From what you describe in regards to the error message, the file is probably an orphaned entry
related to a program (or malware) that was set to run at startup. Windows is trying to load this file but cannot locate it since the file may have been removed during an anti-virus or anti-malware scan, the uninstall of a program or use of a specialized fix tool. However, an associated registry entry remains and is telling Windows to load the file when you boot up.
When Windows loads, it looks for any files associated with registry entries for programs that are set to run at startup. If the file was removed but not the registry entry, Windows will display an error message indicating that the file was not found. You need to remove this registry entry so Windows stops searching for the file when it loads.
To resolve this, download Autoruns
, search for the related entry and then delete it.
- Create a new folder on your hard drive called AutoRuns (C:\AutoRuns) and extract (unzip) the file there. (click here if your not sure how to do this.)
- Open the folder and double-click on autoruns.exe to launch it.
- Please be patient as it scans and populates the entries.
- When done scanning, it will say Ready at the bottom.
- Scroll through the list and look for a startup entry related to the file in the error message.
- Right-click on the entry and choose delete.
- Reboot your computer and see if the startup error returns.
