Clients XP OS computer suddenly began displaying the following error message when attempting to start any application including FireFox 3.5.

"This application failed to start because netfgkvbyk.dll was not found. Reinstalling the application may fix this problem."

All applications with the exception of firefox actually start after the error message is dismissed. Firefox refuses to start even after a full reinstallation.

AVG noted in the Virus Vault that it had stopped a Trojan with the netfgkvbyk.dll designation. Since have upgraded to AVG 9.0 Internet Security but it finds nothing.

Each time an application is launched the error message is repeated. A Google search for netfgkvbyk.dll gives zero reults. Malware bytes Anti-malware reports two threats in the registry removed as shown below

Registry Keys Infected:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Ext\Settings\{00009e9f-ddd7-aa59-aa7d-aa4b7d6be000} (Spyware.Passwords) -> Quarantined and deleted successfully.
HKEY_CLASSES_ROOT\idid (Trojan.Sasfix) -> Quarantined and deleted successfully.

Any thoughts on this matter would be appreciated.

Thanks, Boyd

Hello, Its not unusual to receive such an error after using specialized fix tools.

A "Cannot find...", "Could not run...", "Error loading... or "specific module could not be found" message is usually related to malware that was set to run at startup but has been deleted. Windows is trying to load this file but cannot locate it since the file was mostly likely removed during an anti-virus or anti-malware scan. However, an associated orphaned registry entry remains and is telling Windows to load the file when you boot up. Since the file no longer exists, Windows will display an error message. 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 you're 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(s) in the error message.
Right-click on the entry and choose delete.
Reboot your computer and see if the startup error returns.
