The Tl30z virus belongs to the Snatch ransomware family. Harmful software of this type encrypts all the data on your PC (images, documents, excel sheets, audio files, videos, etc) and adds its specific extension to every file, leaving the DECRYPT_TL30Z_FILES.txt files in each directory containing encrypted files.
Tl30z virus: what is known so far?
☝️ A strictly correct description for the Tl30z is “a Snatch family ransomware-type malicious agent”.
Tl30z appends its extra .tl30z extension to the name of every encrypted file. For instance, an image named “photo.jpg” will be renamed to “photo.jpg.tl30z”. In the same manner, the Excel sheet named “table.xlsx” will be renamed to “table.xlsx.tl30z”, and so forth.
In every directory with the encoded files, a DECRYPT_TL30Z_FILES.txt text document will be created. It is a ransom money memo. It contains information about the ways of contacting the racketeers and some other information. The ransom note most probably contains a description of how to buy the decryption tool from the tamperers. That is it.

In the image below, you can see what a directory with files encrypted by the Tl30z looks like. Each filename has the “.tl30z” extension appended to it.
How did my computer get infected with Tl30z ransomware?
There are plenty of possible ways of ransomware injection.
There are currently three most exploited methods for evil-doers to have ransomware acting in your digital environment. These are email spam, Trojan introduction and peer-to-peer networks.
If you open your mailbox and see letters that look just like notifications from utility services providers, delivery agencies like FedEx, Internet providers, and whatnot, but whose “from” field is unknown to you, be wary of opening those emails. They are most likely to have a malicious item enclosed in them. Thus it is even riskier to open any attachments that come with letters like these.
As for the peer-to-peer file transfer protocols like BitTorrent or eMule, the danger is that they are even more trust-based than the rest of the Internet. You can never know what you download until you get it. Our suggestion is that you use trustworthy websites. Also, it is reasonable to scan the folder containing the downloaded items with the antivirus as soon as the downloading is done.
How to remove the Tl30z virus?
It is crucial to inform you that besides encrypting your data, the Tl30z virus will probably deploy the Azorult Spyware on your machine to get access to credentials to different accounts (including cryptocurrency wallets). The mentioned program can extract your logins and passwords from your browser’s auto-filling data.
Sometimes criminals would decrypt several of your files so you know that they really have the decryption tool. Since Tl30z virus is a relatively recent ransomware, safety measures designers have not yet found a method to undo its work. However, the decoding instruments are constantly upgraded, so the effective countermeasure may soon arrive.
Understandably, if the evildoers succeed in encrypting someone’s essential data, the hopeless person will probably comply with their demands. Despite that, paying to criminals gives no guarantee that you’re getting your files back. It is still dangerous. After receiving the ransom, the racketeers may deliver a wrong decryption code to the victim. There were reports of racketeers just vanishing after getting the ransom without even writing back.
The best safety measure against ransomware is to have a system restore point or the copies of your critical files in the cloud storage or at least on an external storage. Of course, that might be not enough. The most crucial thing could be that file you were working upon when it all went down. Nevertheless, it is something. It is also reasonable to scan your drives with the anti-malware utility after the OS restoration.
There are other ransomware products, besides Tl30z, that work similarly. For instance, Ccew, Qqmt, Vveo, and some others. The two major differences between them and the Tl30z are the ransom amount and the encoding method. The rest is the same: documents become encrypted, their extensions altered, ransom notes are created in each directory containing encoded files.
Some lucky people were able to decode the arrested files with the aid of the free tools provided by anti-malware experts. Sometimes the criminals mistakenly send the decoding key to the wronged in the ransom note. Such an extraordinary fail allows the injured part to restore the files. But of course, one should never expect such a chance. Remember, ransomware is a criminals’ tool to pull the money out of their victims.
How to avoid ransomware attack?
Tl30z ransomware doesn’t have a superpower, neither does any similar malware.
You can armour your PC from ransomware attack taking several easy steps:
- Ignore any letters from unknown mailboxes with unknown addresses, or with content that has nothing to do with something you are expecting (can you win in a money prize draw without even taking part in it?). In case the email subject is likely something you are expecting, check all elements of the questionable email with caution. A fake letter will always have a mistake.
- Never use cracked or untrusted software. Trojans are often shared as a part of cracked products, most likely under the guise of “patch” which prevents the license check. Understandably, untrusted programs are difficult to distinguish from reliable ones, as trojans sometimes have the functionality you need. Try to find information about this program on the anti-malware message boards, but the best solution is not to use such software.

FAQ
🤔 How can I open “.tl30z” files?Is it possible to open“.tl30z” files?
There’s no way to do it, unless the files “.tl30z” files are decrypted.
🤔 What should I do to make my files accessible as fast as possible?
If the “.tl30z” files contain some really important information, then you probably have them backed up. If not, there is still a function of System Restore but it needs a Restore Point to be previously saved. The rest of the methods require patience.
🤔 What to do if the Tl30z ransomware has blocked my PC and I can’t get the activation key.
🤔 What could help the situation right now?
Many of the encoded files might still be at your disposal
- If you exchanged your important files through email, you could still download them from your online mail server.
- You may have shared photographs or videos with your friends or relatives. Just ask them to give those images back to you.
- If you have initially got any of your files from the Internet, you can try to do it again.
- Your messengers, social media pages, and cloud disks might have all those files as well.
- Maybe you still have the needed files on your old PC, a laptop, mobile, external storage, etc.
USEFUL TIP: You can employ file recovery programs5 to get your lost data back since ransomware arrests the copies of your files, deleting the original ones. In the video below, you can learn how to use PhotoRec for such a restoration, but remember: you can do it only after you kill the virus with an antivirus program.
Also, you can contact the following governmental fraud and scam sites to report this attack:
- In the United States: On Guard Online;
- In Canada: Canadian Anti-Fraud Centre;
- In the United Kingdom: Action Fraud;
- In Australia: SCAMwatch;
- In New Zealand: Consumer Affairs Scams;
- In France: Agence nationale de la sécurité des systèmes d’information;
- In Germany: Bundesamt für Sicherheit in der Informationstechnik;
- In Ireland: An Garda Síochána;
To report the attack, you can contact local executive boards. For instance, if you live in USA, you can have a talk with FBI Local field office, IC3 or Secret Service.
