UselessFiles virus Removal Guide
What is UselessFiles ransomware?
UselessFiles ransomware is cryptovirus that was discovered by security experts in early May 2018
UselessFiles ransomware is a file-locking virus that was given an ironic name as it encrypts all files on targeted PC by adding .uselessfiles extension. For that, the malware uses a complicated encryption algorithm that can only be decrypted using a special key stored by hackers. As soon as files are encrypted, ransomware virus executes a program which displays ransom note called “UselessFiles!.” For unlocking affected data, cybercriminals are demanding $300 in Bitcoin. We highly recommend ignoring these demands.
|First spotted||May 1st 2018|
|Demanded ransom||$300 in BTC|
|Distribution||Spam emails, malicious websites, etc.|
|Elimination||Download and install ReimageIntego or SpyHunter 5Combo Cleaner|
UselessFiles ransomware typically enters victims’ machines using deceptive ways, for example, via the contaminated attachment in a spam email. Other distribution methods include:
- hacked or malicious websites;
- unprotected RDP configuration;
- exploit kits;
- fraudulent downloads, such as fake updates;
- infected installers;
- repacked software or key generators, etc.
Regardless how the malicious payload entered your machine, the first thing that needs to be done is UselessFiles ransomware removal. For that, security experts advise using a robust security program, such as ReimageIntego or SpyHunter 5Combo Cleaner. In case malware does not let anti-virus application to start properly, you should reboot your PC in Safe Mode with Networking.
UselessFiles virus blocks a variety of personal files, including .doc, .html, .gif, .jpg, .mp3, .mpeg, .txt, .xlsx, etc. For example, if you had a file called picture.jpg, it will be turned into picture.jpg.UselessFiles after the attack. From that point of time, all files with such appendix become unusable. To return files, victims must pay a ransom of $300 in Bitcoin into the provided address.
Hackers explain that, as soon as the payment is processed, victims can start file decryption procedure. They also note that if security software removes the program, users will not ever be able to return their data.
Nevertheless, security experts highly discourage users contacting the authors of UselessFiles as there is no guarantee that they will provide a working key. There is a possibility that hackers might send malware instead of decryptor and damage the machine even more. Additionally, with successful attacks, cyber crooks will be encouraged to create more file locking viruses which allow them to benefit financially.
Unfortunately, the only guaranteed way to return your data is by getting it back from a backup, such as a cloud server or an external HDD. Thus, if you have a backup – you will get all your data back safely. If not, you can also try few third-party programs that could help you. But first, you have to remove UselessFiles ransomware from your machine. You can find all the instructions below.

However, if you are careless while browsing the internet, the chances increase by a significant margin. Thus, we advise users to take these precaution procedures:
- never open all the emails from unknown sources. The main danger lies in malicious file attachments (which might seem legitimate at the start) or links that might appear like they are leading to a genuine website (such as Amazon, Dropbox and similar);
- always keep your operating system and software up to date as its developers continuously release patches to fix vulnerabilities within their programs;
- avoid visiting suspicious websites, such as porn, gambling, free online gaming, etc.;
- do not download repacked or illegal software as malware authors often inject these installers with malicious code;
- keep a regular backup of your files;
- employ a reputable security program and keep it up to date.

If your files are encrypted by UselessFiles, you can use several methods to restore them:
Try Data Recovery Pro
This software was designed to bring back files that we accidentally deleted or damaged in other ways. In some cases, Data Recovery Pro is known to help users whose data was encrypted by ransomware.
- Download Data Recovery Pro;
- Follow the steps of Data Recovery Setup and install the program on your computer;
- Launch it and scan your computer for files encrypted by UselessFiles ransomware;
- Restore them.
Windows Previous Versions feature might be useful
Windows Previous Versions feature will only work if you had System Restore function enabled:
- Find an encrypted file you need to restore and right-click on it;
- Select “Properties” and go to “Previous versions” tab;
- Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.
ShadowExplorer might recover all your files

No decryptor is available yet
Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from UselessFiles and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes
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.
