How to recover
.tuid files
from Windows

Hello. All of the files on my computer are locked with .tuid extension. I don't want to pay, but it seems that there are no options besides that. Are there any options for decryption of the virus? Can you help me with file recovery or decryption?

The Tuid file virus is the threat that affects a lot of the machines besides the files it locks and makes useless. It can hide anywhere you transmit files, and programs, including through pirate platforms and even emails. This makes it so dangerous because these days we want everything as quickly and easily accessible to us digitally, so steps get skipped and problems overlooked.

The Djvu ransomware family is the one this ransomware derives from. This is the 440th version on the list. These versions are spread mainly via torrents and pirating platforms because NBA video game cracks, Adobe software license versions, and other popular program packages can be sent with the malware payload behind the user's back.[ref en-1]

Tuid ransomware is focusing on file locking as this is what provides the reason behind money demands. File locking is quick and then virus creators can demand their ransoms from people directly via those ransom note messages sent via _readme.txt.

The infection family has been spreading since 2018, and it is more advanced than ever. The creator of this threat relies on the online id forming method, so decryption becomes impossible. The threat actors introduced a new way for files to be encoded in August 2019. Since then all versions are using the online ids that are unique for each device and keep decryption options limited.

How to recover encrypted files?

There is a chance that your files might get locked again if you try to remove the ransomware yourself. However, paying ransomware creators is never a good idea.[ref en-2] You need professional assistance from proper tools or cybersecurity specialists that know what they are doing. The file recovery might not give positive results when you still have the virus running on the machine.

We know that your main focus and worry are those encoded files, but don't forget about virus removal. The good news is there are a lot of features to help with this. You should also take care of the functions affected by the virus infection and once the ransomware is terminated, you can move to Tuid ransomware file recovery.
