Hermes837 ransomware removal instructions
What is Hermes837?
Hermes837 is a malicious software which is classified as ransomware, the person who discovered is GrujaRS. As a rule, ransomware-type programs are designed to encrypt data (make files inaccessible). Cyber criminals spread programs of this type to extract money from people by forcing them to buy decryption tools or/and keys from them. Hermes837 adds the ".hermes837" extension to the filenames of all encrypted files. For example, it renames "1.jpg" to "1.jpg.hermes837", and so on. Instructions on what to do next are provided in the "!!!READ_ME!!!.txt" file.
To get instructions on how to purchase decryption tool or/and key victims have to contact cyber criminals via email@example.com. Email must include country and city, ransom note ("!!!READ_ME!!!.txt" text file) and a couple of encrypted files that Hermes837 developers supposed to decrypt for free. These files should be pictures or text files that are no larger than 1 Mb. If attached files will be databases, then cyber criminals will double the price of decryption tool or/and key. One way or another, all further information supposed to be provided after contacting Hermes837 developers. However, we do not recommend to contact or pay these (or any other) cyber criminals: quite often victims who pay them get scammed. In other words, they pay a ransom but do not get anything in return. Unfortunately, most of the times ransomware developers are the only ones who can provide tools that can recover encrypted files. Typically, decryptions without their tools are impossible. Since cyber criminals should not be trusted, we recommend to avoid data and financial loss by restoring all files from a backup.

There are is a great number of other software of this type out there, for example, Guarded, NextPharma and Meds. Most of them are designed to encrypt data so that ransomware developers could force victims to pay a ransom. Two most common differences are cryptographic algorithm (symmetric or asymmetric) that is used to encrypt data price of a decryption tool and/or key. As a rule, ransomware developers are the only ones who can help victims to decrypt their files, unless a program is not finished (has bugs, flaws, etc). To avoid data loss caused with ransomware we recommend to always have data backed up and keep it on an unplugged storage device or remote server like Cloud.

How to protect yourself from ransomware infections?
We recommend to think twice before opening attachments or links presented in irrelevant emails that are received from suspicious, unknown addresses. Quite often emails of this type are sent by cyber criminals who seek to proliferate one or another malware. Third party downloaders, installers, and other untrustworthy download or installation channels/tools are often used to proliferate malicious programs. The safest way to download programs is to use official websites and direct download links. Installed software should be updated using implemented functions or tools that are provided by the official developers. The same applies to software activation. Besides, third party tools ('cracking' tools) are illegal and can be designed to install malware. And finally, operating systems should be scanned with a reputable anti-virus or anti-spyware software regularly, if they detect any threats, they must be removed immediately. If your computer is already infected with Hermes837, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Hermes837 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 Hermes837 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.
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 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 Hermes837 ransomware.
Note that Windows 10 Fall Creators Update includes "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default this feature automatically protects files stored in Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.
