This page aims to help you remove Gero for free. Our instructions also cover how any .Gero file can be recovered.

The ransomware cryptoviruses like Gero,  CaroteMasodas or Vesrato are a very widespread category of harmful computer programs, which are designed to lock up the files of their victims as a means of extorting money from them. The process of data-encryption is what allows those malicious pieces of software to complete their task of rendering the files of the attacked users inaccessible. One of the worst things about Ransomware infections of this type is the fact that full data recovery may not always be achievable. Even if the user pays the ransom that the hackers would surely demand in exchange for a decryption key for the locked files, the end result may still not be the desired one. It is totally possible that the hackers may not really provide the user who has paid the ransom with the key that can unlock the user’s files. Of course, once the payment is made, the money sent to the hackers is bound to remain there. Even if you do not get to access your files after paying for their decryption key, your money wouldn’t be refunded. This has lead most experts in the field to regard the ransom payment as an inadvisable course of action. We agree with this, which is why we strongly advise you to try to remove Gero and then opt for some potential alternative data-recovery solutions,instead of sending the hackers behind the cryptovirus your money.

The Gero virus

.Gero Virus

You will find this message in a _readme.txt file left behind from the .Gero Virus.

Gero is a new version of Ransomware – one that is currently on the rise, claiming new victims with each day. Like the rest of its malicious category, this one cryptovirus uses its advanced encryption algorithm in order to ensure that you can no longer access your files. As soon as the targeted data on invaded computer becomes inaccessible, the infection makes an offer to its victim – to pay a certain amount of money, sending it to the virtual wallet of the hacker, and in turn be sent an access key that could decrypt the sealed files. As we already pointed out, despite the hackers’ promises, you cannot really be sure whether you’d really get that key once you pay, making the ransom-payment option an undesirable one.

The Gero file encryption

Gero’s file encryption in action

 The main problem with the encryption used by this malware is the fact that there really aren’t that many methods of removing it. Even if you manage to eliminate the cryptovirus itself, your files would still remain inaccessible as long as the encryption is still on them and you don’t have the needed key. However, removing Gero is the first step on the path towards potentially regaining the access to your files through alternative means. Also, the removal itself is important in its own right, as that would make your computer safer for future use, and would prevent the future encryption of more data.

 In the removal guide you are about to see, you will find both removal instructions and some recovery suggestions (in a separate section). Complete the removal instructions first in order to secure your machine, and then try some of the suggested recovery steps. Sadly, we cannot tell you if they’d work in your case, but it is still important to give them a try, as that may allow you to liberate your data without having to pay a ransom.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab. Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections.


Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

hosts_opt (1)

If there are suspicious IPs below “Localhost” – write to us in the comments.

Type msconfig in the search field and hit enter. A window will pop-up:


Go in Startup —> Uncheck entries that have “Unknown” as Manufacturer.

  • Please note that ransomware may even include a fake Manufacturer name to its process. Make sure you check out every process here is legitimate.


To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
