About ransomware

CU ransomware is a serious malware infection, categorized as ransomware, which may do severe harm to your device. While ransomware has been a widely reported on topic, you might have missed it, thus you may not be aware of what infection could mean to your computer. When files are encrypted using a powerful encryption algorithm, they will be locked, which means you won’t be able to open them. The reason this malware is categorized as high-level is because ransomware encrypted files are not always possible to decrypt. You do have the option of paying the ransom but many malware researchers do not suggest that. First of all, paying won’t ensure that files are restored. Think about what is there to prevent criminals from just taking your money. Also consider that the money will be used for future malicious software projects. Would you really want to support an industry that already does billions of dollars worth of damage to businesses. And the more people give them money, the more of a profitable business ransomware becomes, and that attracts many people to the industry. Buying backup with the requested money would be a much wiser choice because if you ever run into this type of situation again, you would not need to worry about file loss since they would be recoverable from backup. You could then proceed to data recovery after you erase CU ransomware virus or similar threats. You may find information on how to shield your device from this threat in the below paragraph, in case you are unsure about how the ransomware managed to infect your computer.

How is ransomware distributed

You could generally see ransomware attached to emails or on dubious download site. There’s usually no need to come up with more elaborate methods because a lot of users are pretty negligent when they use emails and download files. More elaborate ways might be used as well, although not as frequently. All criminals need to do is add a malicious file to an email, write some type of text, and pretend to be from a real company/organization. Those emails commonly discuss money because due to the sensitivity of the topic, users are more inclined to open them. Pretty frequently you’ll see big names like Amazon used, for example, if Amazon emailed someone a receipt for a purchase that the person doesn’t remember making, he/she would not wait to open the attached file. When you’re dealing with emails, there are certain signs to look out for if you wish to secure your system. What is essential is to investigate whether you’re familiar with the sender before opening the file attached. If you’re familiar with them, make sure it is genuinely them by carefully checking the email address. Those malicious emails also often contain grammar mistakes, which can be rather easy to notice. The greeting used might also be a hint, as real companies whose email is important enough to open would include your name, instead of universal greetings like Dear Customer/Member. Vulnerabilities on your device Vulnerable software might also be used as a pathway to you system. All programs have vulnerabilities but when they’re identified, they’re frequently fixed by software makes so that malware cannot use it to get into a computer. Unfortunately, as as could be seen by the widespread of WannaCry ransomware, not everyone installs those patches, for one reason or another. It is encourage that you install a patch whenever it is made available. Updates can install automatically, if you find those notifications bothersome.

What does it do

Ransomware only targets specif files, and when they’re found, they are locked almost immediately. Even if what happened wasn’t clear from the beginning, you will certainly know something is not right when files don’t open as normal. You will also see a strange extension attached to all files, which can help identify the correct data encoding malware. Strong encryption algorithms might have been used to encrypt your data, which may mean that you cannot decrypt them. A ransom notification will be put on your desktop or in folders which include locked files, which will notify you about file encryption and how you should proceed. A decryptor will be offered to you, for a price obviously, and crooks will alert to not use other methods because it might damage them. If the price for a decryption software is not displayed properly, you would have to contact the criminals via email. Obviously, we do not think paying is a wise idea, for the reasons already mentioned. Try out every other likely option, before even thinking about buying what they offer. Try to remember whether you’ve recently uploaded your files somewhere but forgotten. Or maybe a free decryptor has been published. If the file encrypting malicious program is crackable, a malware researcher might be able to release a decryption tool for free. Before you decide to pay, consider that option. If you use some of that sum to buy backup, you would not face possible file loss again since your data would be saved somewhere secure. And if backup is available, you can recover data from there after you erase CU ransomware virus, if it still remains on your computer. If you want to avoid ransomware in the future, become aware of how it might get into your device. Ensure you install up update whenever an update is available, you do not open random email attachments, and you only trust safe sources with your downloads.

How to remove CU ransomware virus

Use an anti-malware utility to get the ransomware off your system if it still remains. It may be tricky to manually fix CU ransomware virus because a mistake could lead to further damage. Using an anti-malware software would be much less troublesome. These kinds of programs exist for the purpose of removing these kinds of infections, depending on the program, even preventing them from entering in the first place. Once the anti-malware program of your choice has been installed, simply scan your device and authorize it to get rid of the infection. The utility won’t help decrypt your data, however. If you’re certain your computer is clean, go unlock CU ransomware files from backup.
