Ransomware is a particularly nasty kind of malware which encrypts your files and holds them ransom until you make a payment. In this article, we explain what ransomware is, how it works and which software can help you protect against it best.

What is ransomware and why should you protect against it?

Ransomware is a kind of malware which locks you out of your device or encrypts files on it, preventing access until a sum of money is paid. This tricky malware can be delivered via Trojan, which a user may download by accident thinking it is another file, or it can spread without any user action, as in the case of WannaCry.

WannaCry spread very quickly and was perhaps the most high profile recent example of ransomware. It affected 300,000 computers in over 150 countries by taking advantage of a vulnerability in Windows which was leaked from the NSA. Another example of ransomware is Cerber, which infects your system via Trojan horse, then encrypts your files and asks for payment.

You can commonly catch it by downloading pirated software or movies, and then only the hackers have the ability to decrypt your files. Other examples of nasty strains of ransomware include CryptoLocker, Petya, Bad Rabbit, AES-NI and Osiris, among others.

Individuals and businesses need to protect their data against this threat with anti-ransomware software, as it is growing more prevalent and costly each year. This year, there has been a 400% increase in new strains of ransomware. That means protecting against known threats alone is not enough. You also have to protect against emerging threats and zero-day attacks.

The average ransom demanded in 2017 was $1,100. Even if you already have an anti-virus software, it helps to have an extra layer of protection against this specific type of malware, because if you don't, it can cost you thousands of dollars in either ransom money or damage to your files and systems. Luckily, there are plenty of affordable and free solutions out there for preventing ransomware attacks and keeping your data safe.

What is the best software to protect against ransomware?

There are a lot of options for protecting your PC against ransomware attacks, but we recommend Acronis Ransomware Protection. It's a free application with a wide range of benefits, including not just active prevention, but also file backup and recovery.

By monitoring the behavior of your system in real time, it can stop attacks from known ransomware (like WannaCry, Osiris and Petya) and from new ransomware which hasn't ever been seen before, also known as zero-day attacks.

Here's how it works: If a suspicious process starts trying to encrypt your files or infect your system, Acronis will stop the activity and notify you. It will then give you the option to either block the activity permanently or let the suspicious activity continue if it was a false alarm, for example, if you were encrypting your own files on purpose.

It doesn't stop there. If malware does manage to damage or encrypt your files, they can be restored from a local cache on your computer. In addition, Acronis offers 5 GB of free cloud storage, which updates regularly, so you can keep your most critical files backed up securely in the cloud, too.

Why choose Acronis?

There are other solutions out there for protecting against ransomware, like Bitdefender's free Anti-Ransomware Tool, RansomFree by Cybereason, Trend Micro RansomBuster or even Avast Free which offers ransomware protection and an antivirus for free. But, Acronis is unique. In addition to active prevention, Acronis' solution focuses on data protection and data recovery. By offering a cache of your data locally on your computer and a backup in the cloud, you have twice the protection against not only ransomware, but any other threats to your data, including yourself.


If you accidentally break your laptop, delete your most important Dropbox folder, download a virus or have another unfortunate incident, your data is still safe with Acronis. That's the power of data protection, and Acronis is offering its ransomware protection software for free to show users its importance.

Acronis Ransomware Protection doesn't compete with your antivirus, so you're not choosing between solutions, you're getting an extra layer of protection, so there's no reason not to download it. It is meant to be used alongside an antivirus, so you should already be running Windows Defender on your PC at a minimum, plus something from the likes of Bitdefender, ZoneAlarm or another antivirus software. As such, Acronis does internal testing to make sure its solution is compatible with all major antivirus solutions.

2. In the Active Protection section, it shows Monitored processes which you should keep an eye on as potential threats and Safe processes which you don't need to look too closely at. Monitored processes show up as blue in the timeline to the right, while Safe processes are green. Red obviously means a more clearly malicious process has been detected. Clicking Manage processes will bring you to a list of suspicious processes, and you can choose to either block or trust them from that screen.
