Rastar virus Removal Guide
What is Rastar ransomware?
Rastar ransomware – a file-locking parasite that gives its victims 24 hours to pay the ransom or all files get permanently deleted
Rastar ransomware - the virus that makes changes to your files, so the ransom is demanded.
Rastar ransomware is a cryptovirus that urges its victims to pay the ransom in cryptocurrency Bitcoin within 24 hours of the attack, or the encrypted files on the infected computer will be lost permanently. This file-locking virus was first detected by the xiaopao.
When ransomware, such as Rastar ransomware virus, accesses a computer system, it immediately starts the encryption process. All personal files such as databases, archives, documents, pictures, etc., are renamed by appending a .rastar extension to all of them, making them inaccessible.
Afterward, ransom note text files named HOW_TO_DECYPHER_FILES.txt are created and placed in every folder with locked files. The purpose of these notes is to intimidate .rastar file virus victims into contacting the criminals (email@example.com) and meeting their demands.
|Appended file extension||Personal files are renamed by adding .rastar extension|
|Criminal contact details||One email is provided to establish contact – firstname.lastname@example.org|
|Additional info||Cybercriminals state that the victims have 12 hours to pay the ransom, or the price will be increased. If the victims don't contact the assailants within 24 hours, they claim that the encrypted files would be deleted permanently|
|Virus removal||Use professional anti-malware software to remove Rastar ransomware|
|system repair||Use the ReimageIntego tool to fix any damage the cryptovirus might have caused to system files and settings|
In the ransom note of Rastar ransomware, the cybercriminals start by explaining what happened to the victim files and that the only way to recover them is to pay an unspecified amount of Bitcoins. If that's not done within 12 hours of the cyberattack, the indefinite ransom sum will be increased.
Furthermore, developers of this file-locking parasite claim that if the victims don't establish contact and meet their demands within 24 hours, all their files on the infected devices will be permanently deleted. Here's the whole message from the ransom note:

Although it might seem like a good idea to contact the creators of Rastar ransomware and pay the ransom to end this nightmare, it's actually the worse thing any victim of a cybercriminals attack can do, and here are a few reasons why:
- The assailants might disappear as soon as the money is forwarded to them
- There's no guarantee that the promised decryptor will ever be delivered or that it will work
- The ransom funds could be used to attack more innocent people
- The same money could be used to finance research of more effective ransomware and attack methods.
Having said that, we recommend users to remove Rastar ransomware from their affected devices with the help of professional anti-malware software like Malwarebytes or SpyHunter 5Combo Cleaner, which will not only automatically locate, isolate, and delete it but might protect them from such incidents in the future.

Dodge ransomware that's hiding on file-sharing platforms
Cybercriminals have many techniques at their disposal when talking about ransomware distribution, from phishing emails to remote desktop protocol (RDP) attacks. Still, our research shows that one of the most frequently used methods to spread this type of malware is through file-sharing platforms.
These platforms, including torrent websites like The Pirate Bay, BitTorrent, and others, might be crawling with different malware kinds, including ransomware, because no one, except for the end-user, inspects what uploaded to them.
Cybercriminals exploit this by disguising their creations as unlocked licensed software, illegal activation toolkits (aka cracks) for the latest games, or anything else that would stick out and draw the attention of a soon to be victim. Please refrain from using these types of file-sharing platforms for your own safety.

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.
Recover files after data-affecting malware attacks
While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.
Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
