Zzzzz virus Removal Guide
What is Zzzzz ransomware virus?
Zzzzz ransomware – yet another Locky version
Despite the amusing title, Zzzzz virus is no joke at all. It signals that your computer has been infected with the version of notorious Locky virus. Those, who might not have heard about this notorious ransomware, take a look at this article . The malware has gained such title for its feature to encode all your personal files and append .zzzzz extension. However, dealing with this does not leave any positive experiences for its victims. Even if you happen to be on the list of targeted users, there is no need to panic. The first thing you should do is remove Zzzzz completely from the device. In that case, do not waste time and entrust the process to a reliable security tool, such as ReimageIntego. After then, focus on data recovery options.
After Locky had dashed through the Internet with an immense force a couple of months ago, some virus researchers voiced their hopes that the cyber terror was finally over. However, little did they know what Locky developers had up their sleeves. The ransomware has been revived again. As a result, we have seen major new updates: ODIN, Thor, .shit file extension, and .aesir virus hit the Internet. What is more, the hackers even decided to aim higher as they infiltrated Facebook and spread the malware there . The ransomware payload was hidden in a .svg file. Though it is unknown which version has been distributed, there are speculations that millions of the virus versions were dispersed. As the week hasn’t passed since the previous version, .aesir file virus appeared, Zzzzz malware made its appearance. Its operation way has not altered as it encodes the data with RSA-2048 and AES-256 algorithms. The main advantage of this method is that it utilizes the combination of mathematically interrelated public and private key . Consequently, the process of decrypting the files without the private key remains a tiresome task.
Researcher shows ransom notes left by Zzzzz ransomware virus. Once it encrypts victim's files, it adds .zzzzz file extensions to them.
On the one hand, it is practical that you can see which files are affected as they are now altered into the files with [8_random_characters]-[4_random_characters]-[4_random_characters]-[4_random_characters]-[12_random_characters].zzzzz file extensions. More explicit information on how to recover the files is provided in instruction.html file. Taking into account that Zzzzz ransomware is the version of infamous Locky, it is futile nurturing hopes of file recovery. Their offered Locky Decrypter might cause more damage rather than bring benefit. Paying 731.52 USD (1 BTC) for it may turn out into a futile activity after all. Focus on Zzzzz removal procedure rather than on the financial transaction.
Zzzzz file extension relates to two different viruses
Although Locky ransomware creators were the first ones to use .Zzzzz file extension, it seems that they have inspired developers of Dharma ransomware to create a similar virus that uses the same extension. However, it must be said that Dharma Zzzzz ransomware acts differently and for some, its developers released not so many versions of it. The most significant difference between Locky's Zzzzz virus and Dharma's variant is that the latter one appends an email address to the encrypted file name, for example, .[email@example.com].zzzzz. This email was spotted in .wallet file extension versions of Dharma, which appeared before these Zzzzz ransomware variants. However, although Locky and Dharma used to append similar extensions to encrypted files, these viruses are entirely different. No one managed to defeat not a single version of Locky, whereas Dharma ransomware project seems to be falling apart step by step. Someone (probably from the ransomware development team) has released a bunch of decryption keys; however, they appear to be working with certain variants of Dharma only. Nonetheless, we suggest trying this decryption tool by Kaspersky to restore your files if you find .[email].zzzzz file extensions on them.
How does ransomware find a way to infect a computer?
It is not difficult for ransomware threats to occupy the devices of those users who carelessly review their spam folders. Recently, some versions of Zzzzz hijack were detected in fake Amazon emails. The crooks disguise the malware in the email which is supposedly sent from this respective company asking to review the content of the attached file. What is more, the racketeers even dared to exploit the image of the Office of Personnel Management (OPM) to convince users into opening the files . Luckily, in both cases, it is not difficult to suspect the fraud as the counterfeited emails contain several grammar mistakes, type and style errors. Locky still remains to be one of the most destructive ransomware threats. Its authors publish a new version every week. Therefore, beware of the latest edition – Osiris ransomware. All in all, having un-updated malware removal utility is a must as well .

How to prevent from getting ransomware
Protect your privacy – employ a VPN
There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals.
No backups? No problem. Use a data recovery tool
If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.
If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
