About Kvag

Kvag Ransomware stands for a cryptovirology PC threat used to blackmail its victims. Kvag Virus may not point to any evident symptoms, yet its presence is only discovered as soon as its job is performed.

Kvag Virus - crypted .kvag files

The absence of symptoms is one of the main difficulties with this sort of PC viruses. They can penetrate into the attacked system unnoticed, and implement their work without showing their activity in the workstation. This is why most customers are not able to do anything to terminate the virus before it has completed its mission, and the mission of this one, in particular, is to make its victims’ files unusable by means of data ciphering and then indicating a ransom demand.

The user is reported via a message that this infection puts on their screen that their only solution of bringing their data back is via the payment of a certain amount of funds. This blackmailing component of this scam is very popular among the frauds, and there’s a whole group of PC malware that’s used in this manner. This malware category is named Ransomware, and the malware we are currently concentrating on definitely falls under it.

The Kvag malware is only disclosed once it has completed encrypting the documents. The .kvag Ransomware will then express its demands by means of an intimidating pop-up alert.

It is via this alert that the users find out how they are expected to transfer their funds to the cyber frauds responsible for the Ransomware virus. In most instances, the ransom would be asked in a cryptocurrency – BitCoin. These cryptocurrencies are really hard to trace, and a typical user would have no chance of knowing who they are really transferring their funds to. This, in fact, makes it really unlikely that the hacker’s true identity would ever get disclosed. It is quite rare for a Ransomware hacker to stand before the court, and the application of cryptocurrency as the suggested payment solution is the main reason for that.

How to Kvag virus encrypt your files?

The .kvag Virus document encryption is not going to be eliminated after the ransomware is deleted. The .kvag Virus document encryption access key is promised to be given to you when you pay the ransom amount.

Nevertheless, it is not unusual for the hackers who stand behind such threats to promise their victims a decryption key for their encrypted documents only to refuse to provide that key as soon as the payment gets processed. Needless to mention, if you end up in a condition like this, you wouldn’t be capable of doing anything about it – your funds would be gone, and your data would still be inaccessible. This is why it isn’t really wise thought to transfer the payment, moreover, if you haven’t opted for any alternative options that may be effective.

Even though we mentioned that the encryption would remain on your documents even after the Ransomware is no longer in the system, deleting the virus is still extremely important. After you remove the Ransomware, you may also try the alternative file recovery solutions we have developed for you, and also your new files won’t be at risk of being encrypted.
