A special breed of malware called ransomware is causing more headache and damage compared to any other malware these days. A ransomware encrypts your files or locks your PC and then demands a ransom for undoing this damage. It is no more different than a criminal who kidnaps someone and then demands ransom in order to let them go. But the security experts are working day and night to defeat the encryption set by every single ransomware.
If your PC has become infected with different types of the ransomware families like TeslaCrypt or CrySiS, then you can easily decrypt the files encrypted by these ransomware families using the Ransomware File Decryptor. This tool is developed by Qihoo 360 Software company – the makers of the 360 Total Security antivirus. It is a portable tool and you can run it on any PC without having to install anything.
In the Ransomware File Decryptor, you have to select the directories that might contain the encrypted files. You can select one or more than one such directories. It automatically sets a directory for saving the decrypted files but you can change it if needed. After this you can just click on the Decrypt button and it will start decrypting all the files that it can.
After the process has finished, you can see a summary that details the number of encrypted files found and the number of files that were encrypted. Now you can check the folder where the decrypted files were saved. If this tool misses something, you can try the Kaspersky NoRansom tools located at https://noransom.kaspersky.com/.
Even though the master keys for both the TeslaCrypt and CrySiS ransomware have been made public, you would still need a tool that can use these master keys to decrypt the ransomware encrypted files. The Ransomware File Decryptor from Qihoo 360 Software can do the job for you. In addition, you may also want to install a good antivirus like Avast or 360 Security to protect your PC from malware infections in the future.
