A Ransomware virus is a piece of malicious and dangerous software that cyber-criminals typically use for money extortion through blackmailing. The main purpose of the virus itself is to either lock the files of the targeted victim or their whole device (a PC, a laptop, a smartphone, a tablet, etc.). Once the device or the files have been sealed and are no longer accessible, the user is required to make a ransom payment to the hacker who has infiltrated their system. If the money isn’t paid, the device or the data on it would remain inaccessible and the user wouldn’t be able to use them. In the next lines, our focus will be targeted on a recently released cryptovirus program. The cryptoviruses are one of the main Ransomware subcategories.
This particular Ransomware sub-type is known for its ability to use encryption on the files of the user, thus rendering them inaccessible for anyone who doesn’t have a special key for decrypting them. As you might have already guessed, only the hackers behind such a malware attack would normally have possession of the decryption key and in order to recover their data, the virus’ victims are supposed to pay for it. The name of the cryptovirus that we are going to be focusing on throughout the following few paragraphs is .Promos and it is one of the newest representatives of the Ransomware malware category. In case you have already gotten attacked by this insidious software threat, it would be in your best interest to stay with us throughout the remainder of this article in order to learn more about Ransomware viruses and about .Promos so that you know what your potential options currently are and also so that you’d be able to keep your system safe and clean in future.
About Ransomware cryptoviruses
As mentioned in the introduction, the cryptovirus Ransomware sub-category is considered to be the nastiest and the most problematic of all other forms of Ransomware infections. The key factor that makes this particular kind of illegal programs so devastating is the encryption they use when locking the targeted user files. In most cases, there are no symptoms to suggest that there’s anything wrong going on inside the PC. A typical encryption process wouldn’t really cause direct damage to any of the files on your machine or to the computer itself. Sure, the data does get sealed and is rendered inaccessible after the encryption has been completed but this doesn’t mean that the files themselves have been damaged. Quite the opposite – any data that gets encrypted is secured against unauthorized access and cannot be used or modified without the decryption key. In fact, encryption isn’t an inherently malicious process, it is actually an advanced method used for data protection of important and valuable files and many software developers make use of it on a regular basis to protect their data and documents. Of course, in the case of a Ransomware cryptovirus attack, all of this gets turned upside down as the owner of the files is actually the person they are “protected” against. However, what’s important about all that, the reason why it matters, is the fact that due to the overall lack of damage and harmful effects, there are typically no red flags that would signify ad indicate the presence of the malware. Even reliable, high-quality antivirus programs might oftentimes fail to spot a potential Ransomware infection because of this same reason. In some instances, if the user is attentive enough they might be able to notice that their machine is using more RAM and CPU than it is supposed to and upon further investigation they might find and, with any luck, intercept the encryption process before it has gotten too late but the likelihood of this happening is relatively low.
If you are struggling with .Promos and if your file have gotten locked by it we advise you to go to our removal guide and follow its steps to remove the infection after which you can use the suggested data recovery methods to restore some of your files. Sadly, there’s no guarantee that your data would be made accessible again even if you do everything as described. However, the same applies to the ransom-payment option. Unless you have run out of alternatives and you really need those files back, we advise you to abstain from taking the ransom-payment course of action as you can never be sure whether you’d actually receive the key for your locked-up data.
Another very important thing to remember is to ensure that your PC stays safe from now on – do not take any chances and keep away from web addresses with suspicious contents and do not interact with anything that might represent a potential software hazard. Also, make a backup of any important or valuable data which you might fear losing. Save the important files on a separate device and no virus should be able to reach them as long as you take care of the backup in a proper way without exposing it to potential risk.

Remove .Promos Ransomware Virus
Note: Before you go any further, we advise you to bookmark this page or have it open on a separate device such as your smartphone or another PC. Some of the steps might require you to exit your browser on this PC.
2: Task Manager
Press Ctrl + Shift + Esc to enter the Task Manager. Go to the Tab labeled Processes (Details for Win 8/10). Carefully look through the list of processes that are currently active on you PC.
If any of them seems shady, consumes too much RAM/CPU or has some strange description or no description at all, right-click on it, select Open File Location and delete everything there.
Also, even if you do not delete the files, be sure to stop the process by right-clicking on it and selecting End Process.
3: The Hosts file
Go to c:\windows\system32\drivers\etc\hosts. Open the hosts file with notepad.
Find where it says Localhost and take a look below that.
If you see any IP addresses there (below Localhost) send them to us here, in the comments since they might be coming from the virus.
To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.
If you want to avoid the risk, we recommend downloading SpyHunter - a professional malware removal tool - to see whether it will find malicious programs on your PC.
4: Disable Startup programs
Re-open the Start Menu and type msconfig.
Click on the first search result. In the next window, go to the Startup tab. If you are on Win 10, it will send you to the Startup part of the task manager instead, as in the picture:
If you see any sketchy/shady looking entries in the list with an unknown manufacturer or a manufacturer name that looks suspicious , disable those programs and select OK.
5: Registry Editor
Press Windows key + R and in the resulting window type regedit.
Now, press Ctrl + F and type the name of the virus.
Delete everything that gets found. If you are not sure about whether to delete something, do not hesitate to ask us in the comments. Keep in mind that if you delete the wrong thing, you might cause all sorts of issues to your PC.
6: Deleting potentially malicious data
Type each of the following locations in the Windows search box and hit enter to open the locations:
Delete everything you see in Temp linked to .Promos Ransomware. About the other folders, sort their contents by date and delete only the most recent entries. As always, if you are not sure about something, write to us in the comment section.
The previous steps were all aimed at removing the .Promos Ransomware from your PC. However, in order to regain access to your files, you will also need to decrypt them or restore them. For that, we have a separate article with detailed instructions on what you have to do in order to unlock your data. Here is a link to that guide.
