A very stealthy and harmful type of malware that prevents the users from accessing their personal files has recently been reported to our “How to remove” team. The infection goes under the name of .Besub and secretly encrypts the files, stored on the infected computer, and renders them inaccessible unless a special decryption key is applied to open them. In order to receive that key, which can reverse the encryption, .Besub asks the victims to pay a certain amount of money (usually requested in Bitcoins) as a ransom. The blackmailing scheme applied by the infection is typical for a specific malware category known as Ransomware cryptoviruses, and if your files have become a target of it, you definitely may be interested in finding a way to remove the malware and restora your files. That’s why, in the next lines, you will find some important information about the nature of the Ransomware cryptoviruses, and about .Besub in particular, as well as a special removal guide with instructions and suggestions on how to avoid the ransom payment.

How can you get infected with .Besub File?

A Ransomwares such as .Besub, .Litar, .Nusar can infect your computer in several ways. One of the most common methods currently is through malicious emails or spam messages that are used to distribute the harmful payload. In most of the cases, the malicious email message may include some harmful attachments, such as PDF or Word documents, or links to malicious websites, which appear to be legitimate or intriguing and prompt you to click on them or download something.

Another common method of infection is through malicious advertising. Malicious advertising is the use of online advertisements to distribute malware with little or no user interaction. While surfing the web, even on legitimate sites, users may be taken to criminal servers when they simply click on an ad. These servers may be filled with all kinds of threats and you can easily get some nasty Ransomware if you accidentally click on the wrong link or clickbait prompt.

Sometimes, the hackers who create such threats may use an infected image, or a video or an audio, or an invisible element inside webpage to do the job. The infected element redirects to a landing page of an exploit kit and the malicious code attacks the system from it. All this happens without the knowledge of the user, which is why it is often referred to as a drive-by-download attack (by hidden download).

How to deal with .Besub File Virus?

The file-encrypting Ransomware can be very challenging to deal with. This is the one that “kidnaps” the files of the users and demands a payment to decrypt them and return them to the victims. The reason why this type of Ransomware is so dangerous is because once the infection blocks the access to the files, there may be no security software or system restoration capable of returning them completely. Therefore, many users agree to pay the ransom with the hope that they will restore them. However, even if you pay, there is no guarantee that the cybercriminals will send you the decryption key, let alone that it will work and will be able to successfully return the files to their previous state. Therefore, before you risk your money, we suggest you give a try to some alternative methods that may help you remove .Besub and save some of your files without paying a ransom.
