KOOK ransomware Removal

About KOOK ransomware virus

KOOK ransomware is regarded as a serious infection, also known as ransomware or file-encrypting malicious program. If ransomware was unknown to you until now, you may be in for a surprise. File encoding malicious program encrypts data using strong encryption algorithms, and once the process is finished, files will be locked and you won’t be able to open them. Ransomware is believed to be such a dangerous infection because file restoration is not necessarily possible in all cases. There’s also the option of buying the decoding utility from crooks but for various reasons, that isn’t the best idea. Before anything else, paying will not ensure that files are decrypted. 

Kook ransomware

Don’t forget that you are dealing with crooks who won’t bother to help you with your files when they can just take your money. Also consider that the money will be used for malware projects in the future. Do you actually want to support something that does billions of dollars in damage. The more people pay, the more profitable it gets, thus attracting more people who are lured by easy money. Situations where you might lose your files are quite frequent so backup would be a better purchase. You can then just remove KOOK ransomware and restore files. And in case you are confused about how the file encoding malicious program managed to infect your system, we’ll explain how it spreads in the paragraph below.

KOOK ransomware distribution methods

You could commonly encounter data encrypting malware added to emails as an attachment or on suspicious download websites. Seeing as these methods are still quite popular, that means that users are somewhat careless when they use email and download files. There’s some possibility that a more sophisticated method was used for infection, as some ransomware do use them. All criminals need to do is add a malicious file to an email, write a plausible text, and pretend to be from a credible company/organization. You’ll often encounter topics about money in those emails, because users are more prone to falling for those types of topics. Oftentimes, crooks pretend to be from Amazon, with the email warning you that there was suspicious activity in your account or some kind of purchase was made. You have to look out for certain signs when opening emails if you want an infection-free computer. It’s critical that you investigate the sender to see whether they are known to you and therefore can be trusted. Don’t make the mistake of opening the attachment just because the sender seems familiar to you, first you’ll have to double-check if the email address matches the sender’s actual email. Obvious grammar errors are also a sign. Another typical characteristic is your name not used in the greeting, if a real company/sender were to email you, they would definitely use your name instead of a typical greeting, such as Customer or Member. Vulnerabilities on your device Vulnerable programs could also be used to infect. All software have weak spots but when they’re discovered, they are regularly patched by software creators so that malware can’t use it to get into a system. Unfortunately, as as may be seen by the widespread of WannaCry ransomware, not all people install fixes, for different reasons. It is crucial that you frequently patch your software because if a weak spot is serious enough, Severe enough weak spots could be easily used by malicious software so make sure all your software are updated. Patches may also be installed automatically.

What can you do about your files

If the ransomware infects your system, it’ll look for certain file types and once it has located them, it’ll encrypt them. Your files will not be accessible, so even if you don’t notice the encryption process, you’ll know something’s not right eventually. All encoded files will have an extension attached to them, which usually help people in recognizing which ransomware they are dealing with. A powerful encryption algorithm may be used, which would make file decryption very hard, if not impossible. You’ll see a ransom note placed in the folders containing your data or it will appear in your desktop, and it should explain how you could restore data. The method they suggest involves you buying their decryption program. The note should clearly display the price for the decryptor but if it doesn’t, it’ll give you an email address to contact the hackers to set up a price. Obviously, we do not suggest you pay, for the reasons already discussed. Only think about giving into the demands when everything else is not a success. Try to recall whether you’ve ever made backup, your files might be stored somewhere. Or maybe there’s a free decryptor. If a malware specialist can crack the data encrypting malicious software, he/she might release a free decryptors. Before you make a choice to pay, look for a decryptor. You wouldn’t have to worry if your system was contaminated again or crashed if you invested some of that sum into backup. If backup is available, just delete KOOK ransomware and then unlock KOOK ransomware files. In the future, make sure you avoid ransomware as much as possible by familiarizing yourself its distribution ways. Stick to legitimate web pages when it comes to downloads, be vigilant when opening email attachments, and ensure you keep your programs updated at all times.

Option 1: free decryption tool

To help victims recover files without paying money, malicious software researchers occasionally release free decryptors. A decryption tool might not be instantly available, but it would likely be released sometime in the future. NoMoreRansom is a great source for decryptors, or using Google is also an option.
