How Did I Get Infected?
Security experts warn that Tianrui Virus spreads through multiple methods:

Tianrui Virus – What Does It Do?
Tianrui Virus locks your files using encryption, making them unreadable. It scans for important files and may even upload them online before encrypting. Hackers demand Bitcoin or other cryptocurrencies to unlock the files.
Once it infects your system, it connects to a remote server and downloads extra malware. These files are usually stored in Windows folders like:
- %Local%
- %Temp%
- %Windows%
- %SystemDrive%
- %LocalLow%
- %AppData%
- %System%
- %system32%
The virus also changes the Windows Registry so that it launches every time you restart your computer.
