Decme virus Removal Guide

What is Decme ransomware?

Decme ransomware – a cryptovirus that encrypts all files and appends a three-part extension to them

Decme ransomwareDecme ransomware is the cryptovirus that asks for money by claiming to have a decryption tool.

Decme ransomware is a file-locking parasite that, after it gains access to a computer it encrypts all files and demands a ransom for a promised decryption tool. This cryptovirus belongs to a small Voidcrypt ransomware family, with members like Shiton, Lalaland, Konx, and others.

During the encryption[1] process, the Decme ransomware virus appends all non-system files, like documents, archives, pics, etc., with a triple extension: email address of the criminals in brackets, appointed victim ID also in brackets, and .decme extension. When the encryption is done, files are rendered inaccessible.

When encoding of all personal user data is completed, the Decme file virus creates ransom notes, titled !INFO.HTA, in all folders with encrypted files so that the victims of the cyber attack would find them effortlessly, wherever they look.

System health Malware typically corrupts system files, so after Decme ransomware removal, we recommend using the ReimageIntego tool to undo all changes and harm done to the device's core files and settings

The ransom note (posted below this article) of Decme ransomware isn't very informative, unlike other cryptoviruses, e.g., Lisp. In the beginning, the virus developers explain that all files were encrypted with a strong cryptography algorithm and that the only way to regain access to them is by paying the hackers.

The ransom amount isn't specified, although the cybercriminals urge to contact and pay the ransom within 48 hours of the infection or the demanded ransom will be doubled. The creators of Decme ransomware, like most of the hackers, would like to be paid in cryptocurrency Bitcoins.

To prove that they really possess the required tools for .decme file decryption, the cybercriminals are offering the victim to send them some small files (not containing any valuable data) for free test decryption. They also provide two emails to establish contact – Files2021@tutanota.com and Files2020@mailfence.com, and an appointed unique user ID.

We always advise against contacting the cybercriminals and agreeing to meet their demands. Victims should remove Decme ransomware from their infected devices and look for other means of data recovery. The longer any malware stays in a computer, the more damage it could do.

The most typical methods of the cybercriminals used to infect computers

Different types of malware[3] are spread in different ways. for example, adware is spread mostly with freeware installation bundles, while ransomware is distributed mainly by spam emails and through file-sharing platforms. Cybercriminals are creating more viruses each day, so read our articles, and you might evade it.

Decme file virusDecme ransomware is a virus that makes data useless after encryption.

Spam emails containing either mischievous hyperlinks or infected attachments are sent out each day in tens of thousands. If any of these villainous options are clicked or downloaded, the infection and encryption start almost instantly. Be aware of these emails, and please never open any shady-looking emails or their components.

Torrent websites, like BitTorrent, The Pirate Bay, and others, are full of different malware. It's an ideal environment to spread cryptoviruses because no one is scanning the files and assuring end-users security. Please refrain from using any torrent sites.

How to prevent from getting ransomware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.

 

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
