What is OlSaveLock ransomware?
OlSaveLock ransomware is a virus that encrypts user files and demands money in exchange for the decryption key. Cybercriminals frequently utilize Bitcoin to gather money because it provides them with anonymity. Following payment, the victim should get the decryption key, which will allow them to regain access to their data. There’s no assurance they’ll get the key, and even if they do, there’s no guarantee their data will be decrypted properly. OlSaveLock ransomware is well-known for eluding detection by standard antivirus software. It utilizes a variety of techniques to avoid detection and removal, making it difficult to detect and remove. When it infects a computer, it begins encrypting files. When it infects a system, it starts encrypting data and shows a message asking for money in exchange for the decryption key.
How Does OlSaveLock Ransomware Infect Systems?
OlSaveLock ransomware typically infects systems through email phishing campaigns, malvertising, or exploit kits. Email phishing campaigns involve sending emails that appear to be from legitimate sources, such as banks, government agencies, or other trusted organizations. These emails contain links or attachments that, when clicked or opened, install the malware onto the system.
Malvertising involves the use of malicious advertisements on legitimate websites. These ads contain links that, when clicked, redirect the user to a website that installs the malware onto their system. Exploit kits are packages that contain a collection of exploits that can be used to penetrate systems. Cybercriminals use these kits to identify vulnerabilities in a system and use them to install the malware.
The Impact of OlSaveLock Ransomware Attacks
OlSaveLock ransomware attacks can have a significant impact on individuals and businesses. The loss of sensitive data can result in financial losses, damage to reputation, and legal consequences. Furthermore, paying the ransom does not guarantee the return of the encrypted files or protection from future attacks.
In addition to the financial impact, OlSaveLock ransomware attacks can also cause emotional distress to victims. The loss of personal or sensitive data can be devastating, especially if it contains irreplaceable memories or information.
Once encryption is done, all user’s files will be appended with the “.olsavelock31” extension. For example, file “IMG2054.jpg” will turn into “IMG2054.jpg.olsavelock31“. Afterward, the ransomware will drop a file with a ransom note – “How_to_back_files.html” that contains kidnappers’ demands. However, we do not recommend you do this, because no one can ensure that they send you the decryption tool even if the payment is transferred.

The only effective method to restore files is to copy them from a saved backup. If you don’t have a suitable backup, you may use third-party recovery software such as Stellar Data Recovery |
How to remove OlSaveLock ransomware?
Recommended Solution:
Try SpyHunter
SpyHunter is a powerful tool that is able to keep your Windows clean. It would automatically search out and delete all elements related to malware. It is not only the easiest way to eliminate malware but also the safest and most assuring one. The full version of SpyHunter costs $42 (you get 6 months of subscription).

Try Stellar Data Recovery
Stellar Data Recovery is one of the most effective tools that can recover lost and corrupted files — documents, emails, pictures, videos, audio files, and more — on any Windows device. The powerful scan engine can detect compromised files and finally save them to specified destination. Despite its advancedness, it’s very concise and simple so that even the most inexperienced user can figure it out.
Try MailWasher
Email security is the first line of defense against ransomware viruses. To do this, we recommend that you use MailWasher. MailWasher blocks ransomware viruses coming through spam and phishing, and automatically detects malicious attachments and URLs. In addition, malicious messages can be blocked even before the recipient opens them. Since the main source of the spread of ransomware viruses are infected emails, antispam significantly reduces the risk of a virus appearing on your computer.
After the virus is completely removed from your system, you can already start restoring your files directly.
How to decrypt files infected by OlSaveLock Ransomware?
Method 1. Restore your files with the help of Recovery Tool
In case your PC has been attacked by ransomware, you may restore your files by using file recovery software. Stellar Data Recovery is one of the most effective tools that can recover lost and corrupted files — documents, emails, pictures, videos, audio files, and more — on any Windows device. The powerful scan engine can detect compromised files and finally save them to specified destination. Despite its advancedness, it’s very concise and simple so that even the most inexperienced user can figure it out.
- Run Stellar Data Recovery.
- Select type of files you want to restore and click Next.
- Select the drive and folder where your files are located and date that you want to restore them from and press Scan.
- 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 OlSaveLock 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:
- Click the Start button, then select Settings
- Click Update & Security, then select Recovery and click Restart now.
- After your device reboots, go to Troubleshoot > Advanced options >Startup Settings > Restart
- After your PC restarts, you should press F5 key to Enable Safe Mode with Command Prompt.
After the system is loaded in Safe Mode with Command Prompt, do following:
- In the Command Prompt window, type cd restore and hit Enter.
- Then type rstrui.exe and hit Enter again.
- Once a new window shows up, click Next.
- Choose the date before the infection appearance and click Next again
- In the opened pop-up window, click Yes to start system restore.
Method 4. Roll the files back to the previous version
Previous versions can be copies of files and folders created by Windows Backup (if it is active) or copies of files and folders created by System Restore. You can use this feature to restore files and folders that you accidentally modified or deleted, or that were damaged. This feature is available in Windows 7 and later versions.
- Click the encrypted file and choose Properties
- Open the Previous Version tab
- Select the latest version and click Copy
- Click Restore
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:
1. 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.
2. 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.
3. 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.
Try MailWasher
Email security is the first line of defense against ransomware viruses. To do this, we recommend that you use MailWasher. MailWasher blocks ransomware viruses coming through spam and phishing, and automatically detects malicious attachments and URLs. In addition, malicious messages can be blocked even before the recipient opens them. Since the main source of the spread of ransomware viruses are infected emails, antispam significantly reduces the risk of a virus appearing on your computer.
3. 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
5. 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
