Fixing the association settings using Registry editor

Click Start, Run and type CMD

Type the following commands one by one:

cd\windows
regedit

If Registry Editor opens successfully, then navigate to the following key:

HKEY_CLASSES_ROOT \ exefile \ shell \ open \ command

Double-click the (Default) value in the right pane

Delete the current value data, and then type:

"%1" %*
(ie., quote-percent-one-quote-space-percent-asterisk.)

*Interestingly some virus’s have changed the full path of default value to c:\users\HomerJSimpson<yourUserAccount>\appdata\local\happyvirus.exe /runas “%1” %*

Navigate to:

HKEY_CLASSES_ROOT\.exe

In the right-pane, set (default) to exefile

*Interestingly some virus’s have added things like “sfcfile”

Exit the Registry Editor.

Fix with a com executable

You can use a com object to run the fix

reboot and all should be happy. At least with Executables.

Special thanks to Ramesh for giving me the idea on how to do this.
