Cryptobyte File Virus Removal


In the article below we will be talking about the malware identified as Ransomware. You should know that these viruses actually represent the most frightening cyber threats, which you could ever come to face at the present moment. Such programs can sneak into your computer, thoroughly review all its drives (and other storage), and define which data exactly you happen to access and use on a regular basis. As a result, all of the predetermined files can end up encoded. After that, a ransom is going to be demanded from you in exchange of your encrypted data. This awfully bothering description also applies to Cryptobyte File Virus – the exact virus we are reviewing in the following text.

Generally speaking about Ransomware:

Ransomware is the name of all the harmful programs, famous for their encryption activities – either of your desktop/screen, or of your data. Despite the fact that the particular Ransomware programs you might face may be after various aspects of your PC, they have some common features. Such a virus could infect your computer on its own, mainly automatically, which means that once you happen to visit/use any of its sources, such a malicious program may subtly sneak into your system, and do whatever it has been programmed to. Later on, the typical course of events continues in this way: the encryption process is complete and a ransom payment is demanded from you in exchange for “restoring” your access to your desktop/screen or files.

Ransomware Subtypes

In fact, Ransomware can be divided into some subgroups and not all of them will affect one and the same component of your system. That’s why we will enlist the most usual subtypes in order to give you a clue about the infection you may be facing:

  • Ransomware programs, which target the desktops of your PCs:
    Such malicious programs can only attack the desktops of your computers (and laptops as well). Actually, nothing harmful will happen to your files. However, such a virus will display a whole-screen alert, which will render you unable to access anything behind it. Normally, such an alert can comprise the ransom demands, as well as some payment details.
  • Ransomware which infects mobile (portable) devices:
    Such viruses will only infect smartphones, tablets and other mobile devices such as phablets, for example. They behave in a way that resembles the way the desktop-locking viruses do. What actually happens is that such a virus limits your access to the display of the targeted mobile device by showing a ransom-requesting alert, which covers the whole mobile-device screen. Such an alert will inform you about the ongoing infection, and will demand your money in exchange for unblocking your displays.
  • The most popular subcategory: the Ransomware viruses targeting data:
    In fact, this is the subgroup Cryptobyte File Virus  is a member of,  and represents the most famous Ransomware category.  What such a virus could do is to sneak into your PC, define which files are most valuable to you and encrypts these files exactly. Later in the process, you will be harassed into paying an amount of money as a ransom for the decryption of your important data. To be honest, this is the most terrible type of Ransomware, as some vital information may be affected and you may never be able to recover it.

Potential sources of viruses like Cryptobyte File Virus:

If you haven’t heard of any possible Ransomware sources, we can tell you that an infection may come from different places and various content on the Internet. For your information, we will mention the most usual sources here:

  • Shareware and torrents could include such malware;
  • Cryptobyte File Virus might also be found incorporated into some contagious websites (when you visit such a page, this virus could come as a drive-by download to your system);
  • Such a Ransomware program may be hiding inside a letter or any of its attachments inside your email. If this is your scenario, it’s usually distributed along with a Trojan horse virus, whose exact purpose is to determine how your system is most likely to get hacked, and to sneak a program like Cryptobyte File Virus inside it, usually through a program/system weakness;
  • The biggest number of all infections has actually occurred because the victim user has followed a fake online ad like a pop-up or a banner.

Some working solutions in case of an ongoing infection:

  • First of all, don’t go and pay the hackers immediately after they have requested the ransom. To our great disappointment, doing so will not guarantee you the successful decryption of your locked-up data.
  • Secondly, go and see a professional for some valuable advice. Some experts could have some more experience getting rid of such threats, which could really be useful.
  • Last but not least, you could also try to deal with this virus with the help of a Removal Guide (check the one we have designed below).

Cryptobyte File Virus Removal

Prior to starting to execute the steps from the guide, we advise you to either bookmark this page or open it on a separate device since throughout the process of completing the guide, you might need to exit your browser.

1: Using Safe Mode

Before beginning to troubleshoot the issue, you are advised to enter Safe Mode on your PC. If you do not know how to do that, use this guide on how to enter Safe Mode.

2: Spotting the process

Open your Task Manager using the Ctrl + Shift + Esc key combination. Next, go to the processes tab and carefully look through the list for any shady entries. Usually, malicious processes will be consuming large amounts of CPU and RAM and will either have no description or will have a suspicious-looking one.

Once you identify the virus’ process, right-click on it and select Open File Location. Delete everything in the folder that opens if you are sure that the process was malicious. If you are not sure, contact us in the comments.

Go back to the Task Manager and end the potentially harmful process.

3: Hosts file IP’s

Go to your start menu and in the search field, paste the following address: notepad %windir%/system32/Drivers/etc/hosts. Select the first result and look at the bottom of the newly opened notepad file. See if there are any IP’s below “Localhost” and tell us in the comments if there were any IP addresses. 

4: System Configuration Startup Programs

Type System Configuration in the Windows search bar and open the first result. Go to the Startup tab and take a look at the list of startup programs (on Windows 10, the Startup programs can be seen in the Startup Section of the Task Manager). If any of them look shady or have unknown manufacturer or a manufacturer with a sketchy name, uncheck those entries and click on OK.

5: Registry

Open the Run window (WinKey + R), type regedit and press Enter. Once the Registry Editor opens, press Ctrl + F and type the name of the virus. Select Find Next and delete whatever gets found that has the virus’ name. Do that with all search results.

6: Deleting potential virus files

Open the Start Menu and separately type each of the following locations: %AppData% %LocalAppData% %ProgramData% %WinDir% %Temp% . Open each of those folders and sort their contents by date. Delete the most recent files and folders. When you open the Temp folder, delete everything in it.
