This page aims to help you remove MongoLock Ransomware for free. Our instructions also cover how any MongoLock file can be recovered.

If you have never encountered a Ransomware PC virus, you can consider yourself lucky in that regard. This category if dangerous and harmful software programs are currently a cyber-threat nightmare due to two main reasons – they are extremely difficult to detect and just as tricky (if not more) to deal with after they have infected a computer system. One peculiar thing about this particular form of malware is that it doesn’t really harm anything on the PC (at least initially). Most Ransomware viruses take a different approach in comparison to most other illegal and harmful programs. Instead of causing system, data or software corruption and instead of seeking to mess with the user’s virtual identity, Ransomware infections simply lock the user’s personal files with a complex encryption or they block the actual screen of the infected machine. MongoLock Virus, a recently released cryptovirus type of Ransomware belongs to the former subcategory of these viruses – the one that encrypts the personal user files rendering them inaccessible. Since it is a relatively new infection, the number of victims that have been affected by it is currently steadily going up which is one of the main reasons we are writing this.

Our suggestion

Helping unfortunate users who have landed viruses such as this one is what we do and if you are currently looking for assistance with the removal of the malware threat that MongoLock is, you have come to the right place. In the next lines, we will provide you with some important details related to Ransomware viruses the likes of MongoLock and we will also give you some ideas on how to fight this particular kind of malware as well as how to keep it away from your PC in future. A detailed removal guide that has been added down below will show you the different methods that you can try to get rid of the malicious piece of software.

Note, however, that removing the virus and getting your files recovered are two different things. While the chances of you managing to get rid of the infection are rather high, restoring the access to your files is a whole different story. Although our guide also includes suggestions regarding how you might be able to release your data, we cannot promise anything. This is actually what the hackers behind MongoLock are counting on. Once your data gets locked, they offer to send you a decryption key if you agree to send them a certain amount of money. This is basically the whole purpose of this virus – to facilitate the cyber-criminals’ blackmailing scheme. Now, you can choose to ignore our suggestions and instead of trying our guide and the data recovery methods that we have added to it and directly make the payment. However, we ought to tell you that paying the money also doesn’t guarantee successful data recovery – nothing can make the hackers send you the key to your sealed files regardless of whether you carry out the transaction or not. Sometimes, some users get lucky after paying and are indeed given the means to regain access to the files but this is not always the case. In the end, it is up to each individual to decide for themselves yet our advice for all potential victims of MongoLock is to first try out our free Removal guide and its data recovery instructions (that might or might not work) and only then, if you still believe that it’s worth it, consider risking your money by sending them to criminals that you certainly cannot trust.

Why you must stay protected at all costs

Ransomware, as we said above, is both really difficult to detect and very tricky to deal with after an infection has already occurred. This is especially true when talking about cryptoviruses like MongoLock. Because of their use of encryption – a process that normally isn’t regarded as harmful, spotting such a malware is made highly unlikely even if there’s a reliable antivirus program installed on the targeted computer. Needless to say, there are also pretty much no symptoms other than occasional decrease in the productivity capabilities of the computer (in other words, a slowdown) due to higher use of RAM and CPU which is oftentimes difficult to notice.

Due to all of this, your best bet for potential future encounters with Ransomware is to simple make sure that the virus never enters your system. To make sure your machine stays safe and secure, we highly recommend you never visit any unreliable or sketchy-looking web locations and that you never download software from sources that may not be trustworthy. Needless to say, you are not supposed to open shady e-mails that might be spam and interact with any links or file-attachments they might hold. The same applies to any other form and type of questionable online content – suspicious ads, misleading web offers, fishy-looking banners and pop-ups, you get the idea. A great tip when it comes to keeping your most important data secured is to have all of it backed up on a separate location – it could be a cloud or an external drive, just make sure that you always have backup co pies of any files that are valuable to you. Now, if MongoLock is currently on your machine and your data has already been sealed by it, you can take a look at our removal guide manual and see if it does the job for you.
