.Gerosan Virus – details

.Gerosan virus is very similar (in fact almost identical) to previous revisions of the STOP ransomware like .Muslat and .Heroset.

The post that you’re about to read is going to present you with essential details regarding a noxious malware piece called .Gerosan.  This insidious software is able to seal all personal documents that the customer has saved on their computer’s hard-drive and place a ransom-demanding message which blackmails them to pay ransom for their liberation. This blackmail scheme is typical for a very malicious type software programs known as Ransomware cryptoviruses. When all of the targeted data has been completely locked up by the cryptovirus, a ransom-demanding pop-up appears on the victim’s computer screen, telling them about the virus attack. The purpose of this type of pop-up would be to give you instructions on how you should actually make the ransom payment to the online crook that’s blackmailing you through the nasty piece of malware. The ransom is typically required in exchange for the decryption key which would enable the targeted user to regain access to the encrypted computer files.

.Gerosan encrypted files – a screenshot

Oftentimes, there is a warning in the ransom pop-up message, associated with the future of the encrypted data – unless you pay the demanded ransom, the data would remain inaccessible for good. In case that the dangerous .Gerosan has already encrypted your personal files and you are in search of a way to resolve the pressing issue, we recommend you to continue reading this article. in this instance it is called a _readme.txt.

Interestingly the emails associated with the virus currently are [email protected] and [email protected]

Removing .Gerosan manually – is it dangerous?

Infections that fit in the Ransomware category are usually different from all other types of viruses. That’s why if you land a Ransomware on your PC you need to know that there is a significant possibility that your software security tool will not be able to spot the virus. The reason behind this has to do with the fact that infections like .Gerosan don’t normally aim to directly damage anything on your Computer and, thus, there is nothing to trigger a security warning from your software security program. This is because the whole process of file encryption that the Ransomware uses is not damaging by itself. File-encryption is a commonly used data protection mechanism which provides one of the safest forms of protection against unauthorized access to digital information. However, when applied by malware from the Ransomware type, this otherwise useful method can easily become a very unpleasant issue because it can deprive the data owner of accessing their personal files. An additional fact about Ransomware that you need to remember is that, generally, there are almost no symptoms of the virus during the encryption process which makes it very difficult to detect and remove on time.

The hackers associated with almost all Ransomware programs, including .Gerosan, rely on the fear and the panic which the victims go through the moment they realize they have no access to their personal files. Unfortunately, many users agree to fulfill the ransom demands with the hope that they will restore their data and transfer the money that the crooks require. We need to warn you, though, that this is not a guarantee for anything because the chance of not obtaining the decryption key even after thoroughly complying with the requirements of the hackers is very high. Not to mention that, if such a key ever exists, it may not be able to reverse the applied encryption properly and may make things even worse. That’s why we don’t recommend our readers to risk their money and suggest them to focus on legitimate solutions which can help them remove the infection and eventually save their files by other means.


Danger LevelHigh (Ransomware is by far the worst threat you can encounter)
SymptomsVery few and unnoticeable ones before the ransom notification comes up.
Distribution MethodFrom fake ads and fake system requests to spam emails and contagious web pages.
