Losers virus Removal Guide
What is Losers ransomware virus?
Losers ransomware might lock files with .losers or .wtf extensions
Losers virus is a file-encrypting virus that emerged in October 2017 and mostly targeted Indonesian computer users. Back then the virus appended .losers file extension to make files impossible to open. However, in December, developers presented a new version of malware which uses .wtf extension.
Losers ransomware seems to belong to Cry36 ransomware family. Malware executable has been noticed spreading via free DVD burning software called Burn4Free. Once inside, it starts data encryption procedure and delivers HOWTODECRYPTFILES.txt file which warns about ransomware attack:
the ALL YOUR WORK the AND the PERSONAL FILES HAVE to the BEEN The ENCRYPTED
Losers ransomware ransomware
the To decrypt the files is your Up Need you to the buy the special software – «Losers decryptor»
the To recover data, follow the instructions!
Crooks provide a detailed explanation how to use Tor network, obtain Bitcoins and transfer them to the criminals. Nevertheless, the ransom note does not provide the exact price of the ransom; victims claim that it asks for $500.
However, paying the ransom might lead to money loss. Cybercriminals are not reliable people, and they might not have working decryption tool. Even if they have it, there’s no guarantee that they will keep their promise and let it use it once you make the payment in Bitcoins. Thus, we highly recommend Losers ransomware removal instead of accepting shady criminals’ offer.
Unfortunately, malware elimination will not help you to get back your files. However, once you remove Losers malware with the help of RestoroIntego or another security software, you will be able to restore your files from backups or try alternative recovery methods.
New version of Losers ransomware was released in December 2017
In December 2017, malware researchers detected a new variant of Losers virus is spreading on the web. Cyber criminals named it as Dangerous ransomware. However, security experts call it Losers-Dangerous ransomware or simply Losers-2.
The malicious program uses AES cryptography and adds .wtf file extension. Following the encryption, it drops a new ransom note in HOWTODECRYPTFILES.html file. Here criminals inform that victims have to obtain Dangerous decryptor in order to restore their files. They did not provide the price but left a contact email address firstname.lastname@example.org for those who are interested in this shady deal.
Currently, both versions of the virus are not decryptable. However, security experts do not recommend paying the ransom. No one can guarantee that it will help to bring back access to your files. Once you make a transaction, criminals might disappear or ask for more money. Thus, we highly recommend Dangerous ransomware removal with reputable antivirus.
After the attack, Losers ransomware virus appends .losers file extension to the targeted images, audio, video, and other files.
Learn how to protect your PC from malware
Users report that suspicious activities on their computers started after installing the Burn4Free program that allows burning DVDs. The program brings lots of crapware to the device, including Losers. Therefore, users are advised to be careful with freeware downloads. Always use reliable download source and monitor installation process in order to reject installation of “optional downloads.”
However, hackers rarely rely on only one distribution method. Therefore, you should also be aware that malware might infiltrate the system when you:
- open malicious email attachment;
- download illegal software, movies, music or other content;
- click on a malware-laden ad;
- keep software or operating system outdated;
- download updates or programs from pop-ups.
Therefore, in order to avoid ransomware viruses in general, you have to watch your steps and clicks. Keep in mind that criminals have great social engineering skills. Therefore, malicious email attachments might look like legit documents sent from a well-known company. Hackers might also use the name of credible developers or apps and spread malicious entries on torrents, P2P networks and similar file-sharing sites.
However, in order to strengthen your computer’s security, you should also invest in reputable antivirus software. It’s also important to update it regularly to minimize the risk of the attack. Though, security software is not almighty. Malware might still infiltrate the device if you do not be careful. Thus it’s better to have backups.

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.
