C0v Virus File (Dharma Ransomware)

C0v Virus File (Dharma Ransomware)

c0v-virus-fileA new iteration of the Dharma ransomware family has been detected in the wild. Appending the .c0v ([c0v1d19@job4u.com].c0v) file extension to encrypted file, the c0v cryptovirus will demand a ransom payment from you to allegedly restore your files. However, we advise you to be extra careful and not get in touch with cybercriminals. There is no guarantee that your files will be restored, and by paying the ransomware operators, you will only enable their future malicious campaigns.

Note that the c0v file virus is currently being distributed across the web, targeting vulnerable Windows systems and users with weak protection and bad online habits. Don’t open suspicious or unexpected emails that contain an urgent subject line and attached files, as these emails could have been coined by the Dharma operators to spread their file-encrypting payload. Continue reading to learn more about the ways of ransomware distribution, and how to remove the c0v ransomware.

Another example of a Dharma variant is the .TomLe virus file, released in February 2021.

C0v Virus File – How Did It Sneak Into My Computer?

The most widespread techniques of spreading ransomware such as C0v virus file are pirated software and malicious email attachments. We can describe two of the most popular infection cases for you:

    1. You may have downloaded a form of suspicious software from an untrustworthy torrent or freeware platform. Users like you are often led to believe that downloading apps from such places is safe. In truth, most torrent websites contain unverified downloads that directly put you at risk of Trojans and ransomware. If you have downloaded a trojanized application, it may have opened the door to more severe infections, such as the C0v cryptovirus. We highly advise you to keep great online and computer hygiene. You should always keep an eye on pending software and operating system patches. This way, you will update them as soon as a critical or important patch arrives.
    2. You may have opened a malicious email attachment sent to you by a seemingly trustworthy sender, such as a company, or a company representative. Keep in mind that malspam operators use misleading tricks to make you open their emails. The attached file may look like a regular document, but in truth, it contains malicious code that could compromise your system severely. We advise you to disable macros in Microsoft Office applications. You can go to Microsoft’s support page on macros for more details. Note that if you are an enterprise user, the system administrator is in charge of the macro default settings.
    3. Long story short, opening an unexpected email attachment hides many risks and shouldn’t be done without additional verification. If you can’t define whether the attached archive is malicious or not, you can always refer to us for help!

Should You Pay the Demanded Ransom?

We believe that contacting cybercriminals is not a good idea. There is no guarantee you will get your files back, if you follow their requests and demands. Instead, we advise you to remove the virus from your system to prevent it from spreading further, and wait for an official decryption tool. In the meantime, you can try to restore your files via using an alternative method. More about this is available in the instructions below.

Remove C0V Virus File ([c0v1d19@job4u.com].c0v)

You can remove the cryptovirus by following the removal instructions below. We created these steps to navigate you through the removal process.

NOTE! If the manual removal steps don’t work for some reason, we would advise you to do what most cybersecurity experts would do – run a scan with an advanced anti-malware tool on your PC. Such a program aims to automatically detect and delete all malicious files and objects and protect your machine against future infections.

In terms of encryption of files locked by this Dharma variant, you can refer to the “Try to restore” step. Please note that the alternative solutions we have given may not recover all affected files, but you may be able to restore some of your data partially.
