Miis Virus


Miis is a Ransomware virus that can apply encryption to all files stored on your computer. Typically, Miis can target work-related or personal documents, images, video and audio files, as well as system records with the idea to demand money for their decryption.

If you’ve come across this post, you probably have been looking for a way to remove Miis,Leex, Neer or Piiq from your computer. That’s why, in the next lines, we will do our best to help you. The two most obvious symptoms of a Ransomware infection are the appearance of a ransom-demanding message that lets you know about the demanded ransom and your inability to access most or all of your files that are on the attacked computer. The crooks may set a short deadline for the ransom payment and threaten that if you don’t pay on time, they will double the ransom or leave the file encrypted forever. Naturally, receiving such a message can be very frustrating but security experts advise victims not to panic. There are methods that may potentially help with the removal of the infection and the recovery of the encrypted files and it is worth trying them out.

The Miis virus

The Miis virus is an infection based on Ransomware encryption that restricts access to digital files without a warning. The Miis virus can encrypt different files stored inside a computer and demand a payment in cryptocurrency to decrypt them.

The Miis virus sneaks in your computer without your consent and silently gets down to business. Its first job is to scan the entire system for specific file types and once it detects them, the Ransomware will start encrypting them one by one. After that, it will generate a warning message, informing you about the encryption that has taken place and the methods to pay for reversing it. Typically, the money you are required to transfer is to “buy” a private decryption key from the hackers who are behind the Miis virus. This key is necessary for your encrypted data to be converted to its previous state.

An interesting fact about Ransomware is that those threats are oftentimes distributed via Trojan Horses that backdoor them into the systems of their potential victims. The Trojan-Ransomware combination can often be distributed via large-scale spam email campaigns, malicious file attachments, torrents, cracked software installers, or malvertisements. The actual infection happens the moment the user clicks on the transmitter, downloads the malicious file or installs the infected setup package. That’s why we always advise our readers to keep away from shady web links, spam messages, cracked software installers or email attachments, especially when they come from unreliable sources and unknown senders.

The Miis file encryption

The Miis file encryption is an advanced code that can restrict access to specific files until a ransom is paid. Decrypting the Miis file encryption is a complex process that requires a decryption key which can only be obtained from the hackers behind the Ransomware.

If you don’t know how to deal Miis we strongly recommend that you don’t hurry to complete the ransom payment that the hackers want from you. For one, there’s just no guarantee they will keep their word and give you the encryption key. And, secondly, even if they send the key and it works, if the Ransomware has not been removed from the system, all the decrypted files may get encrypted again and you will be back to where you started. That’s why, before considering the ransom payment or trying any file-recovery methods, we encourage you to first remove Miis with the help of the instructions in the guide below.



Name Miis
Type Ransomware
Danger Level High (Ransomware is by far the worst threat you can encounter)
Symptoms Very few and unnoticeable ones before the ransom notification comes up.
Distribution Method From fake ads and fake system requests to spam emails and contagious web pages.
Detection Tool

Before you start The following are important notes that we must make before we begin the removal guide for Miis:
  • Firstly, it’s probably best if you keep your PC disconnected from the Internet for the duration of the guide – this is to prevent the virus from communicating with the server of the hackers who are using it.
  • Secondly, it’s also important to keep any external HDDs, flash memory sticks, smartphones, or other devices with storage space of their own disconnected from your PC while the Ransomware is in the system. Otherwise, the files that are stored on those devices may get encrypted as well.
  • Thirdly, for those of you who are thinking about paying the ransom (this is an option that we do not encourage), it is probably better to delay the Miis removal for after you get the decryption code. If you first remove the virus, you may not be able to get the decryption code even if you pay the ransom.
  • Finally, in many cases, Ransomware viruses automatically remove themselves from the system so as not to leave traces that may help with the decryption of the files. Even if it seems that Miis is gone, however, we still recommend competing the next guide for just in case.
Bear all those factors in mind while going through the next steps.

Remove Miis Ransomware

To remove Miis from your PC and prevent further encryption of important data, here are the steps you will nee to complete.

  1. Delete any rogue/questionable programs that could be what caused the infection in the first place.
  2. See if there are Ransomware processes that are still running in the system and quit them.
  3. See what settings changes the virus has made in the system and revoke those changes.
  4. Locate any malware files created in your system and delete them.

You will learn how to complete each of these four steps in the next lines.

Detailed Guide


The easiest way to find out if there are any suspicious and potentially unwanted programs on your computer is to go to Start Menu > Control Panel > Uninstall a Program and to look at the items there. If you have a program on the computer that has caused the infection, that program would likely have a creation date close to the supposed time of the infection with Miis. Pay attention to what the creation dates of the different programs are in that list and if you see one that looks questionable and was installed just before Miis encrypted your files and revealed itself, then you should probably uninstall that program.

Note: Some uninstallation wizards offer to keep settings for the program on the computer – refuse any such offers from the uninstaller of the unwanted program.

All processes currently running on your computer can be seen in the Task Manager’s Processes tab – go there by pressing Ctrl + Shift + Esc and by clicking on the Processes tab from the top.

In most cases, the Ransomware processes should no longer be running. However, if there’s a process related to Miis that’s still active, it will likely have high RAM memory and CPU usage, so look for any oddly-named processes among the ones with the highest resources consumption (you can sort the list based on how much memory or CPU they are using).

If you deem a certain process suspicious, it’s best to first try to find some more information about it by searching for its name on the Internet – if the process is harmful, it won’t be long before you find reports from security researchers saying that.

Another method to check a given process is to right-click it, to open the File Location folder, and to scan the files there in order to see if they contain malware code. There’s a free online scanner down below that requires no installation – we recommend using it to scan the files in the location folder of the suspected process.

    If a file gets flagged as a threat, the first thing you should do is quit the process, as shown in the next image. After that, you should delete everything in the location folder and the location folder itself, and not only the file/files that got detected as threats. If something can’t be deleted now, try again after you complete the guide.

    Keeping your PC in Safe Mode during the next steps is important, as this could prevent the Ransomware from re-launching its malicious processes and potentially disrupting your progress.


    The next thing you have to do is visit several folders where rogue malware data is likely to have been created and delete said data. However, before you go there, you must make the hidden files and folders on your computer visible because malware programs often times tend to make their malicious files hidden for obvious reasons.

    Star by going to the Start Menu, typing Folder Options, and selecting the first shown icon from the results. In the next window, open the View tab and in it find and check the Show Hidden files, folders, and drives option. After that, uncheck the following two options and then click on OK:

    • Hide extensions for known file types
    • Hide empty drives in the Computer folder

    Now you should make hidden files and folders on your PC visible and then find and delete any Ransomware data present on your PC.

    Next, copy the lines from below, place them one by one in the Star Menu, and press Enter after each.

    • %AppData%
    • %LocalAppData%
    • %ProgramData%
    • %WinDir%
    • %Temp%

    Now delete everything created since the date of the virus’ arrival on your PC in all of those folders, except the Temp one. When you get to the Temp folder, simply select all files and folders located in it and delete them.


    There are several likely settings changes that Miis may have made in the computer, and you need to revoke them. The first settings you should check are the list of startup items. You can go to it by typing msconfig in the Start Menu, opening the first shown icon, and then opening the Startup tab in the System Configuration window.

    In there, look for anything unfamiliar or with an unknown developer, uncheck any such items, and then click on OK.

    Next, another thing you should check is the computer’s Hosts file. You can find it in Computer/(C:)/Windows/System32/drivers/etc – once you get there, open the Hosts file using the Notepad program and see if anything is written after the second Localhost word. If there’s text written there (would usually be a bunch of odd-looking IP addresses), copy the text and send it to us by writing us a comment below this guide.

    Next, wait for our reply – we will soon have a look at your comment, determine if the text from your Hosts file is related to the virus, and reply to you, telling you if anything needs to be done in the Hosts file.

    Finally, go to the Registry of your system – any way to access it is to simply type regedit in the Start Menu and then select the regedit.exe app from the search results. Windows should ask for permission to start the app, so click on Yes to provide it (you have to be the computer’s Admin to be able to open this app).

    When you start the Registry Editor, open its search bar by clicking on Find from the Edit menu. Then type the name of the virus and search for it – anything that gets found must be deleted but since the search will give you only the first related item, you will have to repeat the search to see if there are others in order to delete them.

    This image has an empty alt attribute; its file name is 1-1.jpg

    Delete all results for Miis so that nothing more gets found when you perform this search, and then navigate to these three locations in the left pane of the Editor.

    • HKEY_CURRENT_USER > Software
    • HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Run
    • HKEY_CURRENT_USER > Software > Microsoft > Internet Explorer > Main

    In them, you may or may not find items with random and odd-looking names that look like this “d2903ut289j3f89th3984hf9204j390rj0” – if you find anything like this there, delete it. If you come across a suspicious item, but you aren’t sure it must be removed, contact us through the comments section, and we will tell you what to do.

    If the manual steps didn’t help Of course, it is possible that trying to manually remove the virus may not always work – there are many factors that may prevent you from deleting such an advance threat all by yourself. A common example would be if the virus is being helped by another malicious program (a Trojan or a Ransomware for example) that is keeping the Ransomware data hidden or is restoring it after you delete it. Whatever the cause for the persistence of Miis, if you haven’t been able to remove it thus far with the help of the instructions we showed you, it is recommended to scan your entire system with a professional malware-deletion tool that can find and get rid of all harmful data and settings that are in the system. One such tool that we highly recommend can be found linked in the current guide – it should be able to take care of Miis as well as eliminate any other sneaky malware that may be hidden on your computer.

    How to Decrypt Miis files

    To decrypt Miis files, you must first make sure that the Ransomware is deleted, after which you can use some of the alternative data-restoration methods. To decrypt Miis files, you can also pay the ransom, but this is inadvisable because you can’t trust the blackmailers.

    It is very important to be sure that the virus is gone if you are going to use the alternative recovery methods for your files because, if the Ransomware is still on the computer, it may interrupt the recovery process or even re-encrypt any data you may manage to restore. Remember that the free scanner offered on our site is always there for you if you need it to check any suspicious files on your computer that you think could be from the Ransomware.

    Once you have made sure that the system is clean, we suggest you check the methods and instructions show in our How to Decrypt Ransomware post and use them to hopefully bring back your files.
