Quimera virus Removal Guide
What is Quimera ransomware?
Quimera ransomware – a notorious malware form that does not mark the encrypted files
Quimera ransomware is a malicious infection that can infiltrate computer systems through email spam, software cracks, and unprotected RDP configuration
Quimera ransomware is recently discovered malware that locks files with a unique cipher but does not append an extension to the filenames. First spotted by S!Ri, this ransomware initiates the encryption process by running specific tasks via the Task Manager and targets all types of files and documents that are located on the infected Windows machine. Afterward, Quimera ransomware displays a ransom note named HELP_ME_RECOVER_MY_FILES.txt that urges for a 0.04 Bitcoin payment (around $300) in exchange for the decryption software. The crooks provide hyperlinks where the victims can buy Bitcoin cryptocurrency and also include their email@example.com email address. These people offer users to deliver them any type of file for free decryption and they will prove that the decryption tool works.
|Founder||This malicious infection has been first discovered by a cybersecurity researcher named S!Ri|
|Encryption||The ransomware virus locks up various files and documents that are found on the infected Windows computer by using a unique encryption cipher. However, the malware, unlikely from others, does not add any type of appendix to the names of encrypted files|
|Ransom note||All of the ransom demands and contact information is provided in the HELP_ME_RECOVER_MY_FILES.txt ransom message|
|Price||The criminals demand a payment of 0.04 Bitcoin that is approximately $300|
|Email address||The malicious actors provide the firstname.lastname@example.org email address as a way to contact them. The victims are offered to send one file for free decryption and also deliver the evidence of the payment later on|
|Spreading||Phishing email messages and their malicious attachments are the most popular ransomware distribution source. However, this malware can also get delivered through software cracks, unsecured RDP configuration, etc.|
|Removal||Get rid of the ransomware as soon as you spot the first symptoms. For this purpose, use reliable antimalware software only|
|Fixing tool||If you have discovered any type of system compromisation on your Windows machine, you can try using a repair tool such as ReimageIntego|
Quimera ransomware includes malicious modules into the Windows Task Manager and injects entries into the Windows Registry. This way the malware can enable some features such as automatic boot up every time the computer is turned on. Regarding this task, the cybercriminals will be sure that their ransomware is active all the time when the PC is alive.
Continuously, Quimera virus might try to evade antimalware detection. As a result, some software might not be able to detect this ransomware, unless the victim reboots his/her Windows computer in Safe Mode with Networking or System Restore. If you are also struggling with this, travel to the end of this article and you will find some instructing steps.
Quimera ransomware is a dangerous virus that urges a 0.04 Bitcoin payment in exchange for the decryption key
However, according to VirusTotal information, 44 AV engines out of the total 69 detect Quimera ransomware as a malicious threat. Some of the detection names include Win32:MalwareX-gen [Trj], Malware@#1ndvs5ku238ur, Gen:Variant.Ulise.94720 (B), Ransom.Quimera, Gen:NN.ZexaF.33564.EuW@aO93MKgi, Artemis!757FE364CEF1.
Quimera ransomware might also run specific PowerShell commands that allow deleting the Shadow Volume Copies of all encrypted files. By performing this type of process, the cybercriminals seek to harden the decryption process for the victims who might try recovering some of their documents by using alternative software.
Quimera ransomware developers store both encryption and decryption keys on remote servers so that the codes would be reachable for the cybercriminals only. However, this is not a reason to purchase the decryption tool from the crooks. Even though it might be hard to recover data on your own, paying the crooks might end up in getting scammed.
Additionally, Quimera ransomware might not be the only malware that lands on your computer system. This cyber threat might be packed with other dangerous viruses such as trojans that aim to steal personal information, swindle money from the user's bank account, destroy particular programs, eat up the CPU power, and slow down the entire computer system.

Phishing techniques are used for ransomware distribution
Technology specialists from NoVirus.uk claim that ransomware infections are commonly spread via phishing emails and their malicious attachments such as pdf documents, executables, word files, etc. The crooks often pretend to be from reputable shipping, banking, or healthcare companies and deliver the infection inserted in a hyperlink in the message or in the attachment that comes clipped to the email.
If you are thinking about how to avoid infectious through these types of sources, we recommend managing your email carefully. You should always check the sender and the message's content for grammar mistakes. Also, if you were not expecting to receive the email message, you can surely delete it as any official firm would also contact you via mobile phone. Besides, do not open any attachments without scanning them automatically.
Continuously, ransomware viruses can spread through cracked software that is placed on secondary downloading networks such as The Pirate Bay. These sources come unprotected and can easily carry malware. Also, the virus can be distributed through an unsecured RDP configuration. The hackers find it very easy to connect to the targeted system remotely if the RDP includes weak passwords or is not protected with a password at all.

How to prevent from getting ransomware
Protect your privacy – employ a VPN
There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals.
No backups? No problem. Use a data recovery tool
If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.
If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
