Qqlc

Qqlc is a malicious PC virus that falls under the infamous Ransomware category. Viruses like Qqlc are capable of blackmailing their victims by locking their data or their whole computer and demanding a ransom payment if the user wants to bring things back to normal.

Stop Virus 1024x550

The method used by Qqlc and Qqlo in order to render the user’s personal files inaccessible is what is known as encryption. Once the malicious program gets inside the PC, it encrypts the user’s personal files and the only way to open them after that is to have a specific encryption key. Normally, once all targeted data has been locked by the Ransomware, a message is displayed on the PC screen which contains detailed instructions on exactly how to make the money transfer. In most cases, the ransom is demanded in the form of bitcoins which the user first needs to purchase and then send to the hacker. This allows the latter to remain fully anonymous. Because of that, seldom do hackers who use Ransomware get caught and brought to justice – something you should keep in mind.

Here, we will attempt to acquaint our users with the most characteristic traits of Qqlc and Ransomware viruses in general so that they are able to provide their computers and files with better protection against this type of malicious software. As for those of you, who have already had their system invaded by Qqlc and their files locked by its encryption code, we have prepared a free Ransomware removal guide that you can find down below.

The Qqlc virus

The Qqlc virus is a variation of the file-encrypting Ransomware type of computer viruses. The Qqlc virus has the purpose of locking your data with the help of an elaborate encryption algorithm and then forcing you to pay money to its creators for the files’ access.

Not all Ransomware viruses use the same method in order to blackmail their victims. For instance, there is a type of Ransomware that, instead of locking the user files one by one, directly blocks the access to the computer by covering its screen with a large banner or image, which prevents the user from interacting with their PC. Its a simple but effective method since the said banner/image would cover everything else – programs, files, folders, the Task Manager and the Start Menu would all get covered by the intrusive image which would remain there either until the ransom is paid or the user finds a way to get rid of the virus.

The other most widely-spread variation of Ransomware is the so-called cryptovirus, which is also what Qqlc is. Normally, this type is more advanced than the non-encrypting Ransomware. One of the major issues with cryptoviruses is the fact that removing the infection would not restore the access to files that have already been encrypted by the nasty malware.

The Qqlc file decryption

The Qqlc file decryption is the process you must complete in order to unblock the inaccessible data on your PC. To complete the Qqlc file decryption, you will need to obtain a special key that only the hackers possess at the moment of the encryption.

Qqlc File

Decryption/file restoration is actually the most difficult part when it comes to handling a Ransomware infection. A major problem with this is the uncertainty with regard to whether or not paying the ransom would actually get you the key. There’s some light at the end of the tunnel, though, in the form of the removal guide we will provide you with below. After the removal instructions, you will also find some steps that may provide you with options on how to potentially bring some of the files back without needing to risk your money by paying a ransom.

Remove Qqlc Ransomware


Step1

If you want to properly get rid of Qqlc, one of the first things you should do is to disconnect your computer from the Internet. The next step is to unplug any USB drives or other external storage devices from the infected computer. Once this is done, we recommend that you restart your computer in Safe Mode by using the instructions on this page.

After the Safe Mode restart has been completed, you should navigate back to this page (it is a good idea to bookmark it right now in order to return to it later) and continue with the instructions described in step 2.

In the second step, open the Task Manager application by simultaneously pressing the Ctrl, Shift, and ESC buttons on your keyboard. After that, in the window for the Task Manager, choose the Processes tab from the top tabs, and then browse the list of processes while keeping an eye out for any processes whose names are strange. Also, note how much CPU and memory each process is using and if you find a process that is consuming an abnormally high amount of resources for no apparent reason, research it on the internet.

A quick way to check the files of a suspicious process for malware is by right-clicking on the process and choosing the Open File Location option.

    If you find anything suspicious in the files that have been scanned, you need to go to the Processes tab and terminate the process that is connected to those files as soon as possible. Simply right-click on the process you want to terminate, and when the context menu appears, choose End Process from the list. After that, any files that the scanner identifies as potentially harmful should be removed from the file location where they are stored.

    Step3

    In the third step, you need to check that your Hosts file has not been changed without your knowledge. To do that, open a Run box by simultaneously pressing the Windows key and the letter R from the keyboard, then paste the following command in the Run box and hit the Enter key.

    notepad %windir%/system32/Drivers/etc/hosts

    In the Hosts file, search for IP addresses that are listed under Localhost but do not seem to be reliable. If you see IP addresses that appear fishy, please let us know about them in the comments below so that we can have a look at them and provide you with guidance on what to do if we find anything odd about them.

    The System Configuration window is the next place of the system that requires your attention. You may open it by going to the Windows search bar, typing “msconfig“, and then pressing the Enter key on your keyboard. After that, choose the “startup” tab in order to examine the components that are loaded during system boot time. If you have any reason to assume that a startup item is related to the ransomware that you want to remove, then you should remove the checkmark from that item. Clicking the “OK” button will save your modifications in the end.

    In order to eliminate all traces of Qqlc from the system, it is required to do a thorough scan of the Registry. If you don’t know how to search in the Registry in a way that is both efficient and uncomplicated, then open the Registry Editor, by going to the Windows search box, typing regedit, and then pressing the Enter key on your keyboard.

    After the Registry Editor opens, press Control and the F key from the keyboard at the same time to open a Find box. The next step is to search for files that are related with the ransomware using this Find box. Once you’ve entered the name of the ransomware in it, you may click on the Find Next button.

    Attention! It’s possible that removing files from the registry or making other changes there may result in serious problems in the operating system. Because of this, we highly recommend that you use the professional malware removal tool that is linked on our website in order to delete any Qqlc-related files that are hidden in the registry. It is unadvisable to delete registry entries without having the necessary knowledge and experience.

    After the registry search shown no files linked to the ransomware, you may safely close the Registry Editor.

    For a more thorough check, we also recommend you to search for ransomware-related files in the locations specified below. Use the search bar on Windows to paste each of the search words, and then open them one at a time by pressing Enter.

    1. %AppData%
    2. %LocalAppData%
    3. %ProgramData%
    4. %WinDir%
    5. %Temp%

    You need to check for files that might be dangerous, but you shouldn’t remove anything unless you are very convinced that it represents a risk. You may delete the temporary files from the system without causing any harm to it by choosing everything in the Temp folder first, and then clicking the Delete key on your keyboard.

    Step5

    How to Decrypt Qqlc files

    The process of decrypting data that has been encrypted by ransomware may be a tough task for inexperienced users. This is owing to the fact that the decryption methods that may be applied may differ depending on the variant of ransomware that has infected your system. If you want to figure out what variant of ransomware you are dealing with, one smart place to start is by looking at the file extensions of the files that have been encrypted on your computer.

    It is essential to carry out a malware check on the infected machine with a sophisticated anti-virus application, such as the one that can be found on our website, before initiating any data recovery procedure. It is not recommended that you attempt any techniques of file recovery before the computer has been thoroughly scanned for malware and it has been shown that there are no threats present on the system. Skipping this system scan may cause even more harm and loss of data.

    New Djvu Ransomware

    STOP Djvu is a new ransomware threat tha adds the .Qqlc extension to the files that it encrypted. Not everything is hopeless if you have lost access to your data as a result of the Qqlc encryption, tough. You can still try to recover some of the encrypted files by using decryptors such as the one that can be found on the following website.

    https://www.emsisoft.com/ransomware-decryption-tools/stop-djvu

    To use the decryptor, download the STOPDjvu executable file from the link above and agree to the license and the additional instructions of use. Please understand that even though this program is a powerful decryptor, it is possible that it may be unable to decode data that has been encrypted online or by using unknown offline keys. Despite this, we strongly recommend that you give it a go, and that you under never circumstances whatsoever pay the ransom that has been asked.

    To ensure that Qqlc has been removed successfully, you can run a full system scan with the professional malware removal tool linked on this page. Another tool that you can use to scan specific files that look questionable is the free online virus scanner from the link.
