How to remove Donut virus and restore encrypted files

Our item will help our readers to remove Donut encrypting malware. On this page, we'll present you the very effective tips on Donut removal, coupled with wittings about the decryption of wasted files. Here we have the common hints on encrypting viruses that will assist you to evade infection in future.

Donut ransomware virus

Ransomware is the worst trouble which belongs to the list of the hairiest threats on the Internet. It is a pure pillage, only without alive plunderers involved: web-criminals penetrate the PC and take everything they wish, casting a victim aside with a crippled hard drive that contains only corrupted data. Donut virus is the brightest instance of encrypting programs: it’s not difficult to find and just impossible to beat, but there are some measures you should take. On this page, we want to explain to you the significant rules of Donut's work and how it infected the system. We will make it clear to you in which methods you can evade encrypting virus' penetration, and how you can get your information back. Don't forget that many the suchlike viruses won't ever get defeated, and if you've got one – the information may be already gone completely. In some cases swindlers make a mistake to create the way to neutralize ransomware or to reverse the caused harm. The user may be guarded by some settings of his PC, and we'll teach you how you can use it.

What is Donut ransomware and how it works

The code of an encrypting virus isn't really complex, but even the most carelessly designed virus is very perilous, and we will tell you why. They all use the very strong methods of encryption. Malicious programs' task is not to take the information. It only has to infect the machine, encode the data and remove the originals, placing the encrypted copies instead of them. You can't use those data if they are encoded. You can’t use them and can’t bring them to their previous state. There are several techniques to reconstruct the files, and they all are explained in our piece.

The point is that the common encrypting programs take advantage of the well-known ciphers, such as the RSA and the AES. These two are very complex and cannot be decrypted. Actually, you might decrypt them if you have fifty years of the home PC’s working time or a couple of years of operation on the most productive computer of the world. We're sure that neither of the given options is suitable you. The perfect method to defeat an encrypting program is to not let it get onto the PC, and we will tell you how it could be done.

The encrypting malware, AKA ransomware, are the programs that get into customers' PC's and encode their files to ask money from them. More often than not, fraudsters get on user's device via malspam campaigns or zero-day Trojans. Dangerous mail isn't hard to identify – it will be a message suddenly, and it will have some files attached to it. In case of 0-day vulnerabilities, it’s a bit harder – you'll never feel it coming until you get infected which means that the most efficient way is to automatically download the latest updates for the OS and other programs that you use.

If the ciphering is finished, ransomware shows you a ransom message, and when you see it – it's too late. There's only one thing you can do now - to erase Donut from the hard drive and attempt to reconstruct the files. We've said “attempt” since the odds to handle it not having a decryptor are faint.

Donut removal guide

You need to eliminate a virus before you go on as if it sticks in the system – it will go on encrypting each file which comes into the system. Even more - every flash drive you are sticking into the infested device will get encrypted also. To evade this – delete Donut through sticking to this useful advice. Remember that the uninstallation won’t restore the files, and if you do this, you won’t be able to pay money to scammers. We offer doing that as every dollar earned makes fraudsters more to feel their feet in their "business" and increases their money to develop intricate encrypting programs. It's worth mentioning that when you’re forced to deal with web-criminals, there’s no proof that the information will be decrypted when they have the money. They’ve already wasted your information, and you, supposedly, don't lean to send them some funds on top of that.

Donut decryption instruction

After Donut is removed from the computer, and you're certain about it, you need to think about the restoration ways. Primarily, we want to say that the very proven way is to use a backup. In case you have the copies of the data and Donut is totally removed – simply erase the spoiled files and upload the copies. In case you have no backups – the chances to get your files are much lower. Shadow Volume Copies service is a thing that helps you to do it. It’s the basic tool of the Windows OS, and it copies all the modified or removed data. They can be reached with the help of custom restoration programs.

Unfortunately, all modern viruses can delete these copies, but if you're accessing the system from an account that has no master rights, Donut simply had no way perform that not having your order. You might remember that a few minutes prior to the showing of a hacker's letter there was a different dialogue window, asking to apply alterations to the system. If you've cancelled these changes – the copies weren't removed, and you may use them and repair your files with the help of such utilities as Recuva or ShadowExplorer. You can easily find them both on the Internet. Each of them has its official pages, so you have to download them there, with tested guides. If you require more explanations on this topic – just read this entry about data recovery: article about files decryption.
