DONEX Virus 🔐 (.F58A66B51 Files) — How to Remove?

The Donex virus belongs under the ransomware type of infection. Harmful software of this type encrypts all user’s data on the computer (photos, documents, excel tables, music, videos, etc) and adds its specific extension to every file, leaving the Readme.[victim\’s_ID].txt text files in each directory with the encrypted files.

Donex virus: what is known so far?

The renaming will be executed by the following scheme: %filename%.victim_ID. In the course of encryption, a file named, for example, “report.docx” will be renamed to “report.docx.f58A66B51”.

In every directory that contains the encrypted files, a Readme.[victim\’s_ID].txt text file will appear. In our case, it was named Readme.f58A66B51.txt. It is a ransom money note. Therein you can find information about the ways of contacting the racketeers and some other remarks. The ransom note usually contains a description of how to buy the decryption tool from the tamperers. You can obtain this decryptor after contacting [email protected] by email. That is pretty much the scheme of the felony.

How did Donex ransomware end up on my PC?

There are many possible ways of ransomware infiltration.

Nowadays, there are three most popular methods for tamperers to have the Donex virus settled in your system. These are email spam, Trojan injection and peer-to-peer networks.

• If you access your inbox and see emails that look just like notifications from utility services providers, postal agencies like FedEx, Internet providers, and whatnot, but whose mailer is strange to you, be wary of opening those emails. They are very likely to have a harmful file enclosed in them. So it is even riskier to download any attachments that come with letters like these.
• Another option for ransom hunters is a Trojan file model. A Trojan is a program that infiltrates into your computer disguised as something legal. For instance, you download an installer for some program you need or an update for some software. However, what is unpacked turns out to be a harmful agent that compromises your data. As the installation wizard can have any name and any icon, you’d better be sure that you can trust the source of the things you’re downloading. The optimal thing is to use the software developers’ official websites.
• As for the peer-to-peer file transfer protocols like torrents or eMule, the threat is that they are even more trust-based than the rest of the Internet. You can never know what you download until you get it. Our suggestion is that you use trustworthy websites. Also, it is a good idea to scan the directory containing the downloaded objects with the anti-malware utility as soon as the downloading is complete.

How do I get rid of ransomware?

It is crucial to inform you that besides encrypting your files, the Donex virus will most likely install Vidar Stealer on your PC to seize your credentials to various accounts (including cryptocurrency wallets). The mentioned spyware can extract your credentials from your browser’s auto-filling cardfile.

How сan I avoid ransomware infection?

Donex ransomware doesn’t have a endless power, so as any similar malware.

You can armour yourself from ransomware injection in several easy steps:

• Never open any letters from unknown senders with strange addresses, or with content that has likely no connection to something you are waiting for (how can you win in a money prize draw without even taking part in it?). In case the email subject is likely something you are waiting for, check all elements of the dubious email carefully. A fake email will surely have a mistake.
• Avoid using cracked or unknown programs. Trojans are often spreaded as an element of cracked products, possibly as a “patch” preventing the license check. Understandably, dubious programs are difficult to tell from trustworthy ones, because trojans may also have the functionality you seek. You can try searching for information on this program on the anti-malware message boards, but the optimal way is not to use such programs at all.
