Ttza virus Removal Guide
What is Ttza ransomware?
Ttza ransomware is a dangerous virus that encrypts users' personal files
Ransomware infections can result in permanent data loss if there are no backups
Ttza ransomware is a malicious variant belonging to the Djvu ransomware family. Its main goal is to target infected computers and encrypt user data inside, making it impossible to view the files until a ransom is paid. Ttza does not distinguish between different file kinds; system folders are unaffected while documents, photos, audio/video recordings, and archives are all subject to its encryption. Therefore, if left unchecked, this ransomware could cause irreparable harm to a victim's data.
Ttza's capacity to function covertly, frequently leaving victims unaware that their files have been encrypted until it's too late, is one of its particularly disturbing characteristics. Ttza marks compromised files with a .ttza file extension to better conceal its activity. In other instances, it might use misleading strategies to hide its activity, like displaying fake Windows update pop-ups.
|TYPE||Ransomware, file-locking malware|
|MALWARE FAMILY||Djvu ransomware|
|FILE RECOVERY||There is no guaranteed way to recover locked files without backups. Other options include paying cybercriminals (not recommended, might also lose the paid money), using Emisoft's decryptor (works for a limited number of victims), or using third-party recovery software|
|MALWARE REMOVAL||After disconnecting the computer from the network and the internet, do a complete system scan using a security program|
|SYSTEM FIX||As soon as it is installed, malware has the potential to severely harm some system files, causing instability problems, including crashes and errors. Any such damage can be automatically repaired by using FortectIntego PC repair|
The ransom note
Ttza ransomware drops a _readme.txt ransom note which reads as follows:
Don't worry, you can return all your files!
All your files like pictures, databases, documents and other important are encrypted with strongest encryption and unique key.
The only method of recovering files is to purchase decrypt tool and unique key for you.
This software will decrypt all your encrypted files.
What guarantees you have?
You can send one of your encrypted file from your PC and we decrypt it for free.
But we can decrypt only 1 file for free. File must not contain valuable information.

Your personal ID:
“ATTENTION!” is written in a bold header at the top of the ransom note, pleading for immediate attention. The victim's anxiety levels are immediately increased by this strong start, which establishes a tone of urgency and intimidation. The note asserts that there is a means to recover the victim's files in an effort to calm their concerns. It claims that a strong algorithm and a special key have been used to encrypt all of their important data, including images, databases, papers, and other necessities. It suggests that the victim is vulnerable because they can't access their own files without this key.
The note explains the pricing, stating that the decryption key and software have a hefty $980 price tag. The attackers suggest a 50% discount if the victim contacts them within the first 72 hours, making the ransom only $490, to encourage prompt cooperation. Victims are strongly warned against paying the ransom for a number of convincing reasons, despite the menacing tone and the urgency implied in the ransom note:
- Lack of Guarantee: There is no assurance that paying the ransom will result in the safe return of the encrypted files. Cybercriminals may not provide the decryption key or tool even after receiving the payment.
- Encouraging Criminal Activity: Paying the ransom financially supports criminal activities and incentivizes cybercriminals to perpetrate further attacks on unsuspecting victims.
- Risk of Further Exploitation: Sharing personal information or financial details with cybercriminals can lead to identity theft, fraud, or potentially make the victim vulnerable to future attacks.
- Legal Consequences: In many jurisdictions, paying a ransom to cybercriminals is illegal, and victims could face legal repercussions for their involvement in criminal activities.
- Cybersecurity Best Practices: Instead of complying with the ransom demands, victims are encouraged to seek the assistance of law enforcement and cybersecurity experts to explore alternative methods of data recovery. Preventive measures, such as regular data backups and robust cybersecurity practices, should be prioritized to avoid falling victim to ransomware attacks in the first place.
It is important to not give in to scare tactics used by cybercriminals
Ttza ransomware represents a serious threat and, if left unattended, has the power to destroy both your machine and your data. It is imperative to act right away by deploying anti-malware programs to remove the virus from your system in order to prevent future damage. By identifying and removing this specific threat, these specialized utilities will increase the security of your system.
If you don't get rid of this harmful software right once, it could continue to harm your device and eventually make data recovery impossible. It is essential to use reliable antivirus detection systems like Malwarebytes and SpyHunter 5Combo Cleaner in conjunction with anti-malware solutions in order to protect your system efficiently.
A thorough system scan will help you find any potential dangers, such as viruses and possibly dangerous apps. You can stop the ransomware from spreading further if you swiftly remove any threats, malware, or damaging data from your device. When recovering files, extreme caution must be taken to guarantee that they have not been damaged in any manner.
Decrypt .ttza files
Data recovery may be possible if your computer has been infected with a Djvu ransomware variant using the Emsisoft decryptor program. It's crucial to understand, though, that not everyone may be able to use this approach. Its success is dependent on a unique circumstance: the ransomware had to use an offline ID to encrypt your data, which shows that it was unable to connect to its remote servers.
Even if your scenario fits this description, there is still one more thing to think about. Someone from the affected group must pay the ransom to the attackers, obtain the offline key, and then give it to the security experts at Emsisoft in order to use the decryptor. As a result, it might not be possible to restore your encrypted files right away. It's suggested to try the operation again later if the decryptor determines that your data was truly locked with an offline ID but cannot currently be restored.
To utilize the decryptor, you will also need to upload a pair of files – one that is encrypted and one that remains unaltered and healthy – to Emsisoft's servers as part of the decryption process.
- Download the app from the official Emsisoft website.
- After pressing Download button, a small pop-up at the bottom, titled decrypt_STOPDjvu.exe should show up – click it.
- If User Account Control (UAC) message shows up, press Yes.
- Agree to License Terms by pressing Yes.
- After Disclaimer shows up, press OK.
- The tool should automatically populate the affected folders, although you can also do it by pressing Add folder at the bottom.
- Press Decrypt.
From here, there are three available outcomes:
- “Decrypted!” will be shown under files that were decrypted successfully – they are now usable again.
- “Error: Unable to decrypt file with ID:” means that the keys for this version of the virus have not yet been retrieved, so you should try later.
- “This ID appears to be an online ID, decryption is impossible” – you are unable to decrypt files with this tool.
System file recovery
Malware poses a serious risk to a computer's functionality by disrupting the Windows registry database widely, impairing crucial boot-up procedures, interfering with other crucial components, and frequently leading to the deletion or corruption of DLL files, among other problems. Sometimes when malware causes file damage, conventional antivirus software may not be able to restore system integrity. This may result in enduring stability problems that can only be successfully fixed by completely reinstalling the Windows operating system.
We advise the use of FortectIntego, a proprietary and unique repair technology, to meet these difficult challenges. This program not only excels at dealing with malware infections' aftereffects, but it also demonstrates that it is highly effective at fixing a wide variety of Windows errors that are unrelated to malware, such as Blue Screen errors, system freezes, inconsistent registry settings, and the repair of corrupt DLL files.
Getting rid of Ttza virus. Follow these steps
Important steps to take before you begin malware removal
File encryption and ransomware infection are two independent processes (although the latter would not be possible without the former). However, it is important to understand that malware performs various changes within a Windows operating system, fundamentally changing the way it works.
IMPORTANT for those without backups! →
If you attempt to use security or recovery software immediately, you might permanently damage your files, and even a working decryptor then would not be able to save them.
Before you proceed with the removal instructions below, you should copy the encrypted files onto a separate medium, such as USB flash drive or SSD, and then disconnect them from your computer. Encrypted data does not hold any malicious code, so it is safe to transfer to other devices.
The instructions below might initially seem overwhelming and complicated, but they are not difficult to understand as long as you follow each step in the appropriate order. This comprehensive free guide will help you to handle the malware removal and data recovery process correctly.
If you have any questions, comments, or are having troubles with following the instructions, please do not hesitate to contact us via the Ask Us section.
It is vital to eliminate malware infection from the computer fully before starting the data recovery process, otherwise ransomware might re-encrypt retrieved files from backups repeatedly.
Restore Windows "hosts" file to its original state
Some ransomware might modify Windows hosts file in order to prevent users from accessing certain websites online. For example, Djvu ransomware variants add dozens of entries containing URLs of security-related websites, such as 2-spyware.com. Each of the entries means that users will not be able to access the listed web addresses and will receive an error instead.
Here's an example of “hosts” file entries that were injected by ransomware:
In order to restore your ability to access all websites without restrictions, you should either delete the file (Windows will automatically recreate it) or remove all the malware-created entries. If you have never touched the “hosts” file before, you should simply delete it by marking it and pressing Shift + Del on your keyboard. For that, navigate to the following location:
Restore files using data recovery software
Since many users do not prepare proper data backups prior to being attacked by ransomware, they might often lose access to their files permanently. Paying criminals is also very risky, as they might not fulfill the promises and never send back the required decryption tool.
While this might sound terrible, not all is lost – data recovery software might be able to help you in some situations (it highly depends on the encryption algorithm used, whether ransomware managed to complete the programmed tasks, etc.). Since there are thousands of different ransomware strains, it is immediately impossible to tell whether third-party software will work for you.
Therefore, we suggest trying regardless of which ransomware attacked your computer. Before you begin, several pointers are important while dealing with this situation:
- Since the encrypted data on your computer might permanently be damaged by security or data recovery software, you should first make backups of it – use a USB flash drive or another storage.
- Only attempt to recover your files using this method after you perform a scan with anti-malware software.
Install data recovery software
- Download Data Recovery Pro.
- Double-click the installer to launch it.
- Follow on-screen instructions to install the software.
- As soon as you press Finish, you can use the app.
- Select Everything or pick individual folders where you want the files to be recovered from.
- Press Next.
- At the bottom, enable Deep scan and pick which Disks you want to be scanned.
- Press Scan and wait till it is complete.
- You can now pick which folders/files to recover – don't forget you also have the option to search by the file name!
- Press Recover to retrieve your files.
Create data backups to avoid file loss in the future
One of the many countermeasures for home users against ransomware is data backups. Even if your Windows get corrupted, you can reinstall everything from scratch and retrieve files from backups with minimal losses overall. Most importantly, you would not have to pay cybercriminals and risk your money as well.
Therefore, if you have already dealt with a ransomware attack, we strongly advise you to prepare backups for future use. There are two options available to you:
- Backup on a physical external drive, such as a USB flash drive or external HDD.
- Use cloud storage services.
The first method is not that convenient, however, as backups need to constantly be updated manually – although it is very reliable. Therefore, we highly advise choosing cloud storage instead – it is easy to set up and efficient to sustain. The problem with it is that storage space is limited unless you want to pay for the subscription.
Using Microsoft OneDrive
OneDrive is a built-in tool that comes with every modern Windows version. By default, you get 5 GB of storage that you can use for free. You can increase that storage space, but for a price. Here's how to setup backups for OneDrive:
- Click on the OneDrive icon within your system tray.
- Select Help & Settings > Settings.
- If you don't see your email under the Account tab, you should click Add an account and proceed with the on-screen instructions to set yourself up.
- Once done, move to the Backup tab and click Manage backup.
- Select Desktop, Documents, and Pictures, or a combination of whichever folders you want to backup.
- Press Start backup.
After this, all the files that are imported into the above-mentioned folders will be automatically backed for you. If you want to add other folders or files, you have to do that manually. For that, open File Explorer by pressing Win + E on your keyboard, and then click on the OneDrive icon. You should drag and drop folders you want to backup (or you can use Copy/Paste as well).
Using Google Drive
Google Drive is another great solution for free backups. The good news is that you get as much as 15GB for free by choosing this storage. There are also paid versions available, with significantly more storage to choose from.
You can access Google Drive via the web browser or use a desktop app you can download on the official website. If you want your files to be synced automatically, you will have to download the app, however.
- Download the Google Drive app installer and click on it.
- Wait a few seconds for it to be installed.
- Now click the arrow within your system tray – you should see Google Drive icon there, click it once.
- Click Get Started.
- Enter all the required information – your email/phone, and password.
- Now pick what you want to sync and backup. You can click on Choose Folder to add additional folders to the list.
- Once done, pick Next.
- Now you can select to sync items to be visible on your computer.
- Finally, press Start and wait till the sync is complete. Your files are now being backed up.
Report the incident to your local authorities
Ransomware is a huge business that is highly illegal, and authorities are very involved in catching malware operators. To have increased chances of identifying the culprits, the agencies need information. Therefore, by reporting the crime, you could help with stopping the cybercriminal activities and catching the threat actors. Make sure you include all the possible details, including how did you notice the attack, when it happened, etc. Additionally, providing documents such as ransom notes, examples of encrypted files, or malware executables would also be beneficial.
Law enforcement agencies typically deal with online fraud and cybercrime, although it depends on where you live. Here is the list of local authority groups that handle incidents like ransomware attacks, sorted by country:
- USA – Internet Crime Complaint Center IC3
- United Kingdom – ActionFraud
- Canada – Canadian Anti-Fraud Centre
- Australia – ScamWatch
- New Zealand – ConsumerProtection
- Germany – Polizei
- France – Ministère de l'Intérieur
If your country is not listed above, you should contact the local police department or communications center.
Manual removal using Safe Mode
Manual removal guide might be too complicated for regular computer users. It requires advanced IT knowledge to be performed correctly (if vital system files are removed or damaged, it might result in full Windows compromise), and it also might take hours to complete. Therefore, we highly advise using the automatic method provided above instead.
Step 1. Access Safe Mode with Networking
Manual malware removal should be best performed in the Safe Mode environment.

How to prevent from getting ransomware
Protect your privacy – employ a VPN
There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals.
No backups? No problem. Use a data recovery tool
If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.
If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
