UNIT09 ransomware. How to remove? (Uninstall guide)

removal by Julie Splinters - - | Type: Ransomware

UNIT09 ransomware – a file locking virus which urges $10 in Bitcoin in exchange for file decryption

UNIT09 ransomware
UNIT09 ransomware is a file locking cyber threat which ads a specific appendix to each encrypted document and displays a ransom-urging message

UNIT09 ransomware appears to be a file-encrypting threat which locks up important documents and demands a ransom in order to restore them. This malicious program infiltrates the system by using secret techniques, for example, spam email messages, infected hyperlinks, and files. .UNIT09 files virus starts the encryption process[1] and locks up all data by using symmetric or asymmetric encryption. Furthermore, all files end up with the .UNIT09 appendix added. Once files are locked like this, they cannot be accessed properly anymore. As a solution, the cybercriminals offer an exchange. They present all conditions in a text message named “$!READ ME.txt”. The crooks demand a $10 BTC price for file decryption and give three days to pay the urged amount. If not, files will be permanently lost. 

Name UNIT09

Danger level Very high. Infects the system and locks up files

Appendix .UNIT09 
Ransom note $!READ ME.txt

Removal Use only reputable tools for removal purposes 

UNIT09 ransomware threatens users that their files will be lost if they do not pay in 72 hours. However, as we can see, the price for decryption is very low:

Dear tomas, Thanks for being a part of UNIT-109
But sadly its time to go. Send $10 in BTC to 1P9NNpNtbhsKaxr2oGkSaqUQb1kB4trS5U
Your files will be unrecoverable after 72 hours. Be quick 😉

However, we suggest not to rush and not to trust the developers. Even though the price is very low, we still advise avoiding any contact with the cybercriminals if possible. They are very likely to scam people and run away with their money. Instead of paying the demanded ransom, you should remove UNIT09 virus from your computer system automatically. We suggest using specific computer tools to detect all malicious content in the system. For this, try Reimage.

After you perform the UNIT09 ransomware removal, you can take a look at some data recovery techniques we have displayed below the text. Even though crooks who create and spread ransomware viruses use unique and hardly-identifiable keys that lock up files, that does not mean you should not try to decrypt them by using other tools. However, keep in mind that you need to terminate the ransomware virus first before you carry on with the file restoring methods.

Moreover, UNIT09 virus might bring other unwanted consequences also. Some of these dangerous infections are capable of permanently erasing Shadow Volume Copies of locked documents. Others have the ability to inject malware programs and make the system even more vulnerable to various infections. Because of these reasons, you should get rid of the cyber threat as soon as you spot encrypted files or the ransom note on your computer's desktop.

Once UNIT09 ransomware infiltrates the targeted computer system (this mostly happens to Windows desktops and laptops), the dangerous cyber threat injects dubious registries straight into the Windows Registry section.[2] Moreover, .UNIT09 files extension ransomware can place unwanted and hazardous files in different locations of your system. All of these components need to be terminated if wanted to get rid of the computer infection for good.

Ransomware infections can be spread by tricky messages

Ransomware usually is brought from rogue email messages that crooks send to random users.[3] You can usually find such letters in the spam section, however, in some cases, the infected letter might fall in your inbox section too, and this is the main reason why you need to be so cautious. Before opening any unexpected email message you should investigate it closely.

First, check the sender and its email address. After that, measure the risk and your expectations, were you waiting for anything important recently? No? So there is no reason of opening the message, better delete it permanently. However, if you have checked the email from all sides and it did not look suspicious to you, you can open it and search for grammar mistakes.

Crooks often leave mistakes in their message texts which lets the victims doubt the legitimacy of such letters. However, even though if the message does not contain any grammar mistakes, we still recommend avoiding opening any attached files or links as it also might be a trick. Some cybercriminals pretend to be from reputable organizations and trick users this way.

Perform the elimination of UNIT09 ransomware and get rid of all related files ASAP

According to cybersecurity experts,[4] ransomware viruses should be erased as soon as possible as these cyber threats might bring unwanted consequences to the user and his/her computer. Remove UNIT09 virus by using automatical computer tools only. Manual elimination is not a possibility in this case as the virus might be too hard to get rid of on your own and you might do just more damage to the computer system or its components.

UNIT09 ransomware removal should be performed after detecting all malware-laden content in the system. We recommend using tools such as Reimage, Malwarebytes MalwarebytesCombo Cleaner, or Plumbytes Anti-MalwareMalwarebytes Malwarebytes to find all malicious components in the infected system. Furthermore, do not forget to perform some system backups, activate the Safe Mode with Networking function, or disable the virus activity by using the System Restore feature.
