta version free of charge.

This ransomware removal software is compatible with these operating systems:

  • Windows 10 (32/64-bit);
  • Windows 8.1 (32/64-bit);
  • Windows 8 (32/64-bit);
  • Windows 7 (32/64-bit).

Malwarebytes Anti-ransomware Beta protects its user's computer by controlling the access to important domains or specific file types. In other terms, if an unauthorized program tries to modify or reach a controlled location/file, the security software warns the user about a potential ransomware attack.

Note that most widely used programs such as Microsoft Office or Windows Components are not recognized as a threat. However, other ones turn on the red light. Fortunately, the user is able to whitelist the application with just one click as well as send it to quarantine.

Unfortunately, there might be a case where the ransomware might impersonate a whitelisted program and stealthily reach your system. For this reason, experts categorize this tool as a great extra layer of protection in addition to the primary security software.




Beta version is free of charge for personal and business use. Some files might be encrypted before the ransomware is put into quarantine. Malwarebytes Anti-ransomware Beta software is a great extra layer to your security application since it catches all cyber threats which might have slipped through the primary program.

Kaspersky Lab offers a great ransomware removal tool for free as well. Despite implications in the name which might make you think that only large-scale businesses can benefit from this program, this security software can serve for your personal use as well.

However, Kaspersky Anti-ransomware tool offers compromised file recovery in case your PC is infected with ransomware.

Another excellent feature of this security software is that even if the file-encrypting virus manages to shut down the application, it instantly reopens and starts running automatically. Although, it is wise to know that this program cannot run together with other Kaspersky applications which would be a great second layer of protection.

Pros Cons Conclusion

Can serve for individuals as well. Requires registration with sensible details.

Trend Micro has released an effective security software called RansomBuster which has not one, but multiple layers of protection against ransomware attacks. Additionally, it is free for both, regular computer users and large corporations. However, you can also get it as an extra component while purchasing Trend Micro Antivirus + Security product.

All in all, Trend Micro RansomBuster is an excellent choice taking into consideration that it is free of charge. Also, its Folder Shield does the job it promises, but it is limited to 2 folders. Moreover, some experts point out that its behavior-based detection should be improved. Thus, use it as an extra layer of protection only.

Pros Cons Conclusion
Folder Shield feature blocks unauthorized apps from accessing protected folders. Folder Shield protects maximum 2 folders. Trend Micro RansomBuster offers multiple layers of protection which helps to not only prevent ransomware attacks but also retrieve encrypted files. However, it is advised to use it as an additional security software due to necessary improvements in bahavior-based detection.
Free for everyone.
Has behavior-based detection which functions in all directories.
Creates backup copies to recover files after attack.

Zemana Anti-malware has both, free and premium versions which differ by extra features. While free version consists of smart scan and drag & drop option, full variant offers real-time protection and a deep scan as well. Another great function which is included in both variants is the ability to contact technical support 24/7.

Smart scan corresponds to the quick scan which checks only the most common directories where ransomware is used to reside. Also, it takes far less time to complete the check than the deep scan which usually examines all files on the computer.

According to the tests, this function is beneficial for those who are using free version since it is a deeper scan than the Smart scan that version provides. Also, it is considered to be the middle option for those who have the full version and eager to scan only particular files.
