Iswr is a malicious piece of software that operates as ransomware and encrypts user files without notice. After applying its encryption, Iswr asks its victims to transfer a fixed amount of money to a cryptocurrency account in order to obtain a decryption key.

The Iswr Ransomware will leave a _readme.txt file with instructions

Perhaps, the Iswr infection has come to you completely our of the blue and you are desperately looking for ways to remove it and repair what it has done. Dealing with a ransomware virus (Btos), however, can be very challenging because this type of malware can restrict access to very valuable files and demand a ransom to decrypt them. Although it may be difficult, though, you can still remove Iswr and even recover some of your digital data without paying a ransom. One of the methods that may help you is described in our removal guide below. But this is not everything. If you take a couple of minutes to read the next paragraphs, you will also gain greater insight into Ransomware and be able to efficiently defend yourself from such malware in the future.

The Iswr virus

The Iswr virus is a malicious piece of software that secretly applies encryption to user files and then demands a ransom for reversing it. The Iswr virus can attack the system in secret as it can sneak inside with the help of a Trojan horse or via system security vulnerabilities.

Special encryption is secretly applied to all files that have been saved on the infected machine as soon as the ransomware sneaks in it. The role of this powerful encryption is to prevent users from accessing their records, databases, archives, images, videos, work-related documents and other files that are of great value for them. Once all these files get “secured” by the ransomware, a ransom note appears on the computer and reveals the harmful outcomes. This note contains a message from the cyberciminals behind Iswr which are demanding money for a decryption key. They provide all the requirements about how to pay the amount and generally give you a very short deadline. The crooks do not hesitate to intimidate the victims even with direct threats as their only objective is to make them pay immediately.

The .Iswr file encryption

The .Iswr file encryption is a stealthy process used by cybercriminals to restrict access to user files. The .Iswr file encryption is typically not detected by most antivirus programs as something disturbing and this helps it to slip under their radar.

Iswr File

The Ransomware victims are certainly frustrated in their helpless state where they are unable to access their own information. But this should not be a reason to comply with the ransom demands of some anonymous online crooks. Firstly, no one guarantees that the offenders will send a decryption key after the payment is made. Very often the crooks don’t send anything back to the victims when they get the money. The removal guide below, however, is an alternative that would cost you nothing and may help you not only detect Iswr and remove it from your system but also recover some of your files for free.

As far as prevention is concerned, make sure you protect your system with a decent antivirus and save your most important data on an external device or cloud somewhere else so that you can access them whenever you need to.

*Iswr is a variant of Stop/DJVU. Source of claim SH can remove it.


To remove the Iswr virus, first get rid of any potentially threatening programs on your PC, then try to quit the Ransomware process, and finally revoke any system settings changes made by the virus.

  1. Uninstall any rogue or harmful programs from the Programs and Features list.
  2. Use the Task Manager to find and quit the malware process or processes.
  3. Go to the Hosts file and to the system’s Registry and disable/delete any Ransomware items found in them.
  4. Check these five folders for Ransomware files and delete anyting suspicious you may find there: AppData, LocalAppData, ProgramData, WinDir, and Temp.

For more detailed explanation of how to perform the steps from above, please, read the next lines.

You can go to the Programs and Features list of programs by searching for it in the Start Menu. Once you open it, look at what programs have been installed last, before the Ransomware revealed its presence on the computer. If you see a suspicious program installed around that time period, click on it, the select Uninstall, and perform the uninstallation while making sure that nothing is left from that program on your computer(including your personalized settings for it).

Next, you must search the Task Manager for rogue processes. Open the Task manager tool by pressing the Ctrl, Shift, and Esc keyboard combination and look at the Processes tab. Typically, the Ransomware process would require significant amounts of RAM and processing power (CPU) to function, so focus on the most resource-intensive processes from the list. If any of them seems oddly-named or suspicious in some other way, look up the name of that processes and see what information comes up.

If a reputable source tells you the process may be coming from malware, go to the location folder of that process by right-clicking on the process and selecting the first option. Use the powerful online scanner that you will see below to test each of the files from the location folder for malicious code.

    If you end up finding any malware files in that folder, the entire folder should be deleted but before you try to delete it, quit the malicious process by right-clicking it and then clicking End Process.

    Note 1: If the virus prevents you from deleting any of its process’ files or the file location folder, delete what files you can and go on to complete the other steps. Once they are completed, you should be able to delete the location folder.

    Note 2: If you have a strong reason to believe that the suspected process is from Iswr, quit it and eliminate its files and folder even if none of those files get flagged as malware by the scanner.

    Put the computer in Safe Mode – while in this mode, Windows will keep the Iswr processes from running in case you in’t manage to disable them all in Step 2.



    Place this line of text: notepad %windir%/system32/Drivers/etc/hosts in the Start Menu’s search box and click on the file that show up. If Windows requires you to pick a program from a list of programs to open the file with, choose to open it with Notepad.

    In the file, copy all text written below the “Localhost” line (if there’s any text there) and post it in the comments. We must have a look at your comment, and we will then determine if the text you’ve sent us may be from the virus. If it is, we will inform you in a reply to your comment, in which case you will have to delete that text from the file.





    Warning!: The step you are about to complete requires to find and delete rogue malware items in the System Registry. Before deleting an item from the Registry, you must be certain that the item is unwanted/malicious. If you aren’t sure about that, consult us by writing us a comment rather than directly proceeding with the deletion.

    You can access the Registry Editor utility by typing regedit in the Start Menu and pressing the Enter key. An Admin permission will be required to open the utility so click on Yes when a pop-up dialogue menu appears.

    In the Registry Editor, open its search box by pressing together Ctrl and F and then type the virus name in the box. Perform the search and if there is a search result, delete the found item. You must keep searching and deleting until the search stops yielding any results.

    Finally, you must look for questionable sub-folders in the following Registry directories. You can navigate to those directories from the left panel of the Registry Editor:

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


    If there you find sub-folders that stand out from the rest either because they have unusually long names or because their names look like sequences of random characters, you should probably delete those sub-folders but, again, asking us firs is preferable.


     Lastly, visit the folders listed below by copying the folder name along with the “%” characters and pasting it in the Start Menu search – the folder should show in the results, and you will have to click on its icon to open it.

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

    In each folder, delete only the files created after the moment you think the virus entered the computer. The only folder in which you must delete all files is Temp.
