Ransomware viruses work by making changes to the Windows startup, so the virus will always start along with the computer. It does this by modifying the registry keys of Windows.
The virus will then scan the system and start searching for audio files, pictures, documents, databases. Most files that users would value and would want back are of this type, which means that victims would be more likely to pay the ransom.

Czech ransomware virus – Conclusion

The virus is relatively new, and there’s no decrypter released as of yet. Victims of the virus shouldn’t pay the ransom, as that will add fuel to the fire. Ransomware scammers make too much money as it is. The creators of the Cerber ransomware make close to a million dollars a year. This type of scamming is one of the biggest threats on the Internet, and we urge users to combat the threat by taking the necessary steps to avoid infection (a.i. anti-virus programs, anti-malware tools, and most importantly, caution.)
