ransomware (Free Instructions) - Decryption Steps Included virus Removal Guide

What is ransomware? ransomware is a cryptovirus that mimics an infamous Gandcrab with its .crab file extension ransomware ransomware is a cryptovirus that locks data to demand ransom from the victim. ransomware is a dangerous cryptovirus that encrypts users' data and marks it with either .crab or .qweuirtksd file extensions. However, the cyber threat does not belong to an infamous GandCrab ransomware family but belongs to another big family called Scarab and can be called one of the versions of Qweuirtksd ransomware. The main aim of this malware is to trick its victims into paying the ransom. For that, it encrypts files with the help of sophisticated encryption algorithm and additionally declares that the only way to recover them is the ransom. However, if you happen to find .[].crab file extension appended to your files this about backups. Also, security experts[1] note that you can try to recover encrypted special data recovery software.

This ransom virus first was spotted on the first time during the first week of October. While it is obvious that the malware is hailing from Scarab family, it seems that ransomware can also be yet another version of Qweuirtks virus. However, the biggest difference is in the ransom note that cyber threat generates and places on the system after data locking. ransomware generates the ransom message called HOW TO RECOVER ENCRYPTER FILES.txt which includes just a couple of facts about contacting the developers and nothing more. Here is the full text is displayed in a ransom note:

Your files are now encrypted!

Your personal identifier: ***

Unfortunately, data encrypted by ransomware becomes inaccessible and useless. As many ransomware[2] developers state in their ransom messages that paying the ransom is allegedly the only solution. Without a decryption tool, your data cannot be decrypted, but you can try data recovery tools or replace encoded files with safe ones from the external backup.

You need to remove ransomware from the system and then attempt to restore your data. Paying the ransom gets you nowhere, and it may lead to permanent data or money loss. Contacting cybercriminals is a bad idea, and you shouldn't do that in any case.

Proceed with ransomware removal and clean the system before you restore your data because ransomware can encrypt your date again and affect newly added files, if not terminated completely. Follow our instructions below and use a reputable anti-malware like FortectIntego to clean your system. ransomware is a cyber threat that comes to your system without any permission and changes the state of your photos, videos, documents, and archives.

Ransomware can be distributed with the help of other malware

Cyber threats like trojans, worms, and malware can be set to do a variety of things once infiltrated. Spreading ransomware can be one of many functionalities. However, direct ransomware payload or malware designed to spread infections, all come from insecure file attachments in emails.

Spam email campaigns often distribute malicious components and can look very legitimate or safe. Email box has a section for spam email box, but malicious emails may appear on the regular email box and lure you into downloading and opening infected files. Pay attention to details if you got an email that looks suspicious:

  • infected email may be written in bad English, contain various typos or grammar mistakes;
  • subject line appears to be “financial information” or something in that manner;
  • sender appears to be a well-known company like FedEx or PayPal[3].

Researchers note that any Word file attached to a questionable email can be infected with macros and install the ransomware on your device once you download and open the document on your system. You can try scanning the device with antivirus tool before opening. Make sure that you pay more attention to emails you get.

Eliminate all files possibly related to ransomware

If you need to perform ransomware removal, make sure to use tools designed for this process and do that immediately after noticing any activity. The best thing you can do, in this case, is employing your reliable antivirus or downloading and installing an anti-malware tool like FortectIntego, SpyHunter 5Combo Cleaner or Malwarebytes.

To remove ransomware manually you would need to have better skills in IT, so we recommend using automatic virus termination method. A full system scan with anti-malware tools also improves the performance of your PC when it cleans additional files or programs off of the system.

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
