The cryptovirus or ransomware can enter into our computer. No matter what we are trained to recognize suspicious emails. Sometimes we are tired, distracted and our level of attention is lowered. “They” are increasingly clever and good at making us make mistakes. We open attachments that we should not open. At this point, the damage is done. The virus encrypt a file at a time very quickly: we estimated that the virus is able to encrypt 10,000 files in 30 minutes. After encrypting files on your computer, it starts to encrypt the files of all network folders where able to enter: servers, your colleagues’s of computers. The damage can be incalculable. In our experience there is no anti-virus that can counter it. When the virus starts to encrypt your files, you do not notice anything until it’s too late, when everything is over: the virus manifests itself by changing the image of your desktop with a message: “All your files are encrypted . If you want to get them back you have to pay a ransom. ”
If we had realized the infection once it has started, we would have definitely lost something but we could limit the damage.
Based on these considerations, we have created a very simple program that checks the contents of your personal folders and alerts you via email if a virus is altering the content. The alert can only be sent to you or in conjunction with other email addresses. After receiving the message, turn off, without hesitation, the computer by pushing the power button: better to risk breaking the power supply, which can be replaced cheaply, rather than losing all your files.
The program is completely free and you can download it here: MECDATA DAWN OF JUSTICE. Our response to CryptoVirus.
Once installed, launch it. The program will ask you, the configuration. The only thing you need to enter is the list of email addresses that you will need to alert in case of infection.
At this point, the program starts and you can see the icon on the bar at the bottom. Through this icon you can enter again in the configuration to add or change email addresses.
For lovers of performance, This program is running 18 Mb of RAM and does not impact on the processor. It does not work on Windows XP.
We sincerely wish that there is useful, but if it were, in the last test, the scanner detected the infection only two minutes after the beginning of the same.
We suggest you install it. It does not solve, but improves.
