.Berost Removal guide for windows and mac
These are the infected files by a new strain of the STOP Ransomware, modifying the extension with .Berost

If you get infected with a Ransomware threat such as .Berost, you normally won’t get to know about it until a shocking ransom-demanding notification gets displayed on your screen. Those pieces of malware don’t typically trigger any visible symptoms of their presence until they complete their agenda and oftentimes manage to remain under the radar of the security program of the user because they don’t really cause direct damage to the system or to its software. This is exactly what makes the Ransomware infections so difficult to detect and remove.

In addition to this, the .berost ransomware could also infect your computer by having the infection files uploaded on suspicious sites. The infection files could pretend to be cracks, patches and other forms of activators.

Once .Berost file ransomware has infected your computer, the virus may immediately drop the malicious files in the following directories:

%AppData%

%Local%

%LocalLow%

%Roaming%

%Temp%

For many web users all around the web as well as for different businesses, institutions and organizations, infections like .Berost,  .Fedasot.Dutan.Roldat have become a synonym for disaster because, once a malware of this type finds its way into the computer, it immediately starts to secretly apply a complex file-encryption code to all the files that are stored on the HDD. The targeted information may comprise documents, different personal files, archives, audios, images, videos and other commonly used data which becomes totally inaccessible the very moment an encryption code is applied. A scary ransom-demanding message typically gets generated on the screen after the attack and in it, the hackers behind the malware infection demand that their victims pay a certain amount of money (usually in BitCoins) if the latter want to regain their access to the encrypted files. In exchange for the payment, they are promised to obtain a unique decryption key which is the only thing that can reverse the complex encryption code that has been applied by the Ransomware.

The blackmailing scheme relies on surprising the users and giving them a very short deadline to transfer the money. Various tactics of harassment are used to help the hackers in their money-extortion, including threats, psychological pressure and fake promises. The people who don’t keep important data on their computer may not get impressed by such shenanigans but those who have had their valuable information captured by the encryption of a threat like .Berost may have a real hard time dealing with the consequences of the attack.

A common tactic that a lot of cyber criminals use is to pretend that they want to “help” the users. They may even go as far as offer to decrypt a file or two before the ransom is paid in order to gain the trust of the victims and convince them that they have the solution for the salvation of their files. All the hackers want in return is that the user strictly follows the payment instructions.

An alternative to consider

Opting for the payment “solution”, however, hides a lot of risks and can never give you any guarantees about the future of your computer and the data that is stored on it. That’s why our suggestion for the victims of infections like .Berost is to not trust the crooks. Instead, we recommend you explore other options that don’t involve giving your money to criminals and which can help you remove the malware from your system.
