How to remove Puma virus and restore encrypted files

This entry will help users to uninstall Puma ransomware. Here, we’ve assembled all you need to learn about Puma elimination, together with wittings on data restoration. We also provide the general tips about encrypting viruses that may help you to avoid infection next time.

Puma ransomware virus

Puma is the worst trouble that might happen to you on the Internet It's a typical pillage, only without alive robbers around you: web-criminals penetrate the system and take everything they need, leaving you with a crippled hard drive that contains only wasted data. Puma virus is the clearest illustration of encrypting viruses: it’s easy to pick up and just impossible to remove, but we can assist you with it. In today's entry, we will explain to you the main rules of ransomware's work and how it infested the device. We'll tell you what measures you should take to evade ransomware penetration, and how you can decrypt your files. Don't forget that some the ransomware won't ever get defeated, so if you've got one – your data may be already gone completely. There's a chance that web-criminals made an error to develop the way to neutralize ransomware or to reverse the caused harm. The user may be saved by specific options of the computer, and we will teach you how you can apply it.

What is Puma ransomware

The code of ransomware isn't a big deal, though even the most carelessly developed virus is very perilous, and we’ll explain our point. The catch is about the methods of encryption. Malicious programs don’t literally steal the information. It only needs to infect the hard drive, encode the files and delete the originals, leaving the spoiled versions in their place. There's no use of that data if they're encoded. You can’t use them and can’t bring them to norm. We know several techniques to reconstruct the information, and we've defined each of them in our article.

The encoding viruses, also called ransomware, are the programs that penetrate users’ computers and spoil their files to ask a ransom from them. The penetration is commonly carried out through email spam or 0-day vulnerabilities. Dangerous mail isn't hard to identify – you'll get it from an unknown address, with some files attached to it. If we talk about zero-day vulnerabilities, it’s way substantially more complicated – you'll never know what it is until the computer gets infected so that the most effective method is to daily download the newest updates for the OS and other utilities that you use.

The catch is that all encrypting programs exploit the well-known ciphers, such as the RSA and the AES. These two are literally the most complex ones, and an ordinary user can't break them. Well, you can decrypt them, having a hundred years of usual computer’s working time or several years of work on the very productive computer of the world. We're certain that neither of these variants is suitable a victim. The perfect technique to beat an encrypting virus is to decline its installation, and we'll tell you how to do that.

As soon as the job is finished, virus gives you a letter with directives, and is it appeared – it's too late. There's only one thing you can do now - to eliminate a virus from your device and concentrate on the file recovery. We've said “try” since the chances to handle it without a decryption program are very low.

How to remove Puma

You have to delete a virus until you go on as if it remains in the system – it will start encrypting each file which gets into the device. Even more - each flash drive you're sticking into the infested machine will get encrypted as well. To evade that – uninstall Puma through following this useful advice. Keep in mind that the removal won’t restore the data, and after doing this, you won’t be able to pay the ransom. We recommend doing that as every ransom gained makes web-criminals more to feel their feet in fraud schemes and increases their funds to invent intricate encrypting programs. Significant point is that if you’re forced to deal with fraudsters, there’s no guarantee that the files will be restored after you give out the money. They’ve already spoiled your information, and we don't think that you lean to send them the ransom after that.

Puma decryption instruction

After you uninstall Puma from your PC, and you double-checked it, you should consider the restoration ways. First of all, we have to notice that the very reliable manner is to have the previously saved copies. In case you have the backups of your data and the virus is fully uninstalled – just delete the encrypted information and load the copies. In case there were no backups – the chances to get the data are significantly lower. The only way to restore them is the Shadow Volume Copies. We're talking about the common service of the Windows OS that duplicates each bit of information that was altered. You can find them through custom restoration programs.

Unfortunately, all modern encrypting programs might erase these copies, but if you're accessing the system from an entry that has no master privileges, Puma simply had no ability do that not having the allowance. You might recollect that a few minutes before you've seen a swindler's note you've seen another menu, offering to apply alterations to the system. If you have blocked these changes – your SVC weren't erased, so they might be found and used through special utilities as Recuva or ShadowExplorer. They can be found in the Net. You might get them from the webpages of their creators, with tested instructions.
