The Aayu virus is a ransomware infection specialized in file encryption. The creators of the Aayu virus blackmail the infected users to pay a ransom in exchange for a decryption key for their encrypted files.

Aayu is usually spread through fraudulent publications, spam messages, emails with infected attachments, numerous fake advertisements, bogus deals, infected web links and intriguing pop-ups. Many ransomware infections also use Trojans to sneak inside the computer without being identified. Sometimes, all that is required to get infected with a virus like Aayu , Aamv or Eemv is one wrong or accidental click on an infected link or a web messages and your files will be encrypted for good before you realize it.

The victims mostly come to know about the consequences after a ransom-demanding message gets displayed on their screen. The message typically contains specific payment instructions and a deadline, after which the required amount of money is normally increased or the decryption key is not available anymore in return for the payment. Unfortunately, there is no assurance that you can get a decryption key from the hackers, regardless of whether or not you pay the required ransom.

This suffix cannot be recognized by any application, meaning that the Aayu file is inaccessible.

The second step is to access the Task Manager on the infected computer by simultaneously hitting Ctrl, Shift, and ESC. To see the running processes, click the Processes tab at the top of the window. Search for any questionable-looking processes with odd names by sorting them by memory and CPU use.


If you see a process that appear suspicious, right-click on it and choose “Open file location” to see the files related to it. Scan those files with the powerful scanner below to see whether they are infected with malware.

    Malicious software may also store some of its files in the computer’s registry in order to keep them there for as long as possible. So, you’ll need to carefully search the Registry Editor for entries related to Aayu and remove them one by one. To open the Registry Editor, simply enter regedit in the Windows search field and hit Enter.

    Once the Editor opens, press Control and F together and open a Find window that allows you to quickly search for malicious files. To search for files related to Aayu, enter the name of the threat in the Find box and click on the Find Next button.

    Attention! Non-experts may find it challenging to remove entries associated with ransomware from the registry. What makes things even harder is that, any wrong deletions in the registry may lead to serious system and software corruption. That’s why, if you suspect that Aayu-related files are hiding in the registry, we recommend that you use the malware removal application available on our site. Once it removes the dangerous files, the software may also be used to prevent future virus intrusions into the system.

    Aside from the registry, you should look in the following five system locations and manually search them for recently added files and folders that look suspicious. Press Enter after entering each of the search terms below in the Windows Search field to open them: 

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

    Thoroughly inspect the files in each directory, but remove them only if you are certain they are part of the threat. The Temp folder’s files may be safely removed by selecting them and hitting the Del key.



    How to Decrypt Aayu files

    Ransomware infections are tough to deal with, and the major reason for that is their complex file encryption. Oftentimes, even if you successfully remove the threat, your encrypted data does not get restored to its pre-attack state. Furthermore, the decryption methods for various ransomware strains may vary greatly from one another. Our first piece of advice, if you’re determined to try everything in your power to restore your data, is to check the appended file extensions of the encrypted files. This will help you to identify the exact ransomware variant you’re up against, and then search for the best file-recovery solutions that are available.

    Before starting with any data recovery, though, a thorough malware scan should be performed on the infected computer using a specialized antivirus application, such as the one available on our website. Only after making sure there isn’t a virus on the system, you may start to look into file restoration methods.

    New Djvu Ransomware

    STOP Djvu is a new ransomware variant that has been actively attacking users all over the world and taking their data hostage by applying a complex encryption to it. Victims have reported that files encrypted with this new version have the .Aayu extension. However, despite the fact that this is a new and very active threat, those who have been attacked shouldn’t give in to the ransom demands. In the link below, there is a decryptor that may be used to recover encrypted files.


    Before beginning the decryption procedure, please download the STOPDjvu executable file from the aforementioned website and familiarize yourself with the license agreement and accompanying instructions. Keep in mind that files that were encrypted using unknown offline keys or online encryption methods may not be decrypted with this program, but you still have a high chance of recovering your data if a known offline key was used to encrypt it.

    If you need more professional assistance to deal with Aayu and the instructions in this manual removal guide are not enough, you may wish to use powerful anti-virus software or a free online virus scanner.
