Since the vast popularization of ransomware campaigns seen in the past couple of years, security researchers have been trying to establish ways to prevent these crypto virus infections. In addition to the best free anti-ransomware tools, brand new (anti-ransomware) solutions such as the CryptoDrop project appear on the market.

The anti-ransomware project was recently introduced during the IEEE International Conference on Distributed Computing Systems in Japan.
What Is CryptoDrop and How Does It Work?
CryptoDrop, which is currently available only on Windows watches over the user’s filesystem for signs typical for crypto virus infections. Such signs include:
- Encryption processes;
- Drops in available entropy (random data collected by an operating system or application for use in cryptography);
- Changes in file types (file extensions).
In case CryptoDrop makes a detection it will stop the infection/ encryption process and alert the user.
According to the minds behind the anti-ramsomware project, a working solution should confront the threat once it hits the system. CryptoDrop even lets the ransomware encrypt a few files before it takes any actions against it.
Nolen Scaife, a UF doctoral student, part of the team that came up with the solution explains that:
Our system is more of an early-warning system. It doesn’t prevent the ransomware from starting… it prevents the ransomware from completing its task… so you lose only a couple of pictures or a couple of documents rather than everything that’s on your hard drive, and it relieves you of the burden of having to pay the ransom.
During the tests on a PC with 5,100 files, CryptoDrop succeeded in detecting and stopping ransomware in its early stages. The research team tested their system against 492 ransomware pieces.
In other words, the solution doesn’t prevent ransomware from getting to a system but it prevents it from encrypting all available user data. CryptoDrop can work alongside a classical anti-virus program. In fact, it’s recommended that you install and keep an anti-malware tool installed and running at all times.
Spy Hunter scanner will only detect the threat. If you want the threat to be automatically removed, you need to purchase the full version of the anti-malware tool.Find Out More About SpyHunter Anti-Malware Tool / How to Uninstall SpyHunter
