Pewcrypt virus Removal Guide
What is Pewcrypt ransomware?
Pewcrypt ransomware – a virus that is created to increase sub count for the famous YouTube star PewDiePie
Pewcrypt ransomware is a file locker that was created in order to make users subscribe to PewDiePie's YouTube channel
Pewcrypt ransomware is a file locking malware that is not created for money extortion purposes, unlike most of the other crypto-viruses are. The author, who is most likely a fan of a popular YouTuber PewDiePie, asks users to subscribe to his channel in order to surpass the sub count of the of Indian channel that uploads Bollywood movie trailers. Allegedly, the hacker claims that decryptor will be released as soon as the favorite YouTuber gets 100 million subscribers. Pewcrypt ransomware is written in Java programming language and uses AES-256 to encrypt data, and then RSA-2048 encryption for the key. Once the process is complete, all pictures, music, databases, documents and other data receives an extension .PewCrypt and becomes inaccessible for victims. Victims of malware are also introduced with a pop-up window which explains what happened to users' data and also displays T-Series and PewDiePie sub count. However, ransomware author, who goes by the name __JustMe__ on Twitter, has released the decryption tool for everybody to use for free.

Considering the immense popularity of this YouTuber (he has been the most subscribed blogger on the platform for over five years), it is not surprising that hackers are creating malware like Pewcrypt or PewDiePie ransomware. However, while in most cases cybercriminals use malicious actions to extort money from users, these viruses do not ask for that. Instead, they want victims to subscribe to PewDiePie.
Being a fan of somebody is OK, but corrupting users' personal files for the sake of the popularity of the YouTuber is purely malicious, and should still be treated negatively. We must give the author credit for releasing the decryptor for free, however. Nevertheless, you need to remove Pewcrypt ransomware before you can use the tool, as all the data will be encrypted repeatedly.
Once the Pewcrypt virus settles, it heavily modifies various Windows settings, spawns multiple processes, attempts to shut down security applications, writes to Windows registry, injects new processes, etc. This ensures that malware will be launched with every system startup.
As soon as file encryption is complete and .Pewcrypt extension is added to most of the files (note that malware skips files larger than 20MB, as well as .exe, .jar and .dll extensions) users can see a ransom note in a pop-up window, which states:
Your files have been encrypted using a 256 bit AES key which has been encrypted with a 2048 bit RSA key
In order to get your files back read the instructions bellow
– Subscribe to Pewdiepie (Hint: Hit the bro fist)
– Wait until Pewdiepie reaches 100 million subs at which point a decryption tool will be realseaed
If T-Series beats Pewdiepie THE PRIVATE KEY WILL BE DELETED AND YOU FILES GONE FOREVER!
It is up to you whether or not you want to subscribe to the channel, as it will not change to your personally. For the moment, you need to focus on Pewcrypt ransomware removal. In the early stages of the discovery, researchers warned that only 2 AV engines detected the threat. However, Virus Total results currently show that the malicious file is detected by 30 vendors under names like Trojan.GenericKD.41039316, Ransom_Agent.R002C0OBP19, PUA:Win32/Presenoker, Java/Filecoder.AF!tr., Win32:Trojan-gen, etc.
Once you eliminate Pewcrypt ransomware from your PC, make sure you scan it with ReimageIntego. It will be able to fix damaged Windows Registry and revert all the damage done to the operating system. Finally, you can use the decryptor released by the author to recover files, although backups and third-party tools are also available for PewCrypt ransomware decryption.
Pewcrypt ransomware is malware, written in Java, that locks ups data and does not demands ransom for file release. Fortunately, virus author released the decryptor (it should only be used after virus removal, however)

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.
