What is ransomware?
Ransomware is a type of malicious software designed to block access to a computer system or computer files until a sum of money is paid. Most ransomware variants encrypt the files on the affected computer, making them inaccessible, and demand a ransom payment to restore access.
How do you get infected with ransomware?
Most ransomware is delivered via email that appears to be legitimate, enticing you to click a link or download an attachment that delivers the malicious software. Ransomware is also delivered via drive-by-download attacks on compromised websites. Some ransomware attacks are also sent using social media instant messages.
Am I a target of ransomware?
Unfortunately, yes.

Currently, ransomware is one of the largest cyber security threats, costing individuals and organizations over $1,000,000,000. Ransomware does not discriminate and is becoming even more advanced.

I have an antivirus installed on my PC. Am I protected against ransomware?
Antivirus provides some protection against some strains of ransomware. Unfortunately, they fail to defend against the latest, most advanced strains of ransomware.
What is RansomFree?
RansomFree is a free ransomware protection software, created by Cybereason. RansomFree detects and stops ransomware from encrypting files on computers and servers.
What is unique about RansomFree?
RansomFree is a behavioral anti-ransomware tool for detecting and stopping never-before-seen ransomware. RansomFree protects against local encryption, the encryption of files on network or shared drives, and catches stand-alone ransomware programs as well as fileless ransomware.
Can I see a demo of RansomFree?
Why doesn't RansomFree cost me anything?
Cyber criminals have been far too successful leveraging ransomware to make money off victims. Cybereason aims to stop this trend. As a cybersecurity company, we believe it’s our mission to help everyone – individuals at home, small businesses, and large enterprises. Our free tool is here for you to protect yourself from malicious attackers. We offer it for free and will keep it free.
Is this a free trial and I will need to pay later?
No. RansomFree is a free tool. You will not be asked to pay a fee or subscription at any time.
How does RansomFree work?
Cybereason RansomFree watches the way applications interact with files, and when it detects ransomware behavior, it stops it immediately before the files are encrypted. Cybereason RansomFree uses pure behavioral detection techniques and does not rely on malware signatures.

Cybereason RansomFree deploys bait files strategically placed where ransomware often begins its encryption. The solution watches the way applications interact with files, and when it detects ransomware behavior, it stops it immediately before the files are encrypted.

Will RansomFree protect all users on my computer?
Yes. RansomFree protects against ransomware regardless of who is using the computer.
Does RansomFree protect all my drives?
RansomFree  protects all fixed and removable network drives, such as USB or USB-connected hard disks.
Which ransomware strains does RansomFree protect against?
RansomFree protects against 99% of ransomware strains. It was found effective against dozens of ransomware types, including the notorious Locky, Cryptowall, TeslaCrypt, Jigsaw and Cerber.
Will RansomFree protect me against future ransomware strains?
Yes. RansomFree was developed to do exactly that. Ransomware strains that will be developed in the future will most likely exhibit a similar behavior to today’s ransomware strains and will be detected and stopped by RansomFree. RansomFree will evolve as ransomware evolves.
Do I need RansomFree if I already have an antivirus installed?
Yes. Antivirus solutions detect only some ransomware strains, failing to protect against the most advanced types of ransomware. In fact, a Cybereason survey showed that two-thirds of ransomware victims were infected even though they had antivirus solutions in place.
Will RansomFree interfere with my current antivirus or other security software?
No. RansomFree is designed to work alongside any antivirus solution or other security software and not interfere with its operation.
Does Cybereason collect any data about me?
Cybereason collects anonymous statistics to help improve RansomFree. For example, when ransomware is detected, RansomFree will automatically upload the file to our secured servers for the purpose of further research by Cybereason Labs. Using this information, Cybereason will continue developing RansomFree with new and improved detection methods.
Which operating systems does RansomFree support?
At this time, RansomFree is supported on Windows 7, 8, 10, 2008 R2 and 2012 R2.
Can I install RansomFree on Mac/iOS devices?
At this time, Cybereason RansomFree runs only on Windows computers and servers.
Can I install RansomFree on tablets, phones or iPad?
You can install RansomFree on any device that supports Windows. At this time, RansomFree is not running on Android or iOS.
How much space on my hard-drive does RansomFree require?
RansomFree requires about 100MB.
How much CPU resources does RansomFree use?
RansomFree uses very little CPU resources, which will have no effect on your PC performance.
What will happen when I get attacked by ransomware?

I’ve been hit by ransomware and my files have been encrypted! Can RansomFree remove ransomware that is currently present on my machine and restore my files?
If you are a victim of a ransomware, and your files are currently encrypted, our advice for you is to contact the authorities to determine next steps. RansomFree is designed to protect against ransomware infection. It is not able to decrypt files that have already been encrypted by ransomware.
RansomFree just alerted me that ransomware activity was detected! What do I do now?
If you have been hit by ransomware, RansomFree will immediately alert you and ask if you want to stop and clean the threat.


If you are unsure about the threat, we recommend you click “Yes” to stop and clean the threat.

Please note that RansomFree was designed to stop ransomware from encrypting files. That’s why sometimes ransom notes or other visual effects generated by the malicious software, such as a countdown timer, may still appear but will do no harm.

In any case, we recommend you verify your files and ensure that they have not been encrypted. Information about which files were affected, if at all, appears in the RansomFree alert. Encrypted files usually have their file extension (suffix) changed.

Will RansomFree protect me against recurring attacks?
Yes. You are protected against other ransomware attacks.

If you are hit again by the same type of ransomware already detected by RansomFree, RansomFree will follow your previous actions: if you chose to stop and clean the threat, RansomFree remembers your selection, and will automatically stop its execution again. But, if you chose to let the threat run, RansomFree will stop alerting you (for that specific file) and will let it run again. If you’d like to clear your selections at any time, right-click the RansomFree icon located in the system tray and choose “Clear history.”

What is WannaCry?
WannaCrypt 2.0 (WannaCry, WannaCrypt0r) is the worm used in the most recent, widespread ransomware campaign, which started May 12th, 2017.

What does WannaCry do to your computer?
WannaCry encourages users to download and execute a malicious file. Post-execution, WannaCrypt encrypts 166 file types on the victim’s computer and posts a message demanding Bitcoin payment in exchange for decryption.
Who has been affected?
Victims of this campaign are spread across more than 100 countries, hitting more than 200,000 systems, including major health organizations, energy companies and a Spanish telecommunication provider. The British National Health Service (NHS) was particularly impacted with 40 of its hospitals and subsidiaries infected.
Does RansomFree protect against Petya/NotPetya?

RansomFree Version has been updated to detect and prevent the Petya strain of ransomware, as well as other MBR-based ransomware.

You can check for the update by right clicking the Cybereason RansomFree icon in the system tray and choosing “Check for updates”.

We recommend restarting the machine after upgrading to the latest version.
