Gefest virus Removal Guide
What is Gefest ransomware?
Gefest 3.0 ransomware is data locking malware that was created by Scarab virus authors
Gefest virus - ransomware which uses RSA encryption to lock up data
Gefest ransomware, also known as Gefest 3.0 ransomware, is another file encrypting infection that belongs to one of the most prominent malware strains of such kind – Scarab. The virus uses the RSA-2048 algorithm[1] to lock up all documents, pictures, videos, databases and other data that is stored on the infected device. All files are then marked with .GEFEST and the ransomware generates a text file HOW TO RECOVER ENCRYPTED FILES.txt in which crooks are urging their victims to pay a ransom in exchange for the decryption key.[2]
Just as it typical to crypto-lockers, Gefest virus authors demand ransom to be paid in Bitcoins or other cryptocurrencies, although the precise amount is not mentioned in the note. Prior to that, victims are asked to contact hackers via mrpeterson@cock.li or debora2019@airmail.cc emails -an action which is not recommended by most security experts and law enforcement.
After its initial release, Scarab-Gefest is still active, with recently releasing such versions as .Gefest3 [Mrpeterson@cock.li].GFS, and .crabslkt.

Once inside the system, Gefest ransomware performs a variety of changes to the computer system. Ransomware viruses, including this one, might alter the registry, drop its own files, and even disable your anti-virus software. Additionally, most of the cryptolockers are programmed to delete Shadow Volume Copies,[3] consequently complicating the recovery process.
To prevent Gefest 3.0 and similar ransomware infections, make sure you are very careful while dealing with emails from unknown senders. More about the prevention of ransomware can be found in the second part of this guide.
After encrypting files, Gefest 3.0 ransomware provides this type of message (might vary, depending on the extension):
GEFEST 3.0 ransomware

As we already mentioned, the Gefest decryptor price is withheld on the note, and usually depends on how quick victims contact cybercriminals, and sometimes even their financial status. Additionally, hackers offer a test decryption service, which is meant to prompt users to deem them more reliable.
Gefest ransomware is a computer virus which is related to Scarab
Nevertheless, no matter how much Gefest ransomware authors may want to seem genuine, never trust these people: they already locked your files without asking, what makes you believe they will send you the decryptor after the payment?
In such a case, you might lose not only your files but also money. Therefore, remove Gefest ransomware from the system instead as a first step by using a reliable anti-virus program. After that, you can use FortectIntego to detect all malware-laden components on your computer and fix the infected system files.
After you deal with the Gefest 3.0 ransomware removal, you can start thinking about possible data recovery methods. Even though no decryptor has been released yet, you can contact Emmanuel_ADC-Soft on Twitter for possible decryption solutions. Alternatively, you can employ third-party data recovery software – we provide all the download links and operation instructions below.
File-encrypting viruses can infect computers after opening a malicious attachment or clicking a link in a spam email
According to computer experts from NoVirus.uk,[4] if you have caught a ransomware[5] infection recently, there might be more than one way how this cyber threat has invaded the system. However, the most popular ransomware distribution technique is email spam and infected attachments that come clipped to these questionable-looking messages.
Opening the attached files or entering the inserted link might cause you a lot of problems. This way you might easily execute the virus-related content and inject ransomware straight into the system unknowingly. Always be careful while opening your inbox, identify the sender, check for grammar mistakes, evaluate the risk, and just then decide.
Moreover, you should avoid various Internet sites which might lack protection and seem unsafe. Do not click on any suspicious links that might secretly install unpleasant apps or malware. Additionally, we recommend downloading a reputable computer security tool to secure the system fully. Also, you will be able to perform regular system scans with the automatical software and find out if there are any troubles in the system.
Gefest ransomware can append a variety of extensions, including .GEFEST, .Gefest3, .GFS, and .crabslkt
Make Gefest 3.0 ransomware vanish from your device and systems
To remove Gefest 3.0 virus, you will need to download and install reliable antimalware. Do not try opting for manual removal as you can easily delete useful system components. To detect all malicious files, use a reputable program such as FortectIntego or SpyHunter 5Combo Cleaner. Remember, you need to disable the malicious activity before you carry out any data recovery steps because the virus can attack your files right after rebooting the system.
After the Gefest ransomware removal is completed, you can try restoring your entire computer system. For that, proceed with file recovery techniques displayed below this article. Note that the easiest way to recover encrypted files is to use backups. However, if you don't have such, there are still better options than contacting the crooks and facing unwanted money loss.
To avoid getting infected with a virus such as Gefest 3.0 ransomware in the future, make sure you are careful with emails from unknown senders, illegal software and questionable links. Moreover, you need to take care of your files and valuable data properly: store all important files in a USB Flash Drive[6] or on an iCloud server. This way the data will be kept out of reach from anyone else except you.

How to prevent from getting ransomware
Do not let government spy on you
The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet.
You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.
Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.
Backup files for the later use, in case of the malware attack
Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.
When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
