About the Masok Virus

Masok Virus

The Masok Virus will leave a ransom message with instructions in a _readme.txt file


The Internet is definitely among the biggest inventions of the human race. With that being said, it could also be something hazardous if you are not observant and cautious enough. One particularly dangerous type of malware which will be the focus of this article is what is known as Ransomware. The reason why this form of PC viruses are called Ransomware has to do with the fact they’re typically employed for blackmailing the web users into transferring a set amount of money to some anonymous online hackers. The cryptovirus we are going to be putting our emphasis on within the next paragraphs is one that’s well known for sealing the targeted user’s personal files by using a highly-advanced encryption code and afterward, demanding a ransom to be paid in exchange for the file-decryption key that can recover the data. The name of this particular virus that we’re referring to is Masok and in case you’re among the numerous unlucky victims of this dangerous infection, in the next lines, you will find some vital information that might help you deal with it and a special Masok removal guide.

Ransomware isn’t like any other malware on the web and operates quite differently than the majority of computer infections. Perhaps that’s the main reason this kind of insidious threats should be blamed for such a big number of hard-to-deal-with issues. Anti-malware programs are, most of the time, ineffective against Ransomware due to the ability of the malware to remain completely hidden. This is possible mostly due to the unique and uncommon behavior and methods, used by the infection. If malware like Masok, Prandel, Zatrov gets in your system, it will actually not aim to cause any destruction or harm to the computer or the files which are on it. That way, the cryptovirus will not trigger the virus definitions of the anti-virus program that you might have on your PC and will be able to remain unnoticed. The file encryption it uses to render your personal files inaccessible is, actually, a widely used file protection method, that does not damage anything and is usually non-harmful. Its idea is only to lock the target data and secure it with a special decryption key. Nevertheless, since you don’t have the key needed to decrypt your files, you will still be in trouble if they’ve been locked-up by Masok since you won’t be able to open or use them, even though they may still be stored on your computer.

The hackers, who stay behind Masok, will use that against you and will not hesitate to blackmail you in all possible ways in order to make you pay for the decryption key which is typically stored on their servers. The success of the Ransomware blackmailing method relies on the fear of the victims and their desperate attempts to regain access to their files.

If you want to tackle such a virus attack, however, it is necessary to get well aware of all the alternatives and the risks and try to explore other options instead of acting out of panic and giving the hackers the money they desire. In this way, you will have a chance to remove the nasty virus from your system and even restore some of your files from backups or by other means without risking your hard-earned money.
