Msop Ransomware

Msop Ransomware is a threat you might find on your system if you are not careful enough while surfing the Internet or if your system has any weaknesses. If it happens, all of your files could become encrypted as the malware enciphers data on infected devices with a strong encryption algorithm. Files that get affected ought to be marked with the .msop extension, and you should be unable to open them. To restore files, the malicious application’s developers may propose you pay a ransom to get decryption tools that could decrypt all of your files. You should understand that doing paying a ransom might be very risky and that your money could be lost in vain if hackers choose not to help you after all. Consequently, we recommend considering your options with extra care if you detect this malicious application on your system. For users who want to erase Msop Ransomware at once, we recommend using the deletion instructions placed below or a reliable antimalware tool that could get rid of this infection.

Before explaining the malware’s working manner and its deletion, we believe we should tell you more about is possible distribution channels. Our researchers say that many threats like Msop Ransomware are spread through Spam emails, unreliable file-sharing websites, untrustworthy pop-ups or other ads, and so on. In other words, victims may receive it after opening files obtained from questionable sources. Therefore, we advise being extra cautious with files from the Internet if you are not sure you can trust them. Always have in mind that malicious installers do not necessarily have to look dangerous or suspicious. Some of them look like text documents, pictures, and other harmless files. Thus, recognizing potential threats from just looking at files you encounter while browsing might be impossible. Instead, we advise scanning files that do not come from trustworthy sources with a reliable antimalware tool that could tell you if your encountered data is safe to interact with.

The first thing Msop Ransomware should do after getting in place copies of its launcher. Next, it should create a Registry entry and a scheduled task that might make your computer launch the malware automatically every time you restart it. The next thing that the malware ought to do is find the files it is supposed to encrypt. Our specialists say that the malicious application could encrypt photos, various documents, and so on. If a file gets locked, it should receive a second extension called .msop, for example, document.doc.msop. If you try opening such files, you should notice that your computer does not recognize them anymore. Also, you should find a text document called _readme.txt that might appear on your Desktop or in folders where encrypted files are located. Opening this document should reveal a ransom note written by the Msop Ransomware’s developers. It ought to start with the following lines: “ATTENTION! Don't worry, you can return all your files!”

The rest of the malicious application’s ransom note’s text ought to explain what happened to a victim’s data and how it can be restored. To be more precise, the malware’s note should suggest paying a ransom in exchange for receiving decryption tools that would decrypt all affected files. While the threat’s developers may have such tools, there are no guarantees they will deliver them after they get the payment. In such a case, users who pay ransom could lose their money for nothing. If you do not want to risk getting scammed, we advise not to trust the Msop Ransomware’s developers.

Lastly, we recommend erasing the malicious application as soon as possible because if you leave it installed, it could put your future files (files you might yet create or download) in danger. That is because the threat could be able to restart with the operating system, and, as a result, it might start the encryption process once again and affect your new data. If you want to prevent this and decide to eliminate Msop Ransomware, you could try completing the instructions located below to learn how to delete it manually.
