Pezi Virus


Pezi is a file-encrypting virus that is more commonly referred to by the collective term of ransomware. Pezi blocks the files of its victims by applying a strong encryption algorithm to them. After this, Pezi proceeds to blackmail its victims for money in exchange for decrypting said files.

The Pezi virus encryption

Ransomware viruses of this type can typically affect a rather wide range of different file types. Therefore, if Pezi has infected your machine, it likely left no stone unturned, so to speak. This can often prove quite devastating for the infected users, as they may lose access to very valuable information, whether it be work-related or personal. And as a rule, the hackers and cybercriminals behind such malicious code tend to target businesses and larger organizations with their viruses, because those are likely to suffer the most from such attacks and also have deeper pockets to pay for a decryption solution.

Speaking of which, the decryption key is actually what Pezi is requesting that you pay ransom for. This is the key you need to apply to the encrypted files in order to make them readable again.

However, what the hackers don’t want you to know is that there are also alternative means of restoring your infected files. There are free decryptor tools available online, you can try and recover your data from system backups or with the help of shadow copies, etc. We’ve listed all these solutions in the guide below. But before you attempt any of them, you will first need to remove Pezi from your computer, which we’ve shown how to do in the same removal guide below.

The Pezi virus

The Pezi virus is highly dangerous and its encryption may prove difficult to deal with even for experts. What’s more, that very encryption also allows the Pezi virus to avoid detection from security software.

And this curious phenomenon occurs as a result of the fact that encryption is in and of itself not a malicious process. If anything, it’s a very useful and even crucial thing to us in our everyday lives. Encryption allows the transfer of information between a given number of parties while protecting the information from prying eyes (e.g. encrypted text messages, emails, financial data, passwords, etc.). Only in this case the data “protected” is yours and the prying eyes are those not in possession of a designated decryption key.

The .Pezi file

Hackers have started to rely increasingly on malvertisements for the Pezi file distribution. Furthermore, the Pezi file distribution may also be carried out via spam messages.

Usually, these messages will contain some type of link or attachment that the body of the message will try and get you to open under whatever pretext. For example, the message may pretend to come from a popular online store or even a government organization. So it’s important to make 100% sure that whatever emails or other messages you’re interacting with are in fact safe. Otherwise, it’s best you don’t interact with them at all.

Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy
This scanner is free and will always remain free for our website's users.
This file is not matched with any known malware in the database. You can either do a full real-time scan of the file or skip it to upload a new file. Doing a full scan with 64 antivirus programs can take up to 3-4 minutes per file.

    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:

    Pezi Virus

    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!
