Qbaa Virus (.Qbaa) File Removal Guide

Qbaa virus is a variant of the notorious STOP/Djvu Ransomware family. This dubious file-encrypting malware has the ability to encrypt all the files on your PC. It appends the “.qbaa” extension after rendering your files useless and creates a “_readme.txt” ransom note.

Qbaa Virus

Qbaa virus renames files to mark them encrypted. For example, a file named “sample.jpg” will appear as “sample.jpg.qbaa”.  Victims will need decryption tools along with private keys to regain access to such files. Cybercriminals demand huge ransom money in BitCoin (cryptocurrency) to provide those tools.

After Qbaa File Virus attack, victims cannot access their documents, pictures, videos, audio, archives, databases, backups, and more. So users are being forced to deal with attackers and pay them. This guide is aimed to help you remove Qbaa virus and restore your files without paying money to ransomware creators.

What is .Qbaa File Virus

Qbaa Ransomware is a dangerous threat that blackmails innocent users by taking their files hostage. It uses a powerful encryption algorithm to restrict access to your personal data. As mentioned above, it is a part of STOP/Djvu family and unfortunately, it is not decryptable. Victims are advised to remove the infection and explore data recovery alternatives other than paying ransom fees.

Creators of this threat advise victims to purchase the decryption tool and unique key. They launch a new variant almost every week, making it difficult to find a permanent solution. It will keep encrypting new files until you remove this threat completely from your PC. Removing this threat will not restore your files, but it will prevent further damage. You cannot recover data from backup until you get rid of this infection.

How does Qbaa Ransomware spread?

Creators of threats like Qbaa Virus use various methods to spread their creation. Spam emails are one of the most used methods to target innocent users. Emails containing malicious attachments and links are used as carriers to distribute harmful threats. When you get an email from an unknown person or organization that carries some attachments, do not open them.  Do not click on links without verifying the sender and always scan attached files before opening.

Qbaa File Virus can also get distributed via bundled freeware downloads and Peer-to-Peer sharing networks. Cracked software or illegal patches (activation tools) and fake software updates are also used to spread infections. Visiting porn or torrent sites can also expose your system to lots of unwanted threats and viruses.

Do Not Pay Ransom to Qbaa Virus

The note left by the Qbaa Ransomware says that the price of decryptor is set to $980 USD in Bitcoins. But there is bait too. Virus creators are offering a 50% discount to victims who are willing to pay under 72 hours. So if the user agrees to pay during the first 72 hours of the infection, the ransom fee will be $490USD.

It is a trick used by cybercriminals to force their victims to pay money quickly without seeking advice from anyone else. In most cases, it is hard to restore files without a decryption key but it is also not guaranteed that you will get that after paying.

We advise our readers not to trust the attackers. It is all a scam and they are only interested in money. You cannot trace Bitcoin payments and it is also not reversible. So in case of fraud, you will lose both your money and the data.  Stop/Djvu variants are also known to leave Trojans behind to steal users’ personal and financial information. It is also used to open backdoors through which the next variant can attack your PC again.
