GandCrab virus Removal Guide
Description of GandCrab virus
Criminals aim to infiltrate GandCrab ransomware on as many computers as possible
GandCrab is a ransomware-type infection which targets to encrypt data on the computer and as for a ransom in exchange for a decryptor. Developers employ two exploit kits and deceptive PDF file attachments to infiltrate the virus on the machines. Files become unusable as soon as they are appended with .GDCB extension and victims receive GDCB-DECRYPT.txt file as a ransom note.
Those whose computers are infected with GandCrab are demanded to pay 1.54 DASH which is an open source cryptocurrency. According to the experts, it particularly aims to compromise 64-bit versions of Windows operating systems. Here is the fraction of the ransom note:

3. Open Tor Browser
4. Open link in tor browser: http://gdcbghvjyqy7jclk.onion/[id]
5. Follow the instructions on this page
On our page you will see instructions on payment and get the opportunity to decrypt 1 file for free.
Do not try to modify files or use your own private key – this will result in the loss of your data forever!
Criminals inform their victims about the data encryption and claim that the only way to get back the access to the files is to purchase a private key. At the current exchange rate, its cost is approximately $970. Also, to earn people’s trust developers of GandCrab ransomware offer to decrypt one file for free.
Although, we can assure you that there are alternative ways how you can recover compromised documents without paying the ransom. First, you need to remove GandCrab to be able to start data recovery. You can find the guide below which will help you with the procedure.
GandCrab ransomware is a file-encrypting virus which spreads with the help of Rig and GrandSoft exploit kits.
Additionally, GandCrab virus is designed to have a timer — one the given time runs out, the amount of the ransom doubles. This is another great reason why you should NOT trust the criminals. They are unreliable and may trick you into making the transaction without giving the decryption key.
Therefore, we strongly advise you to consider GandCrab removal as soon as it reaches your system. You can get rid of it quickly with the help of ReimageIntego or another robust antivirus. Remember, you have alternative ways how to recover encrypted files without suffering from financial losses.
The peculiarities of Rig and GrandSoft exploit kits which are said to be the primary ransomware attack vectors
Cybersecurity experts have detected the primary source which helps to infiltrate the ransomware on the targeted computers — RIG exploit kit and GrandSoft exploit kit. This software is designed to find system vulnerabilities and utilize them to let the malware inside. Currently, developers of this file-encrypting virus are actively spreading their program via the malspam campaign, called Seamless.
While criminals send spam letters to random people, they all contain a fake PDF attachment which is set to download the .doc file and run a PowerShell script. The bogus code creates sct5.txt file which executes an exploit and points the direct way for malware to infiltrate the system.
Experts warn that spam emails have Receipt Feb-21310 [random numbered] subject and are sent from the email address which contains [different text]@cdkconstruction.org end. Likewise, if you receive an email with information mentioned above, immediately delete it and do NOT open the attachment.
It is worth to mention that you can quickly spot a spam email with malicious intentions by carefully checking for spelling mistakes or encouragements to click on the file attachment. Usually, crooks impersonate legitimate companies and try to lure gullible people into opening a fake invoice for further details.
Be careful and is you see a suspicious email, do NOT click on it. Especially be cautious of file attachments with the following extensions:
Additionally, be careful when downloading software from suspicious websites. Hackers might trick you into downloading malware which disguises as legitimate programs. Therefore, the best decision would be to get a robust malware removal tool and download applications only from authorised developers.

How to prevent from getting ransomware
A proper web browser and VPN tool can guarantee better safety
As online spying becomes an increasing problem, people are becoming more interested in how to protect their privacy. One way to increase your online security is to choose the most secure and private web browser. But if you want complete anonymity and security when surfing the web, you need Private Internet Access VPN service. This tool successfully reroutes traffic across different servers, so your IP address and location remain protected. It is also important that this tool is based on a strict no-log policy, so no data is collected and cannot be leaked or made available to first or third parties. If you want to feel safe on the internet, a combination of a secure web browser and a Private Internet Access VPN will help you.
Reduce the threat of viruses by backing up your data
Due to their own careless behavior, computer users can suffer various losses caused by cyber infections. Viruses can affect the functionality of the software or directly corrupt data on your system by encrypting it. These problems can disrupt the system and cause you to lose personal data permanently. There is no such threat if you have the latest backups, as you can easily recover lost data and get back to work.
It is recommended to update the backups in parallel each time the system is modified. This way, you will be able to access the latest saved data after an unexpected virus attack or system failure. By having the latest copies of important documents and projects, you will avoid serious inconveniences. File backups are especially useful if malware attacks your system unexpectedly. We recommend using the Data Recovery Pro program to restore the system.
