Les Virus Removal Guide (+Decode .les# files) – Scarab Ransomware

Les Virus – Details

The Les mean a ransomware-type infection. The infection comes from the Scarab ransomware family. Les was elaborated particularly to encrypt all major file types. Once the file is encrypted people are unable to use them. Les adds the “.les#” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by Les, will be renamed into “myphoto.jpg.les#“. As quickly as the encryption is completed, Les places a special text file into every folder containing the encrypted data.

The message given by Les text file requesting for the ransom is absolutely the like the statements given by other ransomware virus representatives coming from the Scarab family. It actually points out that the info is encrypted which the only way to bring back it is to use a a special decryption key. Unfortunately, this is absolutely true. The kind of cryptography mechanism used by Les is still not properly examined. Still, it is absolutely certain that each victim might be given the specific decryption key, which is completely unique. It is difficult to bring back the files without the key available.

Another trick of Les is that the victims cannot access to the key. The key is saved on a particular server run by the frauds connected with Les ransomware. To get the key and recover the important info people have to pay the ransom.

However, irrespective of the requested amount, people should stay away from paying the ransom virus. Cyber frauds are unfair, so they tend to entirely disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom usually does not give any positive result and people simply waste their money for nothing.

We highly encourage that you do not contact these crooks and definitely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Les ransomware and to recover the data data totally free. Therefore, the only best decision is to recover the lost data from the available backup.

This is the typical trick used by online frauds to persuade people into downloading and installing Les infection manually, by methods of their direct participation in the installation process.

So, they may describe to sending unsolicited spam e-mails with tricky notices promoting users to download the attachments or click on certain download links, for example, the ones encouraging users to open some video, documents, tax reports or invoices.

When it comes to the cracked software, these illegally downloaded programs may also contain harmful codes causing Les secret installation.
