Introduction
Got infected by 000.exe and can't figure out how to remove it? This guide will help you get rid of that malware on any Windows computer — without antivirus software or outside help.
000.exe is not as destructive as deep ransomware or MBR malware. It mainly:
- Spams runaway message boxes
- Creates junk files
- Edits small registry values
- Changes your wallpaper
- Drops startup entries
Your data and bootloader are safe, only cosmetic and annoying changes are made.
Do not download malware or execute unknown scripts on a real machine. All demonstrations on ArsenTech are performed inside isolated virtual machines. Readers should follow the tutorial carefully and fully understand the steps before removing malware.

Step 1 - Stopping the Message Boxes
000.exe spams message boxes every millisecond, making your PC unusable.
1. Stop CMD-based popups
Open Command Prompt as Administrator and type:
taskkill /f /im cmd.exeThis stops the chained message box commands.
2. Stop the main spammer executable
Open Command Prompt as Administrator again:
taskkill /f /im runaway.exeThis immediately kills the process responsible for generating thousands of popups.
runaway.exe is an executable dropped by 000.exe to repeatedly launch spam message boxes.
Once finished, your desktop should be clean and usable.
Step 2 - Delete Files Planted by 000.exe
000.exe creates .txt and .rtf files on the desktop named UR NEXT
To delete all of them at once, press:
Ctrl+Ato select all files on your desktop. Then permanently delete them:
Shift+DelEmpty your Recycle Bin afterward. This removes all visible leftovers from the malware.
Step 3 - Restore Your Theme & Desktop Background
000.exe replaces your wallpaper with a corrupted image.
To restore your desktop appearance:
- Open Settings
- Go to Personalization → Themes

Your system should now visually appear normal again.
Step 4 - Registry changes
Only modify the registry keys shown below. Editing unrelated values may corrupt Windows and cause boot failure.
Open the run dialog:

Registry Change 1 - Enable Task Manager
Navigate to:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System
Right-click and delete DisableTaskMgr
Task Manager will work again after restarting your PC.
Registry Change 2 - Change the Icon of the Text files
000.exe points .txt icons to a malicious file. Reset it to the Windows default by navigating to:
HKEY_CLASSES_ROOT/txtfile/DefaultIcon
And changing the (Default) entry:
| Before | After |
|---|---|
C:\Users\<username>\AppData\Local\temp\icon.ico | C:\Windows\system32\imageres.dll,-102 |
This restores the normal text document icon. Changes take effect after a restart.
Step 5 - Remove Startup Entries
Open File Explorer and go to:
%programdata%/Microsoft/Windows/Start Menu/Programs/Startup
Delete rniw.exe
rniw.exe rniw.exe is a startup program created by 000.exe to re-enable its message boxes.
