Weui Virus Removal Guide (+Decrypt .weui files)

Weui Virus Ransomware

Weui is a destructive software working as typical ransomware. Michael Gillespie, the widely known malware researcher, very first discovered this new name in the DJVU ransomware family.

Weui was created for the sole purpose to encrypt all popular file types. Logically, as soon as the file encryption is successfully accomplished, the users are unable to get access to them. Weui virus adds its own “.weui” to all the encrypted data. For instance, the file “price_list.xls”, once crypted by Weui, will be entitled as “price_list.xls.weui”. When the encryption is accomplished, Weui puts its own unique text file (_readme.txt) into all the folders that keep the encrypted files.

The message mentioned by _readme.txt asking for the random os really similar to the alerts offered by other ransomware risks coming from the DJVU family. The warning generally indicates that the data has been secured and the only service to get access to it is to use a distinct standalone key. Regretfully, this declaration is absolutely true.

The approach to secure the files used by Weui is not totally investigated. However, there is no doubt that each computer system owner might be issued a special decryption key, which is definitely special. It is extremely hard to recuperate the data without the proper key in location.

“Don’t worry, you can return all your files!”, from text file message:

Don't worry, you can return all your files! virus

One more peculiarity of the Weui ransomware is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the complete control by the crooks who have introduced the Weui virus into the web. In order to get the key and restore the important data, the users are told to get in touch with the scams by means of e-mail or by telegram and to pay the ransom in the amount of $980.

The message likewise states that individuals ought to get in touch with the Weui authors within 72 hours upon the moment of the information encryption. The alert indicates that by doing so the people will get a 50% discount rate, for that reason, the ransom quantity drops down to $490.

No matter what the amount of the ransom is, we highly advise that you do not pay the ransom. There is no assurance that these online scoundrels will keep their promises, so they might not care at all what the victims feel about the file encryption, even when the quantity of the ransom is gotten into their accounts. For this reason, paying ransom often does not lead to a successful healing. So, the users might simply lose their money for absolutely nothing.

Similarly, we urge you not to get in touch with the frauds as they advise. Do not transfer money into their wallets. There are no applications that might crack the Weui virus or bring back the information for free. For that reason, the only proper choice is to restore the information from possible backups (if readily available).
