Coverton virus Removal Guide

What is Coverton virus?

How dangerous is the Coverton virus?

Everyone has some precious files on their computers that they value, but Coverton virus is a malicious program which can put the safety of your files at stake. This virus is categorized as a ransomware-type program which hijacks the user’s computers and locks the containing data. For the encryption of the files, it uses a very complex AES-256 encryption algorithm, which cannot be decrypted without a specific decryption key. Even though it’s a relatively recent malicious creation, Coverton works identically to such famous ransomware like Locky, CryptoWall or CryptoLocker. They all demand ransom for the decryption of the files and in this way make illegal profit. If you suddenly notice that you cannot access your files anymore, and they all feature an unusual .coverton extension instead of the regular ones, this means you have been a victim of the Coverton virus. If such unfortunate situation occurs, you must immediately eliminate the virus from your computer. For this, you will need some acknowledged antivirus tools. We recommend FortectIntego since this program not only removes the viruses which may be already residing on your PC but, most importantly, prevents them from infiltrating the system in the first place. Therefore, if you obtain antivirus while you are not still infected, you may not even have to deal with the Coverton removal.

However, if the virus has already hijacked your computer, there are several things you need to know about how it works. Usually, it enters the computer through infected email attachments, and once it is activated, it installs its infectious executive files in different directories on your computer. For this reason, it is almost impossible to suspect your computer has been infiltrated. Of course, you may notice some slight changes like slowing down of your system and other minor system errors. Otherwise, there are no other indicators which might reveal that your computer is being attacked. Once the virus installs its components on the computer, it starts scanning the system for files. Different photo, video, files, documents and similar data are the primary targets of Coverton encryption. After the files are encrypted, a text or HTML files, labeled as “!!!-WARNING-!!!.txt” or “!!!-WARNING-!!!.html” are then created on every folder containing the encrypted files. These files contain information about the current state of the computer and provide instructions on how to retrieve the locked files. The victim is offered to pay a considerable amount of money to gain access to a personalized Coverton decryption key, which is kept by the cyber criminals on a remote server and cannot be obtained in any way other than paying the ransom. However, it is highly not recommended to try buying out your files. You have to remember, that you are dealing with cyber criminals, whose main goal is to generate revenue, and giving your files back is the least of their concern. Therefore, since there is no known way of retrieving the data, and paying up is not a safe option either, the best decision is to remove Coverton from your computer completely, and prevent further damage to the system.

How can this virus hijack my computer and is there a way to prevent it?

It is not difficult for malicious programs like these to enter your computer. As mentioned before, the threat is only a few clicks away, if you are not safe about browsing the web. As it spreads through emails, it is important that you are careful about opening newly received correspondence, and especially, downloading files potentially attached to it. Always make sure that source of the email is reliable and stay aways from the “Spam” section. Usually, reputable email providers recognize the potentially infectious emails and automatically place them in the “Spam” category. You can also prevent this virus from entering your computer by equipping your device with a trustworthy antivirus suite, which should detect the threat and inform you about it at once. However, if you feel very protective of your files, the only way to truly ensure their safety is by creating backups and keeping them in some external hard drive, USB drive, CDs or DVDs.

There are two main aspects you should know if you want to remove Coverton from your computer. Despite it is a very dangerous program, there are still ways to get rid of it.

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
