Answer 1

Hi! Let me help you.

Please check your startup items.

Press Ctrl + Shift + Esc to open Task Manager.

Go to the Startup apps tab.

Look for any unfamiliar or suspicious entry (especially one related to backupfot800 or Cotrl.vbs).

If found, right-click it and choose Disable.

Restart the machine to check if you will still get the error.

Answer 2

The popup indicates that Windows Script Host is trying to run a startup script that no longer exists:

C:\ProgramData\backupfot800\Cotrl.vbs

This is typically left behind by adware or other unwanted software. To stop the error at startup, remove the invalid startup entry that calls this script.

Use these steps:

1. Open Task Manager startup entries
   1. Press Ctrl + Shift + Esc.
   2. Go to the Startup tab.
   3. Look for any suspicious or unknown entry related to backupfot800, Cotrl.vbs, or anything you do not recognize.
   4. Select it and click Disable.
2. Check the Startup folders
   1. Press Win + R, type:
      • %APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup and press Enter.
      • Then also open: C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup.
   2. Delete any .vbs, .bat, or shortcut that points to C:\ProgramData\backupfot800\Cotrl.vbs or similar.
3. Check the Run registry keys (advanced)
   1. Press Win + R, type regedit and press Enter.
   2. Navigate to these keys:
      • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
      • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
   3. In each, look in the right pane for any value that references backupfot800, Cotrl.vbs, or a script in C:\ProgramData.
   4. If found and clearly unwanted, right‑click the value and choose Delete.
4. Scan for malware
   1. Run a full scan with Windows Security (Virus & threat protection).
   2. Optionally run a scan with a reputable antimalware tool to ensure no other components remain.

After removing the startup entry and restarting, the Windows Script Host error should no longer appear.
