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

The purpose of a Ransomware cryptovirus is not to corrupt some crucial system files in your computer or to spy on your activities without you knowing it. A Ransomware will not delete personal data from your computer or give remote control over the infected machine to the hackers who are responsible for the malware attack. However, despite all this, the Ransomware viruses and their cryptovirus subcategory in particular are among the worst forms of malware that could potentially find their way to your computer and files. Unlike Trojans, Spyware, Rootkits and other categories of malware that may corrupt data, spy on you or block your antivirus, a typical cryptovirus would use a rather harmless computer process called file encryption to fulfil its quite nefarious purpose. The goal of the Ransomware cryptovirus is to make it impossible for you to open, use, edit or modify all potentially important personal data stored on your computer. Naturally, if you find out that all important files in your system won’t open no matter what you do, you’d be eager to find a way to get them to be accessible again. This is normally the point where the hackers tell you about their “offer”, namely the option to pay them a certain amount of money (usually in the form of some cryptocurrency like BitCoin) and, by doing so, be sent a restoration key for your files that can allow your computer to read through the encryption placed on the data. Of course, trusting such promises made by hackers who are blackmailing you isn’t exactly a very good option. After all, you may simply end up wasting a significant amount of money and still remain without the means to open any of your data.

.Stun Ransomware File

.Stun Ransomware is a nasty cryptovirus that works in this way and if you have come here because of this exact infection, you might want to read and apply the next removal steps that should help you eliminate the Ransomware.

Concerning the future of your files

It must be noted that getting your files encrypted by Ransomware makes the future of the locked data uncertain. You can try paying the ransom and you may or may not get the data decrypted by doing so and there is no way of knowing what will happen. Sadly, however, even if you use the guide from this page and manage to remove .Stun from your computer, you may still fail to recover the inaccessible data. The removal of the virus itself is typically not enough to bring down the decryption and though we have also offered our readers some potential restoration solutions for the locked-up files, we cannot promise that any of them will work for each user. Trying the guide out, however, will at least help you clean your PC which is an important step towards handling the situation as that would, at the very least, make your system safe and prevent .Stun from locking-up any new files that get created or downloaded onto your machine.
