If we would have to point out a single most devastating malware type, it would hands down be ransomware. This malicious piece of software been enjoying a growth spurt over the past years like no other; and not only in numbers, but also in development and sophistication. Unfortunately, ransomware viruses are a step ahead of the cyber security community, which makes them incredibly difficult to deal with.
There’s also much money from this type of malware, which is also why it’s been experiencing such unheard of success. Today we would like to focus on a particular representative of this cryptovirus category called Wanna Decryptor Virus and the reason why it’s called that, is because it encrypts certain files on the victim’s computer. And if you’ve already come face to face with this horrible threat, then you also know that afterwards it tends to try and blackmail the victim user for money in exchange for granting them back their access to the affected files. The purpose of the following article is to clarify the way ransomware operates, so that you may have a better chance of protecting yourself from it in the future. But we also want to try and help you remove Wanna Decryptor Virus from your system and try and restore some of your files. You will find instructions on how to do that in the removal guide that follows.
What makes ransomware such a successful threat?
Ransomware viruses typically act with great stealth and are practically impossible to notice, up until they decide to reveal themselves with the ransom note on the victim’s screen. At that point it’s already too late to prevent anything from happening and the hackers are eager to state their demands, so as to receive their ransom payment. This is largely true because of the principles that ransomware and other viruses like Wanna Decryptor Virus operate on. You see, once inside the system, they begin to create encrypted copies of the specific file types they’re after, such as video and audio files, word files, images, etc. After this, they delete the originals, leaving the victims with the encrypted copies, which cannot be accessed without a decryption key. Now, the process of encryption is not in itself a malicious one, which is why most security software will fail to detect it as a threat.
Thanks to this crucial aspect the ransomware is able to carry out its evil plan, undisturbed by anyone. Another vital component of its success are its distribution techniques, which are just as stealthy and will also do little to reveal that you’ve actually been infected by a potentially devastating crypto-virus. The most common ways of getting infected include malvertisements (or fake, corrupted online ads) and spam emails. They may sometimes contain a Trojan horse, which is notorious for its stealth, so you may have ended up downloading the Trojan first, which in turn then proceeded to automatically download Wanna Decryptor Virus onto your PC. Since this is frequently the case, we would recommend that you also scan your computer for a Trojan horse virus, as removing Wanna Decryptor Virus will not remove the other malware.
Downloadable content from various shady and possibly illegal websites could potentially also be infected with ransomware or other malware. It’s highly important that you mind your download sources and be very careful with the ones you choose to get your software or other content from. We would recommend only relying on trustworthy and reputable platforms and steering clear from anything less than that. The same goes for the malvertisements that we mentioned earlier. Though you may come across a malicious ad like a banner or popup literally anywhere on the web, this is more likely to be the case on an illegal or obscure website.
As far as other means of preventing future ransomware infections go, we would also suggest exercising caution when it comes to incoming email or other correspondence. Hackers may often try to disguise their malicious messages as something legit and will try to trick you into loading an attached file or following a link. Take extra precautions to ensure that you can trust the sender and the message itself before opening it or anything in it. Last but not least, the best way to disarm any ransomware, even one that’s already gotten inside your system, is to have backed up your most important data beforehand and stored it on a separate drive.
Wanna Decryptor 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.
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.
