As mentioned above, you will find the “_readme.txt” ransom note on your PC. It says that all your files are encrypted and you need a private decryption key to unlock those files. The note contains instructions to contact attackers to buy the decryption tool. This nasty Efvc Virus infection will demand ransom money through Bitcoin because it cannot be traced.

This nasty Efvc Ransomware is a really serious threat to your PC. It can corrupt all your system files and make you unable to access your data. This dubious threat will not allow you to even open your files. It will strictly prohibit any kind of access to encrypted data. If you will move your data to any external storage device still then you will get only the encrypted copy of your files. You will also not be able to access those data on any other computer.

It can also infect the other computer that you will use to access your encrypted data. So don’t try to play games with Efvc Virus. It can cost you much more. Also, take your infected PC offline immediately to protect other devices on your network. It is also not suggested to pay ransom money because it will not decrypt your files.

How does it infect your PC?

Efvc File Virus can spread in different ways. It is hard to determine how it got on your system specifically. Cybercriminals mostly use software bundling and spam email campaigns to deliver such threats. When you download any freeware application from shady websites, they might carry malicious attachments. Use the custom installation process and read EULA carefully to avoid the installation of hidden programs. Do not open spam emails from unknown senders and do not click on any link or open attachments without scanning.

Apart from this, Efvc Virus can also get on your system through browsing porn or torrent sites. These kinds of sites cause unwanted and forced redirection of browsers on phishing websites. Those sites most likely host malicious scripts that trigger automatic malware downloads. Sites asking for cookie permission to show pop-up notifications can also do the same.

Downloading pirated or cracked software and games can also bring threats like Efvc Virus on your PC. These kinds of programs are created by using hack tools, a type of Trojan infection that can be used to deliver threats on the host computer. Installing illegal patches and fake software updates, sharing files on unsafe websites, and using an infected USB drive can bring this virus to your system.

Is my PC infected by Efvc Virus?

If you are unable to open your files, documents, images, videos, etc. on your PC because they have a “.Efvc” extension, then Yes, your computer is infected. These kinds of crypto-virus mainly get installed on the targeted PC through unknown installers and encrypt all the files. In the case of Efvc File Virus infection, you will find no symptoms of infection until all your files and locked.

This nasty virus scans the entire hard drive for files and then use its powerful AES/RSA encryption algorithm to encrypt files.

Efvc Ransomware uses a very powerful encryption algorithm to encrypt your files. There is no way to break the encryption without the decryption key. Unfortunately, there is no free decryptor available for this infection even though it has been terrorizing innocent victims for a while now. Due to frequent changes to the ransomware variants, security researchers have not been able to develop any free decryptor.

Efvc File Virus infection is quite cunning and its ruse is also very good. It is offering a 50% discount on the ransom fee if victims pay under 72 hours. The original price of the decryptor is $980 in Bitcoin, but one can purchase it for $490 if they within 3 days. This nasty virus is also offering decryption of 1 file for free as proof.
