The Pouu Virus ransom note

Pouu is undoubtedly one of the most malicious variants of ransomware that could be encountered online. This malware is programmed to secretly encrypt your data and then display a ransom note on your screen asking for a certain amount of money. You can find more information about this awful program in the paragraphs that you are about to read but what you are probably most interested in is how to remove it and how to recover your encrypted files. That’s why, at the end of this article, we have published a free removal guide with ransomware-removal and file-recovery instructions that may possibly help you deal with Pouu.

The Pouu virus

The Pouu virus is malicious software created for blackmail purposes. The Pouu virus uses file encryption to restrict access to valuable user files and then demands a ransom payment from its victims in order to restore access to the encrypted files.

Pouu Ransomware is a really dangerous infection that can pose a challenge even for professionals in the field of cyber security. This being said, there is no guarantee that the encrypted data can be recovered unless the victims possess a full data backup copy.

This is how a standard Ransomware-based virus usually operates:

  1. The first step is to infect the device. This can happen in many ways but most commonly when users interact with a piece of web content that contains the ransomware infection. There may be many potential carriers of such malware that web users can come across: from program bundles and infected websites, fake ads, torrents, or spam email messages to shareware and malicious links. That’s why it really matters that you are careful when you browse the web and click only on reliable materials.
  2. After the ransomware enters your system, it will attempt to identify which files are most valuable to you and will encrypt them all with complex code.
  3. At the end of the attack, a ransom notification will be displayed on your screen. This notification will require a money transfer to a given cryptowallet in case that you want to regain access to the encrypted files.

The Pouu file encryption

The Pouu file encryption is a malicious process that the cyber criminals behind the Pouu ransomware use to prevent users from opening and using their information. The Pouu file encryption process runs in the background of the system and is typically not detected by most security programs.

The Ransomware-based Program’s (Zoqw, Poqw) intentions are clear – money extortion. However, you can never be sure about the intentions of the hackers who control it.

Don’t waste your money to sponsor criminals who target naive people. In case you don’t know where to start, our Removal Guide here can prove to be quite useful.

    In many ransomware attacks, dangerous files are added to your computer’s Registry in order to modify your system. No matter whether you’ve been infected with Pouu or any other virus, you should search the Registry for malicious entries and remove everything you think is linked to the infection. 

    To do that, simply type Regedit into the Windows search bar and press Enter to open the Registry Editor. Then, press CTRL and F together and type the ransomware’s name into the Editor’s Find dialog box. After that, click on the Find Next button in order to figure out whether there are any entries with that name and start a search. Anything that is found in the search results most likely should be deleted as it might be linked to the infection.

    Attention! An inexperienced user who doesn’t know which files are dangerous and need to be removed may do significant damage to the system if they make registry changes. Therefore, a professional removal program should be used to remove any dangers and malicious files from the system and the registry.

    The Registry may be closed after you are certain that it is clean. 

    Next, using the Windows Search Field, type each of the following locations (including the percent symbol) and open them to see if any new items have been added to them:

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

    Just keep an eye out for any new files in the four locations listed above. No: 5 is the Temp folder. Once you open it, select and remove everything, including the temporary files that the ransomware may have created.
