Corona-lock Corona-lock is a ransomware cryptovirus that is used for online blackmail purposes and money extortion. Corona-lock uses advanced cryptography to restrict access to certain files and demands a ransom payment to send the victims a decryption key. In general, Ransomware is incredibly common extortion software that can cause the loss of a lot of valuable digital files. Such infections seek to encrypt their victims' files and make them unavailable, so that hackers can subsequently blackmail users to pay ransoms to decrypt them. The strategy is very clear. The crooks promise that the victim will receive a unique decryption key to reverse the complex code applied to their files as soon as they pay the required money. At least this is what you're told by the hackers in a message which will be displayed on your screen by the virus the moment all your files have been successfully encrypted. Of course, if the encrypted files are not especially important for you, you should ignore the ransom-requesting message and simply remove the ransomware from your computer. The good news is that, aside from blocking access to stored information, ransomware-based viruses normally don\u2019t cause any permanent system damage that will prevent you from using your computer as before. That\u2019s why, as long as you successfully remove Corona-lock , you can start using your computer right away and safely connect any file-backup sources that you may have. However, if Corona-lock has already encrypted files that are of great importance to you but you don\u2019t have backups of them, you may have to face a very unpleasant dilemma that must be treated with care. Basically, you have to choose between either agreeing to pay the hackers behind the ransomware a ransom or looking for alternative methods for file recovery to minimize the attack's effects. The Corona-lock virus The Corona-lock virus is a malicious piece of software of the ransomware type that encrypts user files with advanced encryption algorithms. After applying its encryption, the Corona-lock virus asks for a ransom payment from its victims in order to provide them with a decryption key for their information. Many people get panicked when they face the scary ransom message that Corona-lock displays on their screen and are quick to agree to the ransom payment out of fear. However, security experts suggest that the victims or ransomware should take some time to learn about alternate ways to deal with this infection instead of immediately sending the demanded money to the hackers. This is mainly because there is absolutely no assurance that once they pay, the crooks will provide them with the mysterious decryption key. In fact, it is much more likely for them to disappear with the money. That\u2019s why it is best to leave this choice as your very last resort and firstly explore some other methods to potentially restore your files and remove the ransomware virus. The Corona-lock file encryption The Corona-lock file encryption is a process by which hackers can limit access to user data using a sophisticated encryption algorithm. The Corona-lock file encryption process does not destroy the targeted data but makes it unavailable without the application of a decryption key. The tips in our removal guide below, however, are published to help you get some of the encrypted information back without having a decryption key. To give them a try, however, don't forget to first remove Corona-lock , as everything you manage to restore while the malware is on your computer may get encrypted again. SUMMARY: Name Corona-lock Type Ransomware Danger Level High (Ransomware is by far the worst threat you can encounter) Symptoms Very few and unnoticeable ones before the ransom notification comes up. Distribution Method From fake ads and fake system requests to spam emails and contagious web pages. Data Recovery Tool Not Available Detection Tool Remove Corona-lock Ransomware Some of the steps will likely require you to exit the page. Bookmark it for later reference. Reboot in Safe Mode (use this guide if you don't know how to do it). WARNING! READ CAREFULLY BEFORE PROCEEDING! Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab. Try to determine which processes are dangerous. Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner: After you open their folder, end the processes that are infected, then delete their folders. Note: If you are sure something is part of the infection - delete it, even if the scanner doesn't flag it. No anti-virus program can detect all infections. Hold the Start Key and R - copy + paste the following and click OK: notepad %windir%\/system32\/Drivers\/etc\/hosts A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below: If there are suspicious IPs below "Localhost" - write to us in the comments. Type msconfig in the search field and hit enter. A window will pop-up: Go in Startup ---> Uncheck entries that have "Unknown" as Manufacturer. \tPlease note that ransomware may even include a fake Manufacturer name to its process. Make sure you check out every process here is legitimate. Type Regedit in the windows search field and press Enter. Once inside, press CTRL and F together and type the virus's Name. Search for the ransomware in your registries and delete the entries. Be extremely careful - you can damage your system if you delete entries not related to the ransomware. Type each of the following in the Windows Search Field: \t%AppData% \t%LocalAppData% \t%ProgramData% \t%WinDir% \t%Temp% Delete everything in Temp. The rest just check out for anything recently added. Remember to leave us a comment if you run into any trouble!
