N2019cov ransomware removal instructions

What is N2019cov?

Discovered by MalwareHunterTeam, n2019cov is a ransomware-type malicious program. Systems infected with this malware have their data encrypted and receive ransom demands for the decryption tools/software. During the encryption process all affected files are appended with the ".P4WN3D" extension. Therefore, a file titled something like "1.jpg" would appear as "1.jpg.P4WN3D" - following encryption. Afterwards a ransom note - "1nF0rM@t1On.txt" is created.

The ransom-demanding message in "1nF0rM@t1On.txt" informs victims that their data has been encrypted. Though in the note, it is phrased as "Files Has Been Taken". To get the appropriate decryption tools/software, users are told that they must pay a ransom - whether to do so is their choice. The price of the decryption tools is stated to be 100 USD in Bitcoin cryptocurrency. If victims are unfamiliar with this currency, the message contains a link to a site, detailing how to do so. After the sum is transferred into the cyber criminals' cryptowallet, they are to send proof to the email address provided in the note. Following this, they are promised to receive all that they need for to recover their data. Unfortunately, in most cases of ransomware infections, without the interference of the criminals responsible - decryption is impossible. It may be, if the malicious software in question is still in development and/or has significant bugs (flaws). Regardless of the circumstances, it is strongly advised against paying cyber criminals. These individuals are not to be trusted and often, despite meeting their demands - victims do not receive the promised decryption tools/software. Hence, the data remains encrypted (essentially, worthless) and users experience financial losses. To prevent N2019cov ransomware from further encryptions, it must be removed from the operating system. However, removal will not restore already encrypted files. The sole viable solution is recovering them from a backup, if one was created prior to the infection and was stored in a separate location.

VhdUPPER and C-VIR are a few examples of other programs classified as ransomware. Malware of this type is designed to encrypt data and demand payment for the decryption. There are two main differences between these programs/infections: the cryptographic algorithm they use (symmetric and asymmetric) and the ransom size. The latter typically range from three to four digits (in USD). Cyber criminals tend to prefer digital currencies (primarily, cryptocurrencies), due to transactions of them being difficult/impossible to trace. To avoid permanent data loss, it is highly recommended to keep backups in remote servers and/or unplugged storage devices (ideally, in multiple different locations).

How did ransomware infect my computer?

Ransomware and other malware is commonly proliferated via spam campaigns, trojans, software "cracking" (activation) tools, illegitimate updaters and untrustworthy download channels. Spam campaigns are used to send deceptive/scam emails on a mass scale. These letter have infectious files attached to (or linked inside) them. Malicious files can be in various formats (e.g. archive and executable files, PDF and Microsoft Office documents, JavaScript, etc.); when these files are opened - it triggers the infection process (i.e. download/installation of malware). Trojans are malicious programs, capable of causing chain infections. Rather than activate licensed products, "cracks" can download/install malicious software. Fake updaters infect systems by abusing weaknesses of outdated products and/or by simply installing malware instead of the promised updates. Malicious content can be unintentionally downloaded from untrustworthy sources, e.g. unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders.

How to protect yourself from ransomware infections?

Dubious and/or irrelevant emails should not be opened, especially any attachments (or links) found in such - as that can result in a malware infection. It is recommended to only use official and verified download sources. Additionally, all products should be activated and updated with tools/functions provided by legitimate developers. It is ill-advised to use illegal activation ("cracking") tools and third party updaters, since they are commonly used to proliferate malicious programs. To protect device integrity and user safety, it is crucial to have a reputable anti-virus installed and kept up-to-date. Furthermore, it should be used to run regular system scans and to remove detected/potential threats. If your computer is already infected with N2019cov, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the N2019cov ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining N2019cov ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of N2019cov are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by N2019cov, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as N2019cov ransomware.

Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites, and Desktop folders.

Controll Folder Access

Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
