Chech Ransomware Removal Guide
What is Chech Ransomware?
Chech ransomware is a STOP virus variant that locks data then tries to blackmail users into paying ransom in digital currency
Chech ransomware is a file locking malware that demands $980 for locked personal documents, pictures, videos, and other data
Chech file virus is malware that belongs ransomware-type category and was first spotted by security researchers in late March 2019. It belongs to STOP virus family and uses a sophisticated AES encryption cipher to modify files that are most commonly used, such as .jpg, .doc, .pdf, .mkv, .xtml, .txt, and many others. The altered structure can also be noticed by an extension .chech – it will also prevent users from opening any of the personal data. Once done with the encoding process, Chech ransomware will contact a remote C&C server and drop a ransom note _readme.txt (other subgroups also use this file, including Promos, Kroput, Blower, etc.), which asks users to contact crooks via email@example.com or firstname.lastname@example.org and then pay $980 in Bitcoin for the file decryptor. While this variant is not decryptable, experts do not recommend paying bad actors and instead focus on Chech ransomware removal and alternative file recovery methods.
|Contactemail@example.com or firstname.lastname@example.org|
|Decryptable?||No. Use alternative file recovery methods|
|Removal||Use ant-malware software that can detect the threat|
|Recovery||To recover from virus damage, scan your device with ReimageIntego|
While there are multiple different infiltration methods that hackers use to propagate Chech file virus, it is most likely that users get infected with the threat after downloading and installing pirated software or its cracks. Additionally, opening and extracting attached files or clicking on links inside a phishing email is not a good idea either. Check our second section of the article if you want to know ways to protect yourself from Chech ransomware and similar threats.
As soon as Chech virus enters the computer, it performs a variety of changes to Windows system configuration, such as deletion of Shadow Volume Copies, establishing new scheduled tasks, modifying the registry, etc. The encryption process changes files as follows: a picture.jpg is turned into picture.jpg.chech.
As soon as Chech ransomware finishes the encryption, it drops a ransom note that states the following:

Chech ransomware is crypto-malware that infects users via cracked or repacked software installers
Therefore, we highly recommend users to remove Chech virus instead and never contact the crooks. This can be accomplished with reputable security software, although you might have to enter Safe Mode with networking for that. After you complete the Chech ransomware termination procedure, make sure you scan your PC with ReimageIntego – it will get rid of the virus damage and restore Windows registry, although it will not decrypt files. For that, you need to use specific software – you can find download links and usage instructions in our removal section below.
Be aware that some STOP ransomware variants (.promorad) was simultaneously distributed with AZORult malware – a Trojan that is capable of stealing user passwords, cookies, online banking information, and other sensitive details. Thus, if you got infected with Chech ransomware or any other variant, make sure you change your passwords and check your bank account to make sure no illegal transactions were performed.
Stay aware from pirated software and use automated tools that can stop ransomware viruses
As we already mentioned, malware authors often employ a variety of different methods for distribution. In STOP ransomware case, users are more likely to be infected while downloading pirated software or cracks/keygens from sites like Crackithub.com. In general, installing cracked software is illegal and might land you in jail in some cases. While you might get away with facing the consequences for copyright infringement, malware infections while visiting torrent and cracked software sites is highly likely.
Therefore, it is highly advisable staying away from high-risk sites. If you download anything, make sure you scan executables with tools like Virus Total or your anti-virus engine. Speaking of the latter, it is extremely important to keep anti-virus software installed on your device at all times. Additionally, you can also employ such tools like anti-exploit, real-time internet protection, ad-blocker, Firewall to maximize your protection.
You should not pay ransom and instead delete Chech file virus from your computer
It is best not to consider paying the ransom and instead focus on the Chech ransomware removal process. The initial infection might be incredibly overwhelming to users who never faced crypto viruses before, as, unlike most silent threats, ransomware makes sure that the victim knows about what happened (hence the ransom note, popping windows, wallpaper change, etc.). However, it is vital to stay calm.
Currently, there is no official decryptor available for Chech virus. Nevertheless, as practice had shown, security researchers are continually working on decryption tools for other STOP variants, and many of them are already decryptable. As for now, remove Chech ransomware from your machine with anti-malware software and attempt to recover data by using alternative methods – you can find all the instructions below.

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.

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.
