Paaa
Paaa is a cryptovirus infection based on Ransomware code. The purpose of Paaa is to sneak inside a computer without being detected and encrypt the files stored there in order to demand a ransom for their decryption.It is of utmost importance to remove the Ransomware infection if you want to be able to use the infected computer normally and bring it back under your command. Therefore, on this page, we will share our tested and comprehensive measures with the help of which to completely remove Paaa from your system. You are also likely interested in learning how to get your data back and that’s why the guide below will take you through a file-recovery process that can potentially help you get back some of your most needed digital documents.
The Paaa virus
The Paaa virus is a Ransomware threat capable of taking hostage your digital information that’s stored on the computer. The Paaa virus does that by secretly encrypting the most valuable user files and demanding a ransom for their decryption.The Ransomware does not corrupt your system or perform malicious activities that other viruses do, such as spying, collecting data, or deleting files. Instead, it uses a strong encryption algorithm that converts the information stored on the infected device into an unreadable string of symbols that can’t be recognized by any software. In this way, the infection renders all coded documents unreadable and prevents the users from accessing them.
Normally, the contamination with Ransomware happens when users interact with harmful online content or download and install infected software. Possible carriers of threats like Paaa,Veza, Vehu and Vepi could be spam emails, attachments to random messages, infected links, torrents, and sites with low reputation. Generally, the moment of the infection and the entire file-encryption process go unnoticed until the Ransomware shows itself on the victim’s computer with a ransom note.
The Paaa file decryption
The Paaa file decryption is a process that is supposed to bring all encrypted files back to their previous state. To activate the Paaa file decryption process, the victims need to purchase a decryption key from the hackers behind the Ransomware.Direct decryption of the Paaa files is only possible after the application of a special decryption key. Sadly, the crooks who control the Paaa infection will keep this key in secret and would only exchange it for a money transfer payable in Bitcoins. Very often the attackers threaten to destroy the decryption key unless the payment is made on time. They may also threaten to double the ransom to get the victims to pay more quickly. You should realize, though, that these are deceptive methods used by cyber criminals to make their targets act impulsively. Besides, the cyber criminals don’t really care about your documents and there’s nothing that can make them give you the key they promised once they receive the payment.
Therefore, most security experts will warn you not to pay a cent to these crooks. Instead, many professionals, including our “How to remove” team, will encourage the attacked victims to remove the Ransomware and to try to recover their data from backups whenever that is possible. These could be personal backups (on an external drive or a cloud) or system backups that could be extracted from the system. More details can be found in the removal guide below, so follow the steps closely and let us know if they have been helpful.
SUMMARY:
*Paaa is a variant of Stop/DJVU. Source of claim SH can remove it.
Remove Paaa Ransomware
Next, since Paaa may run a number of malicious processes as a background, it is best if you run only the most essential system processes and apps in order to be able to easily spot the malicious ones. For this, we advise you to reboot the infected PC in Safe Mode (use the free instructions from the link) and then get back to this removal guide by clicking on its bookmark.
WARNING! READ CAREFULLY BEFORE PROCEEDING!

With the infected computer launched in Safe Mode, click on the Start menu button and type msconfig in the search bar. Then open the result and a System Configuration window will open:
If you detect anything suspicious, research it online and, based on the information you collect, decide whether you need to disable it.
To disable a suspicious startup entry, remove its checkmark from the related checkbox and click OK.
Next, head to the Windows Task Manager (CTRL + SHIFT + ESC) and select the Processes Tab. Similarly to what you did in the Startup tab, search the list of processes for suspicious entries. Keep in mind that Paaa may hide its malicious processes under different names that may mimic the names of legitimate processes. If you detect an entry that looks suspicious, (uses a lot of CPU and Memory without any particular reason, has an odd name, etc.) here is how to check it:
- right-click on the process in question
- select Open File Location
- end the processes in question if one or more of its files get flagged as dangerous.
A typical location where a ransomware like Paaa may make unauthorized changes is the Hosts file of the infected computer. To check it, you need to copy the line below in the Start menu search bar and press Enter:
notepad %windir%/system32/Drivers/etc/hosts
The Hosts file will open in Notepad.
Search for Localhost in the text, and if you find it, check if any virus creator IP addresses have been added there. The image below can give you an idea of how should those IPs look like.
If you detect nothing suspicious in your Hosts file, just close it down. If something disturbing catches your attention, though, don’t rush to delete it. Better write to us in the comments with a copy of what is bothering you.

In case of a ransomware infection, you may need to clean the Registry from malicious entries that the virus has added there. To do that, type Regedit in the Start menu search bar and press Enter.
This will launch the Registry Editor on your screen. Next, press CTRL and F together and type the Name of the virus that has infected you and start a search. If any entries show up in the results, they most likely are linked to the ransomware and need to be removed from the Registry.
NB!!! A serious system damage may occur if you delete entries nor elated to the ransomware from your registry. To avoid the risk of OS corruption, please use a professional removal tool to clean your registry from malicious files.
Next, close the Registry Editor once you are sure the Registry is clean from malicious entries and click on the Start menu button. In the search field, type each of the lines below one by one and open the result:
- %AppData%
- %LocalAppData%
- %ProgramData%
- %WinDir%
- %Temp%
In case you detect entries with odd names consisting random characters, or entries that have been added close to the time you got infected with Paaa , they most likely need to be removed.
You also need to remove all the files in the Temp folder, as these are temporary files that could be related to the ransomware.
How to Decrypt Paaa files
Once your computer is clean from Paaa and you are sure that there are no ransomware traces in it, you can check our comprehensive guide with file-recovery suggestions that can be found here.
New Djvu Ransomware
The latest Djvu ransomware variant, known as STOP Djvu, is easily identifiable thanks to the .Paaa extension appended to the victims’ encrypted files. As of this writing, it is possible to decode files encrypted with this version if they were encrypted with an offline key. If you need assistance decrypting files, try the application at the following link:
https://www.emsisoft.com/ransomware-decryption-tools/stop-djvu
If you click the Download button at the top of the page, you’ll be able to save the STOPDjvu.exe decryptor on your computer. Right-click on the file, and select “Run as Administrator” to launch the decryptor. Decrypting your data should start as soon as you’ve read the license agreement and completed the brief setup process. Keep in mind that if a file was encrypted using an unknown offline key or if it was encrypted online, this tool may not be able to decode it.
However, before attempting any data recovery methods, you should check that the ransomware has been completely eradicated. It is recommended that you scan your computer with a specialized anti-virus software, such as the one we offer here on our site. You can also check individual files with the free online virus scanner.
