Also, our computer security specialists tell us that the threat’s warning should ask to pay ransom. In exchange for paying, the malicious applications creators promise that all the encrypted files will be unlocked. Cybercriminals also threaten to erase files permanently if victims do not comply. Even so, we advise not to rush and consider your options clearly. Thus, whether you found this threat on your computer or want to ensure that it does not get in, we recommend reading our full article.

For instance, the malicious application tricks victims into launching it unknowingly by masquerading as a document. To be more precise, our researchers say that the malware’s installer should have an icon of a PDF file. Therefore, it might not seem harmful just by looking at it, which is why we highly recommend scanning all data that comes from unreliable or unknown sources with a legitimate antimalware tool.

Usually, threats like Math Ransomware are spread through spam emails. Consequently, it is highly advisable not to open attachments if they are sent by someone you do not know. Also, users should especially watch out for files that come with messages saying that it is important to open them right away. In general, messages rushing you to click or open something should raise a red flag. In such cases, it is best to check the sender’s email address because it could be forged. What’s more, the malicious application could also be spread through file-sharing websites, so if you want to protect your system, you should download software only from legitimate sources. Plus, it is safer to let your device download updates automatically as you could end up on malicious websites while looking for the needed updates.Math Ransomware Removal GuideMath Ransomware screenshot

In non-techie terms:

Math Ransomware belongs to the Jigsaw Ransomware family. Malicious applications that belong to it are known for punishing their victims by deleting their files. In this case, the malware claims that at first, it will erase only a couple of hundreds of files and later thousands of them if a user does not pay ransom. Naturally, if you are not planning on paying the ransom to decrypt your files, it should not matter if the threat deletes them as encrypted data is unusable. We advise not to pay ransom not only because there are no guarantees that your files will be decrypted but also because it might be possible to decrypt them free of charge if you use a decryption tool that was created by cybersecurity specialists to restore files affected by Jigsaw Ransomware. Of course, if you decide not to pay ransom, there is no point in keeping the malicious application on your system. We advise deleting Math Ransomware with the removal guide placed above or a reputable antimalware tool.
