This is a virus that attack and lock the files of any system and request for ransom to provide access to the files. This is stated to be the ransom of djvu ransom family which has got lot many versions and the first attack happened in the year 2016. Till now this is attacking the system and further the same is recovered with the backup and going for the recovery tools weren't found effective. It is good to be on the safer side having a backup, so that even if something goes wrong the recovery can be made with ease. Next thing is not to open unwanted e-mails that are from unknown users. Most of the spread happening through the emails.

I came across this virus reading the term Cryptovirus. I don't know for what reason this has been termed as cryptovirus.

I think you forgot what is this relevant to crypto community, it's because once you machine is infected, it will ask ransom to be paid in bitcoin BTC, (just like the rest of other malware and ransomware). Again the rule of thumb is, specially if you are a crypto enthusiast.

- Never click on suspicious links
- Always update your OS and Anti-virus
- Back up your files
- Do not download pirated programs
- Stay away from torrents, if you can't, you should use a different machine and not your crypto activity desktop/laptop.

This should be posted in Scam Accusations or Meta. With that out of the way, the best thing that you can do to a ransomware if you are an individual is to not comply with the request no matter what, most ransomware does not have access to your data, they are just locking you out of the computer. A good backup for your computer will solve the problem but that is what most victims weakness lies at, they do not have one or have a time to get one. My advice to all of you, if you are handling raw and sensitive data, always get it on backup. Do not worry that much about this ransomware because most attackers are switching from phishing to spearphishing attacks which are companies that pay bigger when it comes to data compromise.

Seems like the number of ransomware are increasing day by day. With crypto rising, they are asking for ridiculous amounts of BTC to decrypt the victim's data. We need to be more careful.

Basically there's a big chance that even if one pays the ransom, still won't get his files recovered.
So using backups (a 1-2 TB external HDD is not that expensive and may be just what you need for this), avoiding to click every link and installing a good enough antivirus are the first rules.
Torrents can indeed be infected, but on the other hand many download only movies from torrents, hence the torrents rule could be improved in the post made by @TravelMug

Quite often ransomware with different methodologies are getting into existence and are spread around. To stay safe from these kind of attacks, the right choice is to have an antivirus that is up-to-date. Having an antivirus and back-up is the primary thing, and apart from this user should be aware not to click or enter any page through unknown links. Nowadays Spread through email spams is the most commonly followed one.

basically if we connect online, the word "scure" is almost non-existent.
always backup data regularly is the main key. if possible separate online and offline devices.
