Bluesky is a virus that targets the files of its victims with the goal of locking them via encryption. The Bluesky lockdown on the affected files keeps the data inaccessible until the victim transfers a certain amount of ransom money to the hackers.

The category of viruses (Llqq, Lloo) known for doing this is known as Ransomware and is currently one of the most widespread forms of malware. The specific thing about Ransomware is that it doesn’t really damage the computer it infects. Ransomware cannot corrupt the OS, tamper with its settings, or make any other unwanted changes. Furthermore, the files that it encrypts don’t actually get damaged by the virus – they are supposed to stay intact so that the blackmailers have leverage upon which they can demand the ransom payment. Instead of corrupting or damaging the targeted files, Bluesky simply places encryption on them which locks the files and keeps them totally inaccessible regardless of what program the victim might try to use in order to open their data.

The Bluesky virus

The Bluesky virus is a software threat of the Ransomware category and it can encrypt all important data located on your computer. The Bluesky virus is used as a blackmailing tool and, once it locks the files, it will ask you to pay the ransom.

Many users either do not have the needed money or can’t afford to spend such a sizable sum (we are talking four-digit numbers) on releasing their data from hackers. But what if you have the money readily available and can afford the payment? Should you then send the money in order to free your files if the locked files are really that important to you?

There can be no single universal answer here, but the general rule is to refrain from going for the payment “option” right away and to instead try all other potential solutions that might be available. The problem with the payment, aside from the need to part with a significant amount of money, is that there is no real guarantee that the files would be returned to you even after you execute the payment. Remember, the people behind Bluesky are criminals and trusting them is probably not a very wise thing to do. Therefore, our advice for those of you who desperately need to get their files back because this Ransomware has locked them is to follow the removal guide from this page and then give a try to the recovery suggestions that are shown after the removal steps in a separate section.

The .Bluesky file extension

The .Bluesky file extension is a sequence of characters that the virus adds to the names of your files during the encryption process. Since the .Bluesky file encryption doesn’t represent a real data format, the software on your computer cannot recognize it.

Decryption is usually the method that can take care of this extension problem but since paying to get your files decrypted might not really be a good idea, we suggest that you first try the alternative methods from our guide and see if any of them help you.

    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:

    hosts_opt (1)


    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.

    • Please 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 EnterOnce 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:

    1. %AppData%
    2. %LocalAppData%
    3. %ProgramData%
    4. %WinDir%
    5. %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!
