How to remove Copa virus and restore encrypted files

This item was created to assist users to delete Copa ransomware. On this page, we'll show you all you need to learn about Copa elimination, alongside with information on data recovery. We also provide the overall hints about ransomware that will help you to evade penetration in future.

Copa ransomware virus

Copa is the worst disaster that is on the list of the hairiest viruses of the Web. It is a pure plunder, only without living pillagers involved: web-criminals get into the device and loot all they need, leaving a user with a crippled system, filled with corrupted data. Copa virus is the clearest illustration of this type of malware: it’s easy to find and too difficult to uninstall, but there are some measures you can take. In this guide, we want to tell you the basic principles of Copa's work and the ways of its penetration into your system. We'll explain to you how you can avoid encrypting virus' infestation, and how you can decrypt your files. Remember that most of these viruses won't ever get beaten, and if you have one – your files may be already gone for good. Rarely even swindlers make an error to develop the way to remove ransomware or to reverse the caused harm. The customer can be protected by some controls of his PC, and we will teach you how to use it.

What is Copa ransomware

 

Regular ransomware programs are not overly complicated in their structure, but even the clumsiest virus is highly dangerous, and we can explain to you why. The catch is about the encoding algorithms. Malicious programs' goal is not to take your information. Everything it wants to do is to infest the system, encode your information and erase the real data, placing the encrypted copies instead of them. The files are unusuable if they are encoded. You can’t read the files and can’t bring them to norm. We know several techniques to restore the files, and we've defined them all in this article.

The encrypting programs, also known as ransomware, are the viruses that infect customers' systems and encrypt their files to ask money from them. Most times, fraudsters get on user's computer via malspam campaigns or 0-day Trojans. E-mail spam isn't hard to recognize – it will be sent from an unknown address, with a file in it. In case of zero-day Trojans, it’s a bit harder – you won’t know what it is until the machine gets penetrated so that the most efficient way is to regularly download the newest updates for the OS and other programs which you have in it.

The thing is that modern encrypting programs utilize the famous encoding systems, known as the RSA and the AES. These two are literally the very complex in the world, and an ordinary user can't decrypt them. Of course, you may decipher them, having fifty years of your home PC’s working time or a couple of years of operation on the very efficient machine of the world. We don't think that any of these options is suitable a victim. The perfect method to defeat an encrypting virus is to decline its installation, and we will explain to you how to do that.

If the ciphering is performed, fraudsters show you a letter with demands, and when it popped up – it's too late. The smartest thing you can do now - to eliminate Copa from your device and try to reconstruct the files. We've said “attempt” as the probability to succeed not having a decryptor are faint.

How to remove Copa

It’s crucial to remove a virus until you go on as if it remains on your computer – it will begin encrypting any file which comes into the computer. You have to understand that any device you're connecting to the infected device will become corrupted also. We're sure that you don't want it, so just uninstall Copa by adhering our useful advice. Don't forget that this won’t decrypt the files, and after doing it, you will not be able to pay money to scammers. It will be wise that because each ransom received makes hackers more positive in fraud schemes and gives them more budget to develop complex viruses. Significant point is that if you are dealing with fraudsters, you have no guarantee that the information will be decrypted after you pay the money. They have already decrypted your information, and we don't think that you want to give them the ransom on top of that.

How to decrypt Copa files

After Copa is uninstalled from your computer, and you're sure about it, it’s time to think about the decryption methods. Firstly, we should notice that the sole 100% proven technique is to use the previously saved copies. In case you had the backups of the data and the ransomware is totally eliminated – don't worry. Erase the encrypted files and load the copies. If you have no backups – the probability of recovering your data are significantly lower. Shadow Volume Copies tool is what helps you to do it. We're saying about the inbuilt tool of Windows, and it copies each bit of information that was modified. You can access them via specific recovery programs.

No doubt, the modern viruses can eliminate these files, but if you're working from an entry without administrator rights, the virus simply couldn’t do that without the order. You may recollect that several minutes prior to the showing of a ransom note you've seen another menu, suggesting to make changes to your system. If you have declined those alterations – your SVC weren't erased, and they might be found and used with the help of the programs as Recuva or ShadowExplorer. You may simply find them both in the Net. Both of them have their main pages, so you should download them from there, with detailed guides.
