Rokku virus (Removal Instructions) - 2021 update
Rokku virus Removal Guide
What is Rokku virus?
Rokku virus is a ransomware-type infection that locks all important files to demand ransom
Rokku virus is another cybercriminals’ creation, deemed by security experts as extremely dangerous. It is a ransom-based program that stealthily enters the victims’ computers and encrypts the containing files.
You may have heard of such notorious programs as Locky virus, CryptoLocker, and CryptoWall, which have already infected hundreds of thousands of computers all across the world. Rokku works virtually by the same principle as the mentioned well-developed and widespread viruses.
It is spread through spam emails, like PDF, picture, or some other attachment file, posing as an important document, featuring some important-looking. If the user is tricked by the email's deceptive information and downloads the infected file, the Rokku virus is unleashed and begins its malicious processes on the victim’s computer.
Rokku ransomware bears its name of the file extension .rokku, which replaces the regular ones after the files are encrypted. This virus can lock regular photos, video files, documents, archives, and other data you store on your computer. To achieve that, it uses a very complex RSA-3072 algorithm, which cannot be unlocked without a decryption key which is stored on some remote server out of the victim’s reach.
Rokku virus is a dangerous infection that encrypts all important files on your computer.
After the files are encrypted the virus creates .txt or HTML file named README_HOW_TO_UNLOCK.TXT in which the victim can find the information about what happened to the PC and instructions on how to unlock the files. To retrieve the data, you must purchase the decryption key from the virus creators. This is how this fraudulent profit-making technique earns its name as a ransom-based virus.
The ransom amount developers of the Rokku virus demand for the decryption key is not extremely large, compared, for instance with the Locky virus, which has dwindled over $17,000 from one unlucky hospital in Hollywood. You may be granted access to the file decryptor for only 0,2408 BTC virtual money, which equals around $100.
However, it is not advisable to purchase anything from these cyber crooks because you might be scammed and lose not only your files but your money as well.
What is more, you also risk contaminating your system with even more viruses if you decide to visit the suggested zvnvp2rhe3ljwf2m.onion website, since it can only be accessed through the anonymous Tor network, favored by hackers, scammers, and other internet criminals.
If you are not willing to pay the ransom and rather keep your computer’s system healthy, you should remove Rokku virus from your computer as soon as possible. To delete the virus, please use a reputable antivirus tool to ensure the most effective removal. We recommend installing SpyHunter 5Combo Cleaner or Malwarebytes security program.
Only after a successful Rokku removal you can try to recover the files using backups. If you don’t have copies, do not lose hope. At the end of the article, we provide some tips on how to recover at least some of the files. Try all options and you might get some important documents back.
Ransomware spreads through infected email attachments
As we already mentioned, this virus spreads through the infected email attachments, so you have to be careful when opening newly received emails. Especially, look out for emails from unknown senders, possibly containing some spelling mistakes or other unusual features. If you have accidentally downloaded this malicious virus, you must remove it ASAP.
However, it is rather difficult to notice it infiltrating the system. You may notice minor changes in the computer’s speed, but apart from that, the virus makes sure that the encryption process remains stealthy. The only way to really ensure the safety of your files is to keep a backup of your files and store them in some external storage.
However, we must warn you not to connect your external storage drives to the computer until you take care of the complete ransomware removal from the system because this virus may also be capable of infiltrating and locking the files on these platforms as well. So, the key methods to keep your files safe is to be careful with new suspicious emails and keeping backups of your files.

How to prevent from getting ransomware
Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
