It is known that ransomware such as Chekyshka is capable of eliminating Shadow Volume Copies of encrypted data just to harden the decryption process for their victims. Indeed, it is very hard to recover files after such attack is no official decrypter is released. However, you still should not follow any ransom demands from these people.

Chekyshka ransomware spreaders might be not only hackers but scammers also. What they will supposedly do is collect money from you and run off while you remain hopeless without any decryption solution. Our recommendation would be to try some data recovery tips that we have provided below and do not forget to backup your data next time.

However, Chekyshka ransomware removal should be completed first as the recovery methods will not work if the cyber threat is still active.

Email spam campaigns are likely to be filled with malware

There are a lot of locations on the Internet sphere that can be misused for malware distribution. However, email spam is the most popular technique for spreading ransomware and similar infections.[3] Crooks who deal with such business tend to drop suspicious-looking email messages that contain infectious attachments.

Usually, such emails can be recognized by a bunch of grammar and style mistakes. Also, the sender's email often appears to be something rogue. However, in some cases, criminals might pretend to come from reputable organizations. If you receive such message and are not sure about its safety, you should bring anti-malware for help.

We recommend scanning each clipped document or file that comes with the email just to be sure that nothing malicious is hiding there. Moreover, avoiding peer-to-peer networks, gambling and porn websites will also decrease the possibility of catching a ransomware infection through third-party sources.
