In order to remove Ooza Ransomware, you should first isolate the infected device from the network, identify the specific malware variant and employ powerful antimalware software to remove it. In some cases, it may be necessary to reinstall the operating system. Prevention is key; regularly backing up data and using reputable security tools can help protect against ransomware attacks.
Complete Guide To Uninstall .ooza file virus
Ooza is a dangerous type of ransomware. It sneaks into your computer, finds your important files, and locks them up with strong encryption. You can’t access your files until you pay a ransom. It’s like a digital hostage situation, and it’s a big problem in the world of computer security.
Imagine you can’t open your computer files because they’ve been locked by something called Ooza Ransomware. This is a type of harmful software that sneaks into your device and makes your files unreadable. It’s like someone putting a secret code on your files that only they know.
Ooza is a new version of a similar bad program, named STOP/Djvu Ransomware. It changes your files so you can’t use them, and it adds a special “.ooza” ending to their names. This makes it harder for you to access your important stuff.
The people behind this malicious software say they can fix it, but they want money in return. They promise a special key that can undo the secret code and make your files normal again. But they won’t give you the key unless you pay them.
After Ooza Ransomware encrypts your files, it leaves a message on your computer called “_readme.txt.” This message explains what happened and how much money they want from you. They ask for $980 to give you the key. But if you contact them within three days, they might lower the price to $490. They even let you test the key by sending them one locked file that’s not very important.
To stay safe, remember that you shouldn’t pay these attackers. Paying them doesn’t guarantee they’ll give you the key, and it supports their bad actions. It’s important to keep your device safe by using strong passwords, updating your software, and being careful with what you click on or download.

Your personal ID:
|Name: Ooza Ransomware|
|Category: Ransomware, Crypto-virus|
Features: Known for encrypting users’ files and extorting ransom money from them in exchange for the decryption tools
|Ransom note: _readme.txt|
|Danger level: High|
|Ransom Amount: $490/$980|
|Attackers’ Contact: [email protected], [email protected]|
Symptoms: If you find that your computer files can no longer be opened, and their extensions have been changed (for instance, my.docx.locked), it could be an indication of Ooza virus attack. In such instances, the attacker typically displays a ransom message on your desktop, demanding payment in the form of bitcoins to unlock your files.
Intrusion: Ransomware such as Ooza can infect your system through different sources such as email attachments (usually containing macros), malicious ads, torrent websites, pages that offer free video downloads from YouTube, or host pirated software.
Is paying Ransom Worthy?
Paying the ransom to Ooza Ransomware attackers is generally not recommended because there is no guarantee that they will provide the decryption key or that the key will work. Additionally, paying the ransom funds criminal activity, which can lead to further attacks on other individuals and organizations. Meeting these hackers’ demands can also lead to a cycle of victimization, as they may demand further payments or target the same victim again. So, instead of going for this option, remove Ooza Ransomware from the device without wasting any time before it causes more harm inside the machine.
Tricks Used by Ransomware to Prevent Free Recovery of Encrypted Files
There are some ransomware variants that are designed to execute multiple processes on a targeted computer to carry out various tasks. This initial process launched is winupdate.exe, which is intended to deceive the victims by showing a fake Windows update prompt. This deceptive tactic is aimed at making the victims believe that any system slowdowns they are experiencing are being caused by the update process. Meanwhile, the ransomware simultaneously initiates another process, typically identified by a randomly generated four-character name, which scans the system for specific files to encyrypt. After identifying the target files, the ransomware encrypts them to make them inaccessible to the victim. Finally, to prevent file recovery, the ransomware executes the following CMD command that deletes Volume Shadow Copies from the system:
vssadmin.exe Delete Shadows /All /Quiet
Many Ransomware also tries to eliminate any Windows based methods that could potentially help victims recover their encrypted data for free. The ransomware does this by deleting Volume Shadow Copies, which removes any previously created System Restore Points, leaving the victim with no way to restore their computer to an earlier state. The crypto-virus also alters the Windows HOSTS file by appending a list of domain names and associating them with the localhost IP address. By doing so, any attempt to access a website from the list of blocked domains will instead redirect the user to the local machine, resulting in a DNS_PROBE_FINISHED_NXDOMAIN error message.
The attackers employ this technique to prevent victims from accessing websites, such as those containing information or tools that could help the victims recover their files or remove the ransomware from their system. In addition, the virus generates two text files, bowsakkdestx.txt and PersonalID.txt, which contain details related to the attack, including the victim’s public encryption key and personal ID.
How did my PC get infected with Ooza Ransomware?
There are several ways through which such malware threat may find its way into your computer. Some of the common methods include:
- Spam emails: Suspicious links in spam emails can lead to the installation of viruses.
- Online free hosting resources: Free hosting resources available on the internet can also be a source of malware infection.
- Hidden installation: Viruses can be installed secretly along with other applications, especially freeware or shareware utilities.
- P2P resources: If you employ illegal peer-to-peer (P2P) resources to download pirated software, the risk of virus infection increases.
- Trojans: Trojans can be used to spread Ooza Ransomware by disguising the threat as a legitimate file or program.
Ransomware often spreads through spam emails that contain malicious attachments or links. Cybercriminals create convincing-looking emails that seem legitimate, such as a message from a bank, shipping company, or government agency. These emails entice recipients to download and open the attachment or click on the link. Once clicked, the malicious payload downloads and executes on the user’s computer, infecting it with the ransomware. In some cases, the payload may be embedded within the email itself, allowing it to execute as soon as the email is opened.
Instances have been reported where the Ooza Ransomware was camouflaged as a legitimate tool, masquerading itself as messages that demand the launch of unwanted software or browser updates. Some online scams employ a technique to trick you into installing the virus manually, by making you an active participant in the process. Typically, these fake alerts will not indicate that you are installing ransomware. Instead, the installation will be disguised as an update for a legitimate program like Adobe Flash Player or some other suspicious program. The true nature of the installation will be concealed under these bogus alerts.
Using cracked apps and P2P resources for downloading pirated software can pose a significant threat to your device’s security, and it may lead to the injection of severe malware such as the Ooza Ransomware.
Trojans are a popular attack vector for ransomware. Hackers use Trojans to spread ransomware by disguising the malware as a legitimate file or program. Once a victim downloads and executes the Trojan, the ransomware payload is unleashed on their system, encrypting files and locking the victim out of their data. Trojans can be spread through various channels, including malicious websites, social media platforms, and peer-to-peer networks. Cybercriminals often use social engineering tactics to trick users into downloading and executing Trojans.
Step1. Remove Connected Devices and Isolate the Infected PC
It is very important that you cut off your infected PC with other computers connected in the same local network. Many of the ransomware are designed in such a way that it spreads in network environment. Hence, you need to take some measures to isolate the PC.
There are two basics steps for separate the infected device.
- Disconnect Internet
- Unplug all the external storage device
- Log out of Cloud Storage Accounts (Additional)
Unplug the Ethernet Cable so that all the wired internet connection gets cut off. In case if the infected PC is connected with wireless internet, you have to disconnect it manually through Control Panel.
Go to Control Panel> Search ‘Network and Sharing Center’
Click on ‘Change adapter settings’
Select the internet connect point, right lick on it and choose ‘Disable’. The PC is no longer connected with internet.
Once the PC is disconnected with internet, the next step is to unplug the connected storage device in order to isolate the computer completely. All kind of storage device such as portable hard drives, pen-drives, flash drives etc. is to be removed so that Ooza Ransomware doesn’t encrypts files stored in them.
Go to “My Computer”, right click on the connected storage device and select “Eject”.
There is high possibility that ransomware could take over the software that handles data stored in “cloud storage”. Hence it is strongly recommended that you log out from your cloud storage whether it is through browser or cloud management software.
Step2. Identify the Ransomware that Attacked your Files
It is important to identify the name and type of ransomware that had attacked your work-station so that you can use the right decryption tool for recovering the locked files. This is important because decryption tool for ransowmare released by security experts are exclusive for particular ransomware and their family. If you use incorrect decryption tool which is not designed for removing Ooza Ransomware, then this may damage the locked files permanently.
There are possibly three ways to identity the ranosmware infected your PC. First is to go through the rnasowmare note and see if the name is mentioned or not. For example, In Cerber ransomware note, the name of ransomware is clearly mentioned.
On many occasion, the ransomware name is not mentioned in the note. They contain generic message. Researches shows that different rasnowmare may have same ransom note but they belong from entirely different family or group.
So, if the ransomware note is generic and its name and type is not mentioned, you need to check file extension that it adds on the locked file. When a ransomware locks any file, it appends its own extension name to it in addition. For example, Locky ransomware adds .locky extension name on every files that it encrypts.
Many of the ransomware uses generic extension names as well such as .encrypted, .locked, .crypted etc. In this case, the generic extension name doesn’t reveals anything about the ransomware name and type.
So, if you are unable to identify the ransomware through its note and extension, it is best to visit ID Ransomware website and upload the ransom note you receive or any one of your file that has been encrypted or possibly both.
At present, ID ransowmare database has details of around 1100 different ransomwares. In case if the ransomware that infected your files is not supported by ID ransomware website, you can use internet to search more about the ransomware using keywords like its file extension, crypto wallet address or contact email Id.
Step 3. Search for Ooza Ransomware Decryption Tool to Recover Locked Files
The developer behind ransomware uses highly advanced encryption key to lock the files on the infected PC and hence if it manages to encrypt the file properly, it cannot be decrypted without the correct decryption key. The unlock key is stored in a remote server. Popular ransowmare family such as Dharma, Cerber, Phobos etc. are known to create flawless ransomware and they update their version time to time.
However, there are so many ransomware types that are poorly developed and have flaws in terms of using unique decryption key for each victim, their decryption key are stored on the infected PC instead of remote server and so on. So, the decryption key for such poorly designed ransomware are available on internet. You just have to check some security forums and Online communities to get identical decryption key for poorly designed ransowmare.
To be on safer side, it is recommended to use platforms such as https://www.nomoreransom.org/en/index.html which have tried and tested decryption key for some of the popular ransomware. Its homepage contains a “Decryption Tools” category with search bar option where you can search for decryption key for a particular ransomware.

How to Prevent Ooza Ransomware Attack?
Although no security measures can guarantee complete protection against malware, there are certain precautions you can take to prevent the ransomware from infecting your device. Be vigilant while installing free software, and read through the installer’s additional offers carefully.
Users should be cautious when opening emails from unknown senders or any messages that seem suspicious or out of the ordinary. If the sender or address is unfamiliar, or the content is unrelated to anything you are expecting, it is best not to open the message. It is highly unlikely that you could win a prize in a contest you didn’t enter, so be wary of any emails claiming that you won something. If the email subject appears to be related to something you are anticipating, it is important to thoroughly examine all aspects of the message. Scammers often make mistakes, so carefully scrutinizing the content of the email could help you identify any fraudulent activity. Remember, it is always better to err on the side of caution and avoid opening emails or letters that appear suspicious.
It is also crucial to keep all software and security programs up-to-date to prevent vulnerabilities that ransomware can exploit. Using cracked or unknown programs is a significant risk for Trojan-based ransomware attacks. Cybercriminals often distribute Trojans disguised as legitimate software, such as patches or license checks. However, it is challenging to differentiate between trustworthy software and malicious Trojans since some Trojans may even have the functionality that users seek.
To mitigate this risk, it is crucial to avoid using untrusted programs altogether and only download software from reputable sources. Before downloading any program, users should research it thoroughly and read reviews from trusted sources. It is also recommended to consult anti-malware message boards to gather additional information on any software that may raise suspicion. Ultimately, the best defense against Trojan-based ransomware attacks is to exercise caution and avoid downloading software from untrusted sources.
More Prevention Measures for Individual as well as Organizational Attacks
In case if your PC got infected with highly dangerous ransomware family such as Dharma, it may cause numerous attacks on the work-station. Though, it is still recommended to take some additional precautionary measures. To start, it is crucial to patch and secure Remote Desktop Protocol (RDP) servers with Virtual Private Networks (VPNs) that include multi-factor authentication. This will help protect against unauthorized access and potential breaches.
It is also important for organizations to remain vigilant against phishing attempts, particularly as they adjust to remote working settings. With more employees working from home, the risk of phishing attacks increases, and proper training and education can help reduce this risk.
Moreover, businesses must pay attention to the access granted to service providers and third parties for business purposes. These entities can potentially pose a security threat if not managed properly, and companies must implement strict security protocols and procedures to protect sensitive data and information. By implementing these measures, organizations can better protect themselves against ransomware and other potential security threats.
Some Related FAQs
How can I open files encrypted by Ooza Ransomware? Can I access it myself?
A file that is locked by ransomware cannot be accessed unless it is first decrypted using the decryption key.
What could I do to access the locked files?
In case if you have backup files, use it and don’t worry about the files that got encrypted since you can use it from backup. However remember that in order to use the backup files on same PC, you first have to remove the ransomware infection completely otherwise the backup file will get encrypted as well. For removing the ransomware, it is suggested to use a powerful anti-malware tool.
In case if the backup is not available, you can try “Restore Point” to roll back the System to point where the PC was free from ransomware attack. If these options doesn’t works then you can try your luck with any powerful data recovery tool.
Additionally, there is high possibility that the encrypted files are still with you hence you can check all the possible locations such as sent or received emails, contact your friends, family members to get files like images, videos, etc. that would have shared earlier. Check your cloud storage and social media platforms, old devices including laptop, PC, mobile phones and so on.
