Step-by-Step Juli.A Worm Cleaner Removal Guide The Juli.A worm (also known as the Julia worm or Autorun.inf VB worm) is a malicious script that spreads primarily via USB flash drives and external hard drives. Once active, it hides your original files, replaces them with malicious shortcuts, and lowers your system’s security settings.
Follow this comprehensive, step-by-step guide to completely remove the Juli.A worm from your computer and restore your files. Phase 1: Disconnect and Isolate
Before running any cleaning tools, you must prevent the infection from spreading further or communicating with external servers.
Unplug external drives: Disconnect all secondary USB flash drives, external hard drives, and SD cards except for the one you suspect is infected.
Disconnect from the internet: Unplug your Ethernet cable or turn off Wi-Fi to stop the malware from downloading additional payloads. Phase 2: Terminate Malicious Processes
The worm runs continuously in the background. You must stop its active processes before you can delete its files. Press Ctrl + Shift + Esc to open the Task Manager.

Look through the list for suspicious processes. The Juli.A worm often masquerades under names like wscript.exe, helper.vbs, julia.vbs, or random string names. Right-click the suspicious process and select End Task. Phase 3: Clean Registry and Startup Items
Malware edits the Windows Registry to ensure it launches every time your computer boots up.
Press Windows Key + R, type regedit, and press Enter to open the Registry Editor.
Navigate to the following path:HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
Look at the right pane. Identify any values pointing to .vbs, .vbe, or .exe files located in temporary folders (like AppData). Right-click the malicious entry and select Delete.
Repeat the inspection at this path:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run Phase 4: Delete the Core Malware Files
The worm hides its primary files within your user profile directories. Press Windows Key + R, type %appdata%, and press Enter.
Look for unusual folders or standalone files ending in .vbs or .exe. Common locations include the root of AppData\Roaming or AppData\Local.
Select the malicious files, hold the Shift key, and press Delete to permanently erase them without sending them to the Recycle Bin.
Check your Windows Startup folder by pressing Windows Key + R, typing shell:startup, and pressing Enter. Delete any shortcut pointing to the worm. Phase 5: Unhide and Recover Files on Affected Drives
The Juli.A worm does not usually delete your data; instead, it changes file attributes to make them invisible and creates look-alike shortcuts to trick you into clicking them.
Plug in your infected USB drive and note its drive letter (e.g., G:).
Open the Start Menu, type cmd, right-click Command Prompt, and select Run as administrator. Type your drive letter followed by a colon and press Enter: G: Use code with caution.
Delete all the fake shortcuts created by the worm by executing: del.lnk Use code with caution.
Run the following command to strip the “hidden” and “system” attributes from your original files: attrib -h -r -s /s /d . Use code with caution.
Open your USB drive via File Explorer. Your original files should now be visible in their original folders, alongside a newly revealed, malicious .vbs or autorun.inf file. Delete those malicious files immediately. Phase 6: Run a Deep Security Scan
To ensure no remnants or secondary infections remain, perform a thorough system scan. Reconnect your internet connection.
Download and install a reputable anti-malware tool like Malwarebytes or use the built-in Windows Defender. Update the virus definitions to the latest version.
Perform a Custom Scan or Full Scan, ensuring that both your local C: drive and your external USB drives are selected. Quarantine and remove any threats detected by the software. Prevention Tips Going Forward
Disable AutoRun/AutoPlay: Prevent Windows from automatically executing scripts when a USB drive is inserted. Go to Settings > Devices > AutoPlay and turn it off.
Show File Extensions: Always keep file extensions visible so you can spot a fake folder that is actually an .exe or .vbs file.
Scan before opening: Get into the habit of right-clicking any external drive and scanning it with your antivirus before opening it.
