Major ransomware removal instructions

What is Major?

Major is a malicious program, classified as ransomware. Credit for discovering it belongs to GrujaRS. It is designed to encrypt data and keep it locked, until a ransom is paid (i.e. decryption tools/software is purchased). As the encryption is underway, all files are appended with the victim's unique ID number, Major's developers' email address and the ".AIR" extension. For example a file titled "1.jpg" would appear as something similar to "1.jpg.33868453691972502380.ex_parvis@aol.com.AIR", and so on for all of the affected files. After this process is complete, an HTML file - "TRY_TO_READ.html" is created on the desktop. The wallpaper of the desktop is also changed.

The text presented on the wallpaper states that all of the victim's data has been encrypted. It users them not to attempt manual decryption (i.e. without the interference of cyber criminals behind the Major infection) - as that will result in permanent data loss. There are three email addresses listed for contacting said criminals. The message in the "TRY_TO_READ.html" file contains identical text to the wallpaper. However, it adds that only they (the developers of Major) can decrypt the compromised files. Victims are told not to attempt decryption with the aid of third parties, as they will get scammed. The message ends with a unique ID number (generated individually for each victim and present in the filenames of affected data). This code must be included in the email users send to the criminals. Unfortunately, it is true that in most cases of ransomware infections decryption with third party software is impossible. Regardless, it is expressly advised against contacting cyber criminals and/or meeting their demands. Often, despite paying - victims do not receive the promised tools. Therefore, their files remain encrypted and worthless. While removing Major will not restore the encrypted data, removal will prevent from further encryptions. The only viable solution is restoring the files from a backup. Given, if one was made before the infection and stored in a different location.

LokfForvNEMTY REVENGE 2.0Corpseworm are a few examples of other ransomware. All malware of this type encrypts data and demands payment for its decryption. However, each infection differs by the cryptographic algorithm (symmetric or asymmetric) the program uses, as well as by the ransom size. These payments tend to range between three-digit and four-digit sums (in USD). Cyber criminals prefer digital currencies (most commonly, cryptocurrencies), as transactions of them are difficult/impossible to trace. Decrypting encrypted files, without the involvement of the ransomware's developers, may only be possible if the malicious software is still in development and/or has certain flaws (bugs). To ensure data safety, it is advised to keep backups in unplugged storage devices and/or remote servers. Ideally, multiple backup copies should be stored in separate locations.

How did ransomware infect my computer?

Malicious content (ransomware and other malware) is typically spread via trojans, spam campaigns, untrustworthy download channels, illegal software activation tools ("cracks") and fake updaters. Trojans are a type of malware, designed to cause chain infections. Spam campaigns are used to send out large numbers of deceptive emails. This mail is usually marked as "important", "official", "urgent", "priority" and similar. They contain attached files (or web-links leading to them), which when opened - cause a system infection. The infectious attachments come in various formats, such as executable (.exe, .run) and archive (RAR, ZIP) files, Microsoft Office and PDF documents, JavaScript, etc. Unofficial and free file-hosting websites, P2P sharing networks (BitTorrent, eMule, Gnutella, etc.) and other third party downloaders are considered to be untrustworthy; therefore more likely to offer malicious content. Illegal activation ("cracking") tools can infect systems, rather than activate licensed product. Fake updaters exploit weaknesses of outdated software and/or simply install malware instead of the promised updates.

How to protect yourself from ransomware infections?

Suspicious/Irrelevant emails should not be opened, especially such received form unknown senders (addresses). Any attachments (or links) found in suspect mail must never be opened; doing so can result in an infection. Only official and verified download sources should be used. It is advised to activate and update software with tools/functions provided by legitimate developers, as "cracking" tools and third party updaters are deemed to be a threat to system health. Users are strongly recommended to have a reputable anti-virus/anti-spyware suite installed and kept up-to-date. Furthermore, these programs are to be used for regular system scans and for the elimination of detected threats/issues. If your computer is already infected with Major, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the Major ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Major ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Major are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by Major, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as Major ransomware.

Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites, and Desktop folders.

Controll Folder Access

Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.

HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
