Les Virus – DetailsThe 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.

Bear in mind that the web is now overwhelmed with threats that look similar to Les ransomware. Harmful programs of such kind are usually elaborated to encrypt important information and to state the demand before the user to pay the ransom. The peculiarity of all such ransomware threats is that all apply a similar algorithm to produce the distinct decryption key for files decryption.
Therefore, as long as the ransomware is still being developed or has some hidden bugs, manually recovering the information is simply not feasible. The only way to avoid the loss of your important files is to frequently create backups of your important information.
Keep in mind that even if you create such backups, they need to be put into a special storage utility not connect to your main PC. You may use the USB Flash Drive or external hard disk drive for this purpose, or refer to the help of the cloud storage. If you store your backup files on your common system they may be encrypted in addition to other files, so it’s definitely not a good storage place.
