Gerber ransomware removal instructions

What is Gerber?

Discovered by Emmanuel_ADC-Soft, Gerber is categorized as malicious software (ransomware) that blocks access to data by encryption. Once a computer is infected, it renames each locked file by adding the ".gerber5" extension (the extension contains a unique ID that is assigned to each victim individually). For example, "1.jpg" might become "1.jpg.!!BVINO!!.MrAlex.gerber5", and so on. Gerber also generates a "Decrypt.TXT" text file, a pop-up window, and changes the desktop wallpaper, all of which present ransom messages.

The pop-up window and "Decrypt.TXT" file contain information about how to contact Gerber developers to decrypt the locked files. According to cyber criminals, victims have infected their computers due to 'security problems'. They provide an email address ( to contact them. Gerber's victims are encouraged to send the provided "Decrypt.TXT" text file, which contains a personal ID (in our example, ".BVINO"). When contact is made, the criminals supposedly give further instructions, such as cost of decryption key/tool, cryptocurrency wallet for payment, and so on. The ransom note placed on the desktop is virtually identical, but also includes a warning that urges Gerber's victims not to use any other decryption tool, since this might damage encrypted files (cause permanent data loss). They state that only they can provide a decryption tool. This is usually accurate, since most ransomware developers use cryptography algorithms (symmetric or asymmetric) that create unique keys. These are stored on remote servers controlled only by them. This makes free decryption virtually impossible. Furthermore, there are currently no tools capable of decrypting Gerber-encrypted files free of charge. The best way to retrieve encrypted data in these cases is to use an existing backup and restore files from there.

Many cyber criminals use ransomware viruses to blackmail victims. Some examples are Santa, .shadow, and Outsider. Most of these infections are very similar: they block access to data unless ransoms are paid. A cryptography algorithm is often used for encryption, and the ransom size is usually the only difference. Unfortunately, these encryptions are impossible to crack without the involvement of cyber criminals (in this case, Gerber's developers) unless the virus is not fully developed or has bugs/flaws. To prevent data loss caused by ransomware, maintain regular backups and store them on remote servers or unplugged storage devices.

How did ransomware infect my computer?

Cyber criminals often proliferate ransomware-type infections through spam campaigns, trojans, untrustworthy software download channels, and fake software updaters. Spam campaigns are used to proliferate infections through malicious attachments. The main purpose of these campaigns is to trick users into opening the infected attachment. This usually results in download/installation of malicious software. Trojans are malicious programs that often proliferate others (causing chain infections). Untrustworthy software download sources such as peer-to-peer networks (torrents, eMule, and so on), freeware download websites, free file hosting pages and other similar channels are also used by cyber criminals. In these cases, computers become infected when criminals present malicious executables (or other files) as legitimate - users are tricked into downloading and installing computer infections. Fake updaters are used to download and install viruses rather than the updates - these updaters are also capable of exploiting outdated software (bugs or flaws).

Threat Summary:
NameGerber virus
Threat TypeRansomware, Crypto Virus, Files locker
SymptomsCan't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (usually in bitcoins) to unlock your files.
Distribution methodsInfected email attachments (macros), torrent websites, malicious ads.
DamageAll files are encrypted and cannot be opened without paying a ransom. Additional password stealing trojans and malware infections can be installed together with a ransomware infection.

To eliminate Gerber virus our malware researchers recommend scanning your computer with Spyhunter.

How to protect yourself from ransomware infections?

Handle emails received from unknown/suspicious/untrustworthy email addresses (especially those containing attachments) with care. Do not open attachments in emails that seem irrelevant. Download software using official and trustworthy channels, such as official websites. Avoid using P2P networks, dubious websites, and other sources. Update installed software using implemented functions or tools provided by the official developers only. Have a reputable anti-virus or/and anti-spyware software installed and keep it enabled. These tools can prevent threats/computer infections. If your computer is already infected with Gerber, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

Step 2

Log in to the account infected with the Gerber virus. Start your Internet browser and download a legitimate anti-spyware program. Update the anti-spyware software and start a full system scan. Remove all entries detected.

If you cannot start your computer in Safe Mode with Networking, try performing a System Restore.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.

Boot your computer in Safe Mode with Command Prompt

2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.

system restore using command prompt type cd restore

3. Next, type this line: rstrui.exe and press ENTER.

system restore using command prompt rstrui.exe

4. In the opened window, click "Next".

restore system files and settings

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 Gerber 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 Gerber 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 Gerber 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 Gerber, 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 Gerber 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 as well as 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 additional protection layer from ransomware infections.

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