What is UserFilesLocker ransomware virus?

How destructive is UserFilesLocker ransomware?

UserFilesLocker virus, alternatively known as FileLocker, presents itself as a file-encrypting ransomware[1] targeting Czech and Slovak users. Interestingly, that supposedly Czech cyber villains are on the move since it is already a third virus introduced in this language. Do not underestimate this malware, but instead focus on UserFilesLocker removal. It is known that the malware encrypts the files with AES-256 and RSA-2048 key and then appends .ENCR file extension. This technique results in the complex encrypting key[2]. The most viable ways to decrypt it is to obtain the official decryptor or use backup copies. If you do not own either of them, take a look at the data recovery recommendations displayed below the article. Keep in mind that data recovery is effective only when you remove UserFilesLocker fully. In this regard, let FortectIntego deal with the infection.

Looking from a technical perspective, UserFilesLocker ransomware does not differ much from other crypto-malware. In the beginning of the ransom message, it scares users with the fact that their data has been encoded with a complex, military-level encryption algorithm. It ensures that there is no other way to recover the files other than complying with their demands and paying the ransom. In exchange for the key, they ask 0,8 bitcoin (955,18 USD)[3].

The picture displaying UserFilesLockerUserFilesLocker virus, or alternatively known as FileLocker, contains similar elements to recently emerged Spora malware.

Interestingly, that it offers another variation of the payment – 2,1 BTC. However, no specific information is provided about the conditions of paying their amount of money. Moving on, the cyber villains of User Files Locker seem to sympathize with the creators of Spora ransomware which delivers sophisticated customer service[4]. Likewise, the creators of FileLocker also present a step-by-step payment program for receiving the payment. They ensure fast data decryption to please their “customers”, i.e, victims. It also provides the email address – – in case the victims encounter any payment trouble. Needless to say, that such mocking manner of speech should not encourage you paying the money. The key reason of booming ransomware business is victims’ hope to retrieve the files. Nonetheless, there are few data retrieval cases. Instead, remove UserFilesLocker right away.

The transmission tendencies of the malware

Unlike other prominent file-encrypting threats, UserFilesLocker hijack occurs upon visiting the corrupted Czech and Slovak sites. Specifically, exploit kits serve as temporal carriers for this threat. EITest malicious code may as well contribute to the attack. Upon visiting them, the malware connects to the following web pages:,, and The felons may as well target the victims via spam messages. They try to scare with fake notifications from the Supreme Court or the FBI. The binaries of UserFilesLocker malware may hide in the invoice attachments or .zip folder which contains the following elements: prehled_hotely.exe, installer.exe, elektronicka-komunikacia-instalacia.exe, and encrypt.pinfo. The latter file contains encryption information[5]. It is of crucial importance to keep your system applications updated to reduce the general number of vulnerabilities on your system.

How to prevent from getting ransomware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
