Gesd virus file extension – are your files encrypted with it? If so, then your system has been attacked by a severe crypto infection, which is another iteration of the infamous STOP ransomware. The Gesd ransomware is designed to target your personal data and encrypt them via a strong encryption algorithm. Once this process is finished, you can’t operate with your files until they are decrypted.
Gesd Virus
Аs already mentioned, Gesd is part of the STOP ransomware family which has been releasing new variants quite often. At the moment, Gesd files are not decryptable.
The Gesd ransomware drops a ransom message file, _readme.txt, on the infected system to blackmail victims to pay a ransom fee for the alleged decryption of their files.
This article will provide you with instructions on what to do, once your files have been encrypted with the .gesd extension.

Gesd Ransomware – Full Description
Gesd virus is a crypto virus that was just detected in active attack campaigns. The virus is an iteration of the popular STOP DJVU Ransomware. The distribution of the Gesd virus is believed to be happening via malspam (malicious spam).
Malspam campaigns ensure cybercriminals that their ransomware will reach a large userbase, as it is a relatively easy method which has proven to be efficient. Malicious emails usually contain malicious code hidden in commonly used file types, such as documents and archives attached to the email message. In most cases, such malicious emails pretent to be send by legitimate sources, such as largely known organizations and companies.
NOTE. You should know that files which should activate the Gesd virus on Windows can be:
- Invoice coming from reputable sites, like PayPal, eBay, etc
- Document that appear to be sent from your bank
- An online order confirmation note
- Receipt for a purchase
- Tax bill
These documents could be part of a phishing scheme in attempt to make the potential victim download the payload of the Gesd ransomware.
Gesd Attack Stages
The attack is initiated when the Gesd infection file is executed on the victim’s system. Current ransomware variants are usually more sophisticated than older ones, and they can perform various malicious activities that seriously disrupt the operating system. Furthermore, by adding malicious entries under specific registry keys, the ransomware can become persistent.
Did you know that once the Gesd virus affects the key RUN, it can start its malicious files on each system reboot. Thus, the best advice we can give you is to check your system’s registries and clean malicious entries while also removing Gesd ransomware from your system.
Long story short, the sole purpose of all malicious stages of the ransomware operation is the encryption of your files. For the encryption to take place, the Gesd virus launches a built-in cipher module after it scans specific folders for certain file types typically utilized for storage of personal data.
Each time the module detects a target file, it applies changes that alter the original code of the file to encrypt it.
Other variants of STOP ransomware such as righ and msop, utilize sophisticated cipher algorithms such AES and RSA, and this is most certainly true for the Gesd iteration.
Once the encryption stage is finalized, the virus drops the _readme.txt ransom note, which should say the following:
ATTENTION!
Don’t worry, you can return all your files!
All your files like photos, databases, documents and other important are encrypted with strongest encryption and unique key.

At this point, Gesd is not decryptable with neither Emsisoft’s STOP Djvu Decryption tool, nor with the previously created tool from Michael Gillespie.
However, as soon as we notice security researchers’ announcement about an update that supports the decryption of Gesd ransomware, we will update this article with the latest information.
Remove Gesd Ransomware – Instructions
The so-called Gesd ransomware is a threat with a highly complex code that disrupts system security in order to encrypt personal files. Hence the infected system could be used in a secure manner again only after the complete removal of all malicious files and objects created by the Gesd virus. That’s why we recommend that all steps presented in the removal guide below to be completed. Beware that the manual ransomware removal is suitable for more experienced computer users. If you don’t feel comfortable with the manual steps, you can refer to the automatic part of the guide.

Step 2: Uninstall Gesd and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by Gesd on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by Gesd there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove Gesd
Step 5: Try to Restore Files Encrypted by Gesd.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
