.VIRUS ransomware removal instructions

What is .VIRUS?

Credit for discovering .VIRUS belongs to Jakub Kroustek. It is a piece of malicious software, categorized as ransomware. This program operates by encrypting data and demanding a ransom (i.e. payment for decryption software/tools). As .VIRUS encrypts, it renames all files with victim's unique ID number, its developers email address and ".VIRUS" extension. Therefore, a file like "1.jpg" would appear as something similar to "[].VIRUS", and so forth. After this process is complete, a text file ("FILES ENCRYPTED.txt") is created on the desktop and a pop-up widow is displayed. This infection belongs to Dharma ransomware family.

The text file informs victims that their data has been locked, to retrieve it they must write to the email addresses provided. The message in the pop-up window is a more detailed ransom note. It repeats that all of the users' files have been encrypted and to recover them, they must contact the developers of .VIRUS. The email has to have the unique ID number in the title/subject. If no answer comes in 24 hours, victims are to use the other email address. The size of the ransom is not stated, it will depend on how quickly the cyber criminals are contacted. The payment will have to be made in Bitcoin cryptocurrency and there is information listed on how to procure said currency. As proof of their ability to restore the data, the criminals offer to decrypt one file free of charge. Provided, if the file is no larger than 1Mb (non-archived) and contains no valuable information, such as database, backup, large excel sheet, etc. Users are warned not to rename the files and not to attempt manual decryption with third party software - as that will result in permanent data loss. Unfortunately, usually only the ransomware program used to encrypt the data - is capable of decrypting it. Despite this, it is expressly advised against meeting the ransom demands and/or communicating with cyber criminals. Often, even though the victims pay - they do not receive the promised tools. Therefore, their data remains encrypted and beyond repair. Removal of this malicious software will not restore the affected files, but it will prevent .VIRUS from further encryptions. The only viable solution is recovering the encrypted data from a backup, if one was made before the infection and stored separately.

.VIRUS decrypt instructions

Most ransomware is similar, for example Meka2HamlampampomAsus are akin to .VIRUS. All malware of this type encrypts data and demands a ransom to be paid. However, they differ by the cryptographic algorithm they use (symmetric or asymmetric) and by the size of the demanded payment. Ransom sizes typically range between three-digit and four-digit sums. Cyber criminals tend to prefer digital currencies (e.g. cryptocurrencies, pre-paid vouchers, etc.), as transactions of such are difficult/impossible to trace. Unless a certain ransomware is still in development and/or has flaws/bugs, manual decryption (without its developers interference) - is impossible. To ensure data safety, it is recommended to keep backup copies in unplugged storage devices and/or remote servers. Since both are liable to damage, it is best to store several backups in different locations.

How did ransomware infect my computer?

Ransomware and other malware is commonly spread via trojans, spam campaigns, untrustworthy download channels, fake software updaters and "cracking" (activation) tools. Trojans are a type of malware, which operate by downloading/installing additional malicious programs. Spam campaigns are used to send out large number of deceptive/scam emails, containing virulent attachments (or web-links leading to them). This mail is often highlighted as "official", "important", "urgent" or with other priority labels. The attachments can come in variety of formats, such as archive and executable files, Microsoft Office and PDF documents, JavaScript, etc. Once these files are run, executed or otherwise opened - they cause the infection. Peer-to-Peer sharing networks (BitTorrent, eMule, Gnutella, etc.), unofficial and free file-hosting websites, third party downloaders and similar sources are deemed to be untrustworthy. Unreliable download sources can offer deceptive and/or bundled content. By exploiting the weaknesses of outdated software, fake updaters infect systems. However, they can simply install malware, instead of the promised updates. "Cracking" tools can download/install malicious programs rather than activate licensed product.

How to protect yourself from ransomware infections?

It is recommended not to open irrelevant emails, especially mail received form unknown senders (addresses). Any attachments (or links) in them - must never be opened, as that can trigger them to download/install malware. Software should be downloaded only from official and verified channels. Program activation and updating should also be done only through legitimate functions/tools; illegal activation ("cracking") tools and third party updaters are considered to be high-risk and are discouraged from use. It is strongly advised to have a dependable anti-virus/anti-spyware software installed and kept up-to-date. It is to be used for regular system scans and removal of potential threats. If your computer is already infected with .VIRUS, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
