.Kaspersky Virus



.Kaspersky is the name of yet another newly developed ransomware cryptovirus.  .Kaspersky is specially created to blackmail its victims by encrypting specific file types in their system and asking the users to pay a ransom for their decryption.

If you’ve landed on “How to remove guide” because you have recently been greeted by a scary ransom-demanding message generated by this new infection, then you are most probably desperately seeking methods to remove the nasty cryptovirus and to get your files restored without paying the ransom that the hackers want from you.

Before you scroll down to the instructions in the removal guide below or give a try to our file-recovery suggestions, however, we need to give you a better idea of what exactly you are dealing with. Representatives of the ransomware category can lead to very serious issues, especially if you have important files in the computer that aren’t backed up properly.

The .Kaspersky virus

Once ransomware like the .Kaspersky virus gets inside the computer, it hides well and secretly completes its criminal agenda. Usually variants like the .Kaspersky virus show close to no symptoms.

An infection like .Kaspersky or Tzw, for instance, can carefully scan the entire PC for a list of file formats (images, documents, audios, videos, archives, etc.) and apply a very complex and unbreakable encryption algorithm to each and every file that belongs to these formats. Once it does that, the malware urges the victims to pay a sum of ransom money in exchange for a special decryption key, which is supposed to liberate the locked files from the complex encryption. Without it, none of the files can be opened or used and those who don’t pay within a given deadline are threatened to never be able access their most needed data again. A ransom note typically provides the information about the file encryption and about the steps that need to be taken in order to carry out the ransom payment and get the decryption key.

The .Kaspersky file decryption

The .Kaspersky file encryption is quite sophisticated and cannot be cracked easily. Typically, for the .Kaspersky file decryption you’d need a special key that the hackers expect you to pay for (i.e. the ransom).

Generally, once you opt for the ransom payment, you can’t really know what to expect. There can be no guarantees about the future of your files and your computer as long as such malware is hiding inside the system. Also, the sum of the ransom asked by the criminals may sometimes be ridiculously high and, unfortunately, even if you pay it and fulfill all of the ransom demands and instructions, there is still a possibility that you may get nothing in return.

The decryption key may not work or the hackers may simply vanish without sending you anything. That’s why we do not recommend that the victims of .Kaspersky contact the criminals and send them money. Instead, we suggest that they use a strong anti-malware program to remove .Kaspersky immediately from their PC and explore alternative methods of file recovery like the ones in the removal from this page.

As far as your future protection against ransomware is concerned, it is important to know that the hackers usually rely on different fake software installers, malvertisements, infected email attachments and spam messages as well as on torrents and phishing sites for the distribution of ransomware like .Kaspersky. They also often use distribution strategies such as social engineering in order to infect as many PC users as possible, all across the globe. That’s why it is important to invest in reliable security software that has specialized anti-ransomware detection and avoid sketchy web locations that may infect you with such viruses.


Danger LevelHigh (Ransomware is by far the worst threat you can encounter)
SymptomsVery few and unnoticeable ones before the ransom notification comes up.
Distribution MethodFrom fake ads and fake system requests to spam emails and contagious web pages.

Reboot in Safe Mode (use this guide if you don’t know how to do it).



Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab. Try to determine which processes are dangerous. 


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

    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:



    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!
