What Is Adventurer Virus?
Having issues with the Adventurer Virus? Read this article as we will explain here how to get rid of it. Adventurer is a type of ransomware that sneaks into your device without warning and locks your personal files using encryption, making them completely unusable. After taking control, it demands a ransom payment in exchange for file recovery. This kind of threat typically spreads through spam emails and unsafe downloads. It can also hide inside fake updates or software bundles, making detection difficult before the damage is done.
Once Adventurer makes its way into your computer, it starts encrypting your files and appending the .Adventurer extension to them. It also leaves behind a ransom message named README.txt that tries to pressure victims into paying. After our analysis, we discovered that this ransomware is mostly distributed via phishing emails, cracked software, and unsafe websites. It uses high-grade encryption techniques, and even if you pay, there’s no guarantee your data will be restored. Your best option is to eliminate the infection and use trusted file recovery methods. Use the steps below to clean your system safely.

How Did I Get Infected?
Your system may have picked up the Adventurer ransomware through:
- Opening emails with infected files or clicking risky links from unknown senders.
- Using hacked software or downloading from shady sites.
Adventurer Virus – What Does It Do?
Adventurer ransomware encrypts your files using complex methods, leaving them inaccessible without a decryption key. It targets a wide range of file types and may also collect sensitive data before locking your files. The attackers then ask for a cryptocurrency payment in exchange for the unlock tool.
This ransomware connects to remote servers, increasing the chances of additional threats being downloaded. It also hides components in multiple system folders to avoid detection and make removal more complicated:
- %Local%
- %Temp%
- %Windows%
- %SystemDrive%
- %LocalLow%
- %AppData%
- %System%
- %system32%
To make sure it reactivates each time your PC starts, it changes settings in the Windows Registry.
The ransom note, usually saved as README.txt, contains the hackers’ demands and sometimes offers to decrypt a couple of files as proof they have the decryption key:
YOUR FILES ARE ENCRYPTED
Your files, documents, photos, databases and other important files are encrypted.
You will not be able to decrypt it yourself! The only way to recover your files is to buy a unique private key.

Step 3: Clean any registries, created by Adventurer on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by Adventurer there. This can happen by following the steps underneath:
