Igdm ransomware – a cryptovirus that urges victims to pay the ransom within 72 hours to receive a 50% discount
Igdm ransomware is a computer virus that encrypts all non-system files on a targeted computer as soon as it accesses it and demands a ransom to be forwarded in cryptocurrency Bitcoins for a decryption tool. During the encryption, all personal files like archives, pics, videos, documents, and so on are renamed by appending .igdm extension to them.
After successful encryption,[1] virus creates ransom notes, titled _readme.txt, with detailed instructions for the victims and places them in each folder on the infected computer containing locked files, so the victims would find these notes literally wherever they look.
.igdm file virus belongs to the infamous Djvu ransomware family, that has over 250 cryptovirus version frightening everyday computer users since December of 2018. One thing that never changes with this family's parasites is the email addresses meant to contact the cybercriminals – helpmanager@mail.ch and restoremanager@airmail.cc.

Message in the ransom note from Igdm ransomware is almost identical to the ones from all of its previous versions, such as Weui, Lisp, Nobu, and others (the whole message is displayed below). Hackers begin by explaining to the victims that all their files were locked, but they can be restored with the help of a decryption tool that must be bought from the assailants.
To show good faith, the cybercriminals offer free decryption of one file from the infected computer to prove to their victims that such a tool exists and intend to share it. Furthermore, they include a link to a video where the said key can be seen in action.
The benevolence of the criminals doesn't end there. They offer a 50% discount for the ransom amount (lowering it to $490) if the victims contact them within 72 hours of the attack. Otherwise, if the users aren't hasty, the Igdm ransomware decryption tool's asking price is $980.
At the bottom of the ransom note, the perpetrators specify the victim's personal ID and provide two emails to establish contact with them. As always, we advise against dealing with the criminals and recommend victims to remove Igdm ransomware from all infected devices.
There are two ways for Igdm ransomware removal. Users can do it manually with our free guide posted at the bottom of this article or by performing a full system scan with a dependable anti-malware app like SpyHunterCombo Cleaner or MalwarebytesMalwarebytes. Whichever method you choose, do it swiftly before more harm is done to your device.
Experts[2] recommend using system repair tools like the FortectIntego to tune-up the system after the infection is eliminated. Cryptoviruses are known to modify the system registry and other key system settings to help them with their bidding. If neglected, these changes might cause anomalous device behavior.

Ransomware distribution techniques and possible data recovery options
Hackers use different malware distribution techniques, but as our research shows, almost all cryptoviruses from the Djvu ransomware family are spread with various software cracks.[3] Most of the infections happen when computer users download these illegal activation toolkits from websites like The Pirate Bay, eMule, and others.
Most ransomware encrypted files can never be unlocked without the intervention of their developers. Government and private organizations are issuing projects like NO MORE RANSOM! to help people get their data back. But one company, called Emisoft, is specializing in decrypting ransomware from the Djvu family. They might not have the necessary tools at this moment, but be sure to check back either with them or with us for the latest updates.
Of course, if you had backups of your sensitive information, then you don't need to worry about any decryption tools. Eliminate the virus, tune-up your system, and restore your data. But since the cryptovirus got through, we suggest investing in better anti-malware software and staying away from file-sharing platforms.
Instructions on how to remove Igdm ransomware from infected devices
Before doing anything, victims of a cyberattack should extract all encrypted files from the infected computer to an external storage device. That's necessary for computer users that didn't keep backups. Only then should they think about Igdm ransomware removal and data recovery options.
We recommend performing a full system scan and removing the cryptovirus with professional, reliable anti-malware software like SpyHunterCombo Cleaner or MalwarebytesMalwarebytes. Although some malware can prevent anti-virus software from deleting it, we're here to help. You can try doing it with your device in Safe Mode with Networking. We've provided a full guide on it just below this paragraph.
Since the Igdm ransomware virus, like any other cryptoviruses, tends to make changes to various core system settings that, for example, could prevent them from visiting any security-related websites (including 2-spyware.com), users should perform a system tune-up with appropriate system repair tools like the FortectIntego app.
