An experienced YouTube user named Ranier has posted a video tutorial on how to manually remove the 0KB virus from your computer. Many people have commented that this method worked for them, so it might be worth a try for you too.

According to the video, it seems that a file named "SYSWIN" on your computer is infecting all files and changing them to 0 bytes. Here's the link to the video:

    • Lanier, J. (January 15, 2018).
    • Exe 0KB virus fixed on YouTube.
    • Recovery of files.

Here are the detailed steps:

Step 1: End the SYSMWIN task in Task Manager:

  • Open Task Manager > Find SYSMWIN in the Processes tab > End the process.

Step 2: Go to Startup > Right-click on SYSMWIN and select "Disable"> Right-click on SYSMWIN again and choose "Open File Location."

Step 3: Find and delete the source file.

Note: If SYSMWIN does not show in Task Manager, proceed with the following steps.

Step 4: Right-click on the Windows or Start icon, choose "Search," and input: Show hidden files to open the Folder Options.

Step 5: Select "Show hidden files, folders, and drives," then click "OK" to confirm.

Show Hidden Files

Step 6: Open File Explorer > Navigate to the local C drive > Locate the hidden folder named "BOOT"> Delete this folder since it contains the SYSMWIN file.

Step 7: Empty the Recycle Bin.

Step 8: Open Registry Editor > Go to HKEY_CLASSES_BOOT > Right-click and select "Find"> Input: SYSMWIN, then delete the related registry entries.

By doing so, the SYSWIN program will no longer run on your computer. If you do not delete SYSWIN's registry files, it will run again when you restart your PC after attempting to open an infected 0KB file. After this, you may try to open and scan the infected 0-byte files on your device again.

Method 2: Delete a 0 Byte File by Changing its Extension

Applicable Scope: Fixes all files that suddenly turn to 0 bytes on storage devices or computer hard drives.

In most cases, the saved files on the storage device are renamed to 0KB and the file extension is saved as .000. Thus, you can try changing the file extension of the infected files. You'll be surprised that:

Step 1. Right-click on the device or hard drive partition where the file has become 0 KB and select “Properties.”

Step 2: Click the "Tools" tab, then click "Check for Updates," and then click "OK" to start the scan.

"Check for errors on the storage device"

Step 3: Click “Scan Hard Disk”, and then click “Close” after the scan is completed.

Step 4. Open your hard drive or storage device, and type FOUND.000 in the address bar, then hit Enter.

Step 5: Save the file to another hard drive partition, and change its name and extension.

For example, rename FOUND.000 to Word.doc, Excel.xls, and so on.

Step 6: Open and examine the file's contents.

Your 0-byte file was not repaired, you can reuse it.

Method 3: Resubmit, redownload, or re-send the file

Applies to: Incomplete files that you download, upload, or receive through email online.

Files transmitted over the network or by email often become zero bytes in size due to incorrect operations or incomplete upload/download. The best solution to this problem is to retransmit or redownload the file.

    1. Upload the file again online. 2. Download the file again. 3. Resend the file to your client or colleague. 4. Wait for your client or colleague to resend the file to you.

Method 4: Using a Standard Zip Program

Applies to: Resolving files with unsupported attributes.

Unsupported file attributes often lead to zero-byte files. This is typically caused by the use of certain compression utilities.

Your best bet is to compress the file using standard compression tools and share it with your colleagues, clients, and friends.

Recommended compression tools: WinZip, 7-Zip, WinRAR, and others.

Repairing 0-byte files with zip utility

Method 5: Run CHKDSK

Applies to: Fixes the issue where 0-byte files are generated due to an unknown device error.

When a file system becomes corrupt and files show up as 0 KB, you can try to fix the problem using CMD. Running CHKDSK can resolve the issue of “The disk structure is corrupted and unreadable,” but it may also cause you to lose all your data. Follow these steps:

Step 1: Click “Start” and type cmd into the search box.

Step 2: Right-click on Command Prompt and select Run as administrator.

Step 3. Type CHKDSK F: /f /r /x, and then press Enter.

(F: Replace with the drive letter of the damaged or unreadable device.)

Run chkdsk to fix 0 byte files

This will restore your zero-byte files, and you should be able to use them again.

Method 6: Show Hidden Files

Applies to: Restore hidden files replaced with zero bytes on storage devices.

Sometimes, when your hard drive is infected with some unknown virus, your files might also get hidden and replaced with 0 byte files.

So, here's how you can show hidden files on your device:

Step 1: Right-click the Start or Windows icon, and then select Search.

Show hidden files

Step 3. Under “Advanced settings,” click “Show hidden files, folders, and drives” > click “OK.”

Show all hidden files.

Now you should be able to open your device and see its hidden files.
