If you have some valuable files, which you store solely on your computer, being infected with Ransomware like Aes-ni Ransomware can be a real nightmare. This threat is able to encrypt all of your files, render them inaccessible and ask you to pay ransom to access them again. Releasing them from the encryption can be a very tricky and challenging task, which may not always end with success. However, you should not give up unless you’ve tried everything possible, right? For that, you should be well-informed about the specifics and the typical tricks that Ransomware uses in order to extort money from its victims, as well as the possible methods to remove such infections and eventually minimize some of their harmful consequences. In the next lines, we are going to cover exactly that, so stay with us if you really are looking for an alternative solution.

How can one catch a threat like Aes-ni Ransomware?

There are several ways to catch a Ransomware infection like Aes-ni Ransomware and some of the most common include clicking on spam messages, emails with malicious attachments, shady websites, sketchy links, ads and infected installers as well as well-camouflaged Trojan horse transmitters. To keep your computer protected, it is very important to stay away from such shady pieces of content and not to click on different random messages, ads, and links that appear on your screen. A potential Ransomware attack may be prevented also if you keep your system safe and regularly updated. If there are vulnerabilities such as outdated software, expired virus definitions of your current antivirus program, and some shady or potentially unwanted programs, they can easily be exploited by malware like Aes-ni Ransomware. So, make sure you keep your PC safe by using good and updated security tools and applying some common safety measures. Also, to prevent potential data loss, always backup your most important files and keep their copies in some other location such as an external drive or a cloud. This is a smart move, which can really save you from the nightmare of having your files encrypted and not having access to them.

The general purpose of Aes-ni Ransomware is to blackmail you!

Ransomware is a very problematic type of malware. It is basically used to block the access to either your entire machine by locking your screen (Screen-locking Ransomware) or to all the data found on it, by encrypting each and every file on your hard drive (File-encrypting Ransomware). The idea behind preventing your access is to blackmail you to pay a ransom. The current threat that we are discussing here is a representative of the File-encrypting Ransomware category, and as such, it has no intention to spare you or any of your files! Its general purpose is to get inside your PC, apply a very complex encryption algorithm to all the data found on your hard drives, and then place a ransom note on your screen, with which it will ruthlessly blackmail you for the access to your own data! Unfortunately, unlike the Screen-locking Ransomware type, which doesn’t cause any actual harm to your PC apart from blocking your access to it, the File-encrypting Ransomware is harder to handle, because even removing the infection may not reverse its harmful consequences on your data and restore it back to normal. This is one of the main reasons why threats like Aes-ni Ransomware are seen as a serious danger, which poses a real challenge even to experienced security experts.

Regaining access to the encrypted files – is it possible?

Regaining access to the encrypted files usually requires a special decryption key, which is held by the criminals. The victims are promised to receive this key only if they pay the ransom according to the instructions and deadlines, shown in the ransom note. This promise, however, is usually just a simple trick and does not guarantee you anything. Even if you strictly fulfill all of their instructions and ransom demands, you may still not be able to save your data. The likelihood of you receiving a decryption key once you have paid is very minimal because the criminals usually disappear with the money and nobody hears from them again. Having this in mind, it is best if you don’t rush with any payment and seek for some other alternatives to deal with Aes-ni Ransomware instead. What we can suggest you is to remove the Ransomware infection and try to restore some of your encrypted files by using the instructions in the removal guide below. We can’t tell you exactly how effective they will work in your specific case, and how much of your files you will be able to save, but you will lose nothing if you try the steps shown below to combat Aes-ni Ransomware and its nasty encryption to some extent.

Aes-ni Ransomware 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.
