Gomer virus Removal Guide
What is Gomer ransomware?
Gomer ransomware – data locker that can prevent access to personal files until the ransom in Bitcoin is paid
Gomer ransomware is a type of malware that might result in permanent loss of pictures, videos, music, documents, and other files
Gomer ransomware is a file locking virus belonging to the Outsider crypto-malware family and was first spotted by security researcher dnwls0719 in late June 2020. Once inside the system, it encrypts all the pictures, videos, music, MS Office, PDF, and other files with the help of the RSA encryption algorithm. As a result, victims are unable to access any of the personal data located on the PC. Besides, all the files are marked with .gomer extension and are missing their original icons.
Another sign of the Gomer virus infection comes right after that – a text file called GOMER-README.txt is dropped on users' desktop. This ransom note explains what happened to the hosts' files and that, allegedly, the only way to recover them is by paying an unknown amount of ransom in Bitcoin for the Gomer ransomware decryption key. However, victims should not contact cybercriminals via the provided email@example.com email, as they might never receive the promised tool.
|Type||File locking virus, crypto-malware|
|File extension||All personal files are appended with .gomer marker|
|Ransom size||Unknown, although previously crooks asked for 600 Eur in Bitcoin and sometimes Dash cryptocurrency|
|File decryption||The best way for data recovery is backups. However, if such were not retained, CERT Polska might be able to recover data for free. To contact it, please write an email at firstname.lastname@example.org and attach the ransom note along with a few encrypted files. If that does not help, check for alternative solutions below|
|Removal||Download and install reputable security software and perform a full system scan|
|System fix||In some cases, malware can negatively impact the performance of a Windows machine. You can attempt to fix damage that was done by a virus infection with the help of ReimageIntego repair software|
It is yet not completely known how Gomer ransomware is spread, although cybercriminals typically use multiple attack vectors, including:
- Spam email attachments and hyperlinks
- Exploit kits and software vulnerabilities
- Software cracks and pirated program installers
- Unprotected Remote Desktop (RDP) connections
- Malicious advertisements, etc.
Regardless of how the virus accessed your machine, however, the result always remains the same – your data gets encrypted. However, you should not panic and first focus on Gomer ransomware removal that should be achieved with the help of powerful security software, such as SpyHunter 5Combo Cleaner or Malwarebytes.
The contents of the ransom note are as follows:

There are several claims that the malicious actors behind the Gomer file virus are trying to make. For example, they are the only ones who can restore the encrypted data, although it is not true. They also offer a free decryption service for one file. All these promises are made for victims not to doubt the integrity of these statements and pay the ransom.
It is yet unknown what is is the amount that the attackers are asking for, although the payment is meant to be performed with the help of Bitcoin cryptocurrency. This is the most preferred method that ransomware developers use, as it allows them to stay anonymous when retrieving the money. In previous versions of Gomer ransomware, threat actors were asking for 600 Euro, although this can vary from victim to victim.
Regardless, security researchers from dieviren.de do not recommend contacting cybercriminals, as they might simply never send you the promised Gomer ransomware decryption tool, and you will end up losing your money for good.
Instead, you should rely on alternative data recovery solutions – there are several options available, as we explain in the recovery section below. However, you should first remove Gomer ransomware from the system, and only then try to restore your files.
Gomer ransomware is a file locking virus that belongs the the Outsider malware family
For that, you should employ powerful security software and perform a full system scan. You should note that removing the virus will not allow you to open .gomer files, as data encryption and malware infection processes are separate. Thus, do not expect that the anti-malware program will restore your files to the way they were prior to the infection.
Ransomware infection methods and prevention steps
As mentioned above, there are several ways how you could have got your computer infected with ransomware, as cybercriminals commonly use several different techniques in order to affect a broader spectrum of victims. Nonetheless, some strains, such as Djvu, have seen immense success by only using software cracks for the delivery. However, you should equip your computer with comprehensive security solutions and apply adequate measures to prevent ransomware infections in the future.
Once the infection spreads on the PC, files immediately get encrypted. Even if the malware is removed, the encrypted data cannot be opened – this is the main trait that results in such devastating consequences for users, as they might lose their precious photos, school work, and much more.
To protect your machine from ransomware attacks, follow these steps:
- Employ powerful security software and keep it updated;
- Enable Firewall and use ad-block;
- Always patch Windows and the installed software with the latest security updates;
- Protect all your accounts with secure alphanumeric passwords;
- Never download software cracks or pirated program installers.
Remove Gomer file virus and recover your files without contacting cybercriminals
While many ransomware viruses delete themselves as soon as they finish the encryption process, some leftovers may remain. Additionally, it can also come along with other infections, so it is important to make sure that Gomer ransomware removal is performed properly.

How to prevent from getting ransomware
Stream videos without limitations, no matter where you are
There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.
Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.
Data backups are important – recover your lost files
Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.
While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
