What is Robaj Ransomware?
Robaj Ransomware is a malicious software that infiltrates computers through various methods, such as phishing emails, malicious downloads, or exploit kits. Once it infects a system, Robaj Ransomware encrypts files on the infected computer, adding a “.robaj” extension to the affected files. This encryption makes the files inaccessible and unreadable without the decryption key.
The ransomware uses a strong encryption algorithm to lock the files, making it nearly impossible to decrypt them without the decryption key. After encrypting the files, Robaj Ransomware creates a ransom note, typically named “HOW_TO_DECRYPT_FILES.txt” or similar, which contains instructions on how to pay the ransom to obtain the decryption key. Unfortunately, there are currently no decryption tools available for .robaj files, so victims are left with few options for recovering their encrypted data. It is important to regularly back up your files to prevent data loss in case of a ransomware attack and to avoid interacting with suspicious emails or downloads to reduce the risk of infection.
There are two solutions to remove Robaj Ransomware and decrypt your files. The first is to use an automated removal tool. This method is suitable even for inexperienced users since the removal tool can delete all instances of the virus in just a few clicks. The second is to use the Manual Removal Guide. This is a more complex way that requires special computer skills.

- Once the scanning process is done, click Recover to restore your files.
- After this, select a destination and click Start Saving to save restored data.
Since new ransomware-type viruses appear almost every day, there is no technical possibility to issue a decryptor for each virus. In this case, the recovery tool comes to the rescue. Despite the fact that this is one of the most effective methods in the absence of a decryptor, this is not 100 percent and not the only way.
Method 2. Restore the system using System Restore
Although the latest versions of Robaj Ransomware can remove system restore files, this method may help you partially restore your files. Give it a try and use standard System Restore to revive your data. The entire process is preferably carried out in Safe Mode with Command Prompt:
For Windows XP/Vista/7 users:
Restart your computer and before your system starts – hit F8 several times. This will prevent system from loading and will show Advanced boot options screen. Choose Safe mode with Command Prompt option from the options list using up and down arrows on your keyboard and hit Enter.
For Windows 8/10 users:

How to prevent your system from Ransomware?
No one is safe from infection with a virus that secretly encrypts your data. But in order to minimize this risk, you need to follow the rules:
- Always make Windows updates on time and keep them up to date. Remember that these updates close the security holes in the system through which the virus can enter your computer.
- The most efficient way to avoid data loss is of course to make a backup of all important data from your computer. It is enough just to synchronize the necessary folders with one of the cloud services, so as not to be afraid to see the text requiring the payment of bitcoins in exchange for a decryption key. It can be a cloud or a remote hard drive on the network. If you store all your files on the Internet, the likelihood of virus infection will be lower. Do not make copies to external hard drives, as this could damage them.
- Since spam email is the most popular form of spreading ransomware-type viruses, the user should never open email attachments without first having scanned them with antivirus. Just clicking on the link or opening the attachment can damage the operating system (Windows) in a few minutes, damage important data, and infect other machines with the virus.
- Ransomware-type viruses often crawl into a system using the Remote Desktop Protocol (RDP). RDP is a legitimate and useful feature that allows a user to take control of a remote computer or virtual machine over a network connection. But, at the same time, this is its Achilles’ heel as it’s poorly secured and has many vulnerabilities that can give hackers easy entry into the victim’s computer. In this case, we advise you to set a different from 3389 TCP port and use a more strong password. You can additionally protect yourself from virus penetration through an RDP connection with the help of a reliable firewall such as GlassWire’s Firewall.
- All previous methods do not matter if you do not have a reliable antivirus. The presence of anti-virus protection on your computer can prevent all these unpleasant surprises. Anti-virus protection will protect you from malware, money loss, time loss, invasion of your personal life. Now the antivirus market is so huge that it is difficult to make a choice in favor of one of them. If you have not decided who to give preference to, we suggest you familiarize yourself with our Top 5 Antivirus Software for Windows.
